Physicists at Wake Forest University have developed a fabric that doubles as a spare outlet. When used to line your shirt — or even your pillowcase or office chair — it converts subtle differences in temperature across the span of the clothing (say, from your cuff to your armpit) into electricity. And because the different parts of your shirt can vary by about 10 degrees, you could power up your MP3 player just by sitting still. According to the fabric’s creator, David Carroll, a cellphone case lined with the material could boost the phone’s battery charge by 10 to 15 percent over eight hours, using the heat absorbed from your pants pocket.

Soon, coffee isn’t going to taste like coffee — at least not the dark, ashy roasts we drink today. Big producers want uniform taste, and a dark roast makes that easy: it evens out flavors and masks flaws. But now the best beans are increasingly being set aside and shipped in vacuum-sealed packs (instead of burlap bags). Improvements like these have allowed roasters to make coffee that tastes like Seville oranges or toasted almonds or berries, and that sense of experimentation is trickling down to the mass market; Starbucks, for instance, now has a Blonde Roast. As quality continues to improve, coffee will lighten, and dark roasts may just become a relic of the past. Oliver Strand
Your spandex can now subtly nag you to work out. A Finnish company, Myontec, recently began marketing underwear embedded with electromyographic sensors that tell you how hard you’re working your quadriceps, hamstring and gluteus muscles. It then sends that data to a computer for analysis. Although the skintight shorts are being marketed to athletes and coaches, they could be useful for the deskbound. The hope, according to Arto Pesola, who is working on an advanced version of the sensors, is that when you see data telling you just how inert you really are, you’ll be inspired to lead a less sedentary life.

The problem with laptops and tablets, says Mark Rolston of the design firm Frog, is that they’re confined by a screen. He wants to turn the entire room into a monitor, where you can have the news on your kitchen table while you place a video call on your fridge. And when you’re done, you can swipe everything away, like Tony Stark in “Iron Man.”Clay Risen
This 15-minute shampoo treatment begins when you lean your head back into a machine that looks like a sink at the salon. First it maps your scalp, then it shoots streams of warm water and foam shampoo from its 28 nozzles before 24 silicone “fingers” work up a lather. One conditioning mist, scalp massage and light blow-dry later, you’re done. Nathaniel Penn

What are your two best million-dollar ideas?
The first is permanent sunblock. No one likes putting the stuff on, so there should be a one-time treatment that embeds the skin with a permanent level of S.P.F. 30, akin to having Lasik eye surgery once and then forgetting about it. Sunburn vanquished like smallpox. The other is the “brain map” — a technology that maps out every neural connection in your mind and then, effectively, stores your brain on your hard drive. That information — more than your DNA even — is you.

Here’s an old idea whose time has come again. The bearing system that allows the bike to turn can be locked so that a thief can’t steer his stolen bike. The lock is internal, meaning that he’d have to destroy the bike to ride it away.
No more greasy chains
An updated shaft drive — which replaces the chain with a rod and internal gear system — would be perfect for urban riders. They’re popular in China right now, but new versions will be lighter and have more sophisticated gearing.
One-piece plastic and carbon-fiber frames
Plastic frames were tried back in the ’90s, but they were too heavy. The materials and technology have improved. Thermoplastics are cheap and practically impervious to the elements.

Your car is already able to call for help when an accident occurs, but within a few years, it’ll tip paramedics off to probable injuries too. E.M.T.’s would know the likelihood of internal bleeding or traumatic head injury, for example, before arriving on the scene, which would help them decide whether to move you to a Level 1 trauma center or a standard emergency room. Researchers at the University of Michigan International Center for Automotive Medicine have created the predictive models by cross-referencing the crash data provided by sensors on cars, like speed and location of impact, with 3-D scans of accident victims.

The typical plane cabin is drier than the Arizona desert, and the air is so thin it feels as if you were visiting Machu Picchu. This brutal environment contributes to the parched, exhausted feeling you get after you fly. But there are already planes in the air — made mostly of carbon fiber — that solve this problem. Carbon fiber is markedly stronger by weight than the aluminum used for most existing planes, which means that the interior air pressure can be adjusted to more comfortable levels without the risk of damaging the fuselage. Airlines also keep humidity levels low now to prevent the plane’s metal skin from corroding, but carbon fiber doesn’t rust. That will allow a new system to maintain humidity at a more comfortable 15 percent (up from around 5 to 10 percent). Japan Airlines and Nippon Airlines bought the first crop of these new planes. They’re currently in service between Tokyo and Boston.

The industrial designer Jiang Qian has conceived of a subway strap that’s also a video game. It has a button on each side that you push with your thumb as you hang on; instead of a joystick, you control movement by twisting the handle from side to side. Jiang imagines that new types of games could be created, where keeping your balance while the train is in motion is part of the challenge. And unlike Angry Birds on your phone, Strap Game (that’s the official name) will alert you when your stop is approaching. Jenna Wortham

What technology that you wanted to put into a film were you not able to because it seemed too far-fetched?
In “Minority Report,” Tom Cruise gets into a car that drives itself. We considered giving him neural control of that car, but we deliberately held back on how far biology could go. It would have overwhelmed the story. And here we are today with real neurological control of machines. It’s transformative technology. In 50 years, you’ll be able to drive cars with your mind.
If you slump down when you’re typing on an ErgoSensor monitor by Philips, it’ll suggest that you sit up straighter. To help office workers avoid achy backs and tired eyes, the device’s built-in camera follows the position of your pupils to determine how you are sitting. Are you too close? Is your neck tilted too much? Algorithms crunch the raw data from the sensor and tell you how to adjust your body to achieve ergonomic correctness. The monitor can also inform you that it’s time to stand up and take a break, and it will automatically power down when it senses that you’ve left. Jason Fagone
When you aim the SpeechJammer at someone, it records that person’s voice and plays it back to him with a delay of a few hundred milliseconds. This seems to gum up the brain’s cognitive processes — a phenomenon known as delayed auditory feedback — and can painlessly render the person unable to speak. Kazutaka Kurihara, one of the SpeechJammer’s creators, sees it as a tool to prevent loudmouths from overtaking meetings and public forums, and he’d like to miniaturize his invention so that it can be built into cellphones. “It’s different from conventional weapons such as samurai swords,” Kurihara says. “We hope it will build a more peaceful world.”Catherine Rampell

Researchers at Wharton, Yale and Harvard have figured out how to make employees feel less pressed for time: force them to help others. According to a recent study, giving workers menial tasks or, surprisingly, longer breaks actually leads them to believe that they have less time, while having them write to a sick child, for instance, makes them feel more in control and “willing to commit to future engagements despite their busy schedules.” The idea is that completing an altruistic task increases your sense of productivity, which in turn boosts your confidence about finishing everything else you need to do.

A team of Dutch and Italian researchers has found that the way you move your phone to your ear while answering a call is as distinct as a fingerprint. You take it up at a speed and angle that’s almost impossible for others to replicate. Which makes it a more reliable password than anything you’d come up with yourself. (The most common iPhone password is “1234.”) Down the line, simple movements, like the way you shift in your chair, might also replace passwords on your computer. It could also be the master key to the seven million passwords you set up all over the Internet but keep forgetting.Chris Wilson

What innovation scares you the most these days?
The Internet is not merely connecting computers together for the benefit of humans; it’s connecting humans together to reinvent labor. This opens terrific opportunities along with real worries. Soon we’ll have to question whether an earnest-looking group of protesters with hand-lettered signs is genuine or simply rapidly convened as a paid flash mob: a crowdsourced crowd. We’ll be able to one-click shop for cheering throngs or protests at a particular location on a moment’s notice, indistinguishable from genuine collective sentiment. A house can be surveilled and a spouse tailed because an online bounty has been put out for anyone nearby to take a photo of the building at a particular address, or to “follow that car.”
Two Norwegian psychologists think that modern playgrounds are for wimps. Instead of short climbing walls, there should be towering monkey bars. Instead of plastic crawl tubes, there should be tall, steep slides. And balance beams. And rope swings. The rationale is that the more we shield children from potential scrapes and sprained ankles, the more unprepared they’ll be for real risk as adults, and the less aware they’ll be of their surroundings. Leif Kennair and Ellen Sandseter’s ideas have won the support of playground experts on both sides of the Atlantic; one company, Landscape Structures, offers a 10-foot-high climbing wall that twists like a Möbius strip.

What’s the new psychological trick for improving performance? Strategic lying. When amateur golfers were told, falsely, that a club belonged to the professional golfer Ben Curtis, they putted better than other golfers using the same club. For a study published in March, human cyclists were pitted against a computer-generated opponent moving at, supposedly, the exact speed the cyclist had achieved in an earlier time trial. In fact, the avatars were moving 2 percent faster, and the human cyclists matched them, reaching new levels of speed. Lying is obviously not a long-term strategy — once you realize what’s going on, the effects may evaporate. It works as long as your trainer can keep the secret.Gretchen Reynolds
On traditional roller coasters, your weight is centered over the wheels, but two new coasters — the X Flight at Six Flags Great America and Dollywood’s Wild Eagle — have you hanging off the side of the track, dangling in midair. It’s kind of like you’re sitting on the wings of a plane. The Swiss company Bolliger & Mabillard had to completely reimagine the seat design to handle the stress caused by the differently distributed weight. Cora Currier
Researchers at Imperial College London are closing in on a formula for a new kind of booze — synthetic alcohol, it’s called — that would forever eliminate the next morning’s headache (not to mention other problems associated with drinking). The team, led by David Nutt, a psychiatrist and former British drug czar, has identified six compounds similar to benzodiazepines — a broad class of psychoactive drugs — that won’t get you rip-roaring drunk but will definitely provide a buzz. According to Nutt, the alcohol substitute would be a flavorless additive that you could put in a nonalcoholic drink. And when you want to sober up, all you’d have to do is pop a pill. Clay Risen

What tech problem needs to be addressed most urgently?
That we’re heading for a bandwidth crunch. We’re saddling the Internet with amazing new features — movies on demand, streaming TV, Siri voice recognition, whole-house backup — but they’re starting to overwhelm the existing Internet’s capacity, especially on cellular networks. The Internet and phone companies respond by imposing monthly limits, and the F.C.C. is trying to make more wireless frequencies available. But unless something gives, “high-speed Internet” will soon become an oxymoron. You’ll just have to get used to pauses in your streaming video.
In February, Chaotic Moon Labs began testing a robotic shopping cart that acts a bit like a mind-reading butler. To start it up, you can text message the cart’s built-in tablet computer. Now it knows who you are and what you need for dinner. The cart uses Microsoft’s Kinect motion-sensor technology to track and follow you through the store, pointing you — in a synthy voice reminiscent of a G.P.S. navigator — toward products on your list. The system will also warn you if you’ve added something that violates your dietary restrictions. Still only a prototype, the cart isn’t nearly as nimble as its human-powered cousin, but it does have one main advantage. Items you add to the cart can be automatically scanned, and you can finalize your purchase from the device, skipping the checkout line entirely. Farhad Manjoo

Scientists at Princeton and Tufts are working on a superthin tooth sensor (a kind of temporary tattoo) that sends an alert when it detects bacteria associated with plaque buildup, cavities or infection. It could also notify your dentist, adding an extra layer of social pressure to make an appointment. The sensor may have wide-ranging use: the researchers have already used it to identify bacteria in saliva associated with stomach ulcers and cancers. While the sensor won’t last long on the surface of a well-brushed and flossed tooth, Michael McAlpine, the project’s leader, says that the sensors will be inexpensive enough that you can replace them daily.

Wearing a small sensor on your head, at home, while you sleep, could be the key to diagnosing diseases early and assessing overall health. “This tech,” says Dr. Philip Low, the founder of a medical technology firm called NeuroVigil, “enables us to look for faint signals of, say, schizophrenia, Parkinson’s, depression or Alzheimer’s in the brain, even though there may be no obvious symptoms.” Thus far, Low’s device has found a number of applications: evaluating children with autism, studying the efficacy of trial-phase drugs and assessing traumatic brain injury in soldiers. Currently, Low is working on a newer version of the device, which will be the size of a quarter and will transmit brain scans directly to smartphones and tablet computers. “We’re using sleep,” Low says, “as the gateway to the brain.” Howie Kahn

What innovation are you clamoring for?
What I’d really love to see is full genomic sequencing at moderate costs that individuals can do at home. When taking a given drug or even deciding what to eat or how much to exercise, wouldn’t it be good to know what you really need to be concerned about and what you don’t? If you had high cholesterol, you could know if you should really be taking a statin, which, based on your particular genomics, could have limited benefit and some associated risk.
This year, Eva Redei, a professor at Northwestern’s Feinberg School of Medicine, published a paper that identified molecules in the blood that correlated to major depression in a small group of teenagers. Ridge Diagnostics has also started to roll out a test analyzing 10 biomarkers linked to depression in adults. “Part of the reason there’s a stigma for mental illness, including depression, is that people think it’s only in their heads,” Redei says. “As long as there’s no measurable, objective sign, we’re going to stay in that mind-set of ‘Just snap out of it.’ ” Blood tests will take mental illness out of the squishy realm of feelings. And as Lonna Williams, C.E.O. of Ridge Diagnostics, says, they’ll help people understand “it’s not their fault.”

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard are working on a technology that would make household cleaning supplies much smarter — almost like a sprayable forensics team. When the spray hits a surface where there are pathogens present, like your bathroom sink, it would bind to the bad stuff and turn a color — orange, say, for E. coli. Then you could knock it out with a stronger disinfectant.Nathaniel Penn

You need a lot of water to put out a sizable blaze, and the chemicals used in fire extinguishers can be toxic (halons, the most effective chemical fire suppressant, create holes in the ozone layer). So the Defense Advanced Research Projects Agency at the Pentagon has developed a hand-held wand that snuffs out fires, without chemicals. According to the program’s manager, Dr. Matt Goodman, an electric field destabilizes the flame’s underlying structure rather than blanketing the fire to smother it. Eventually, the technology could be used to create escape routes or extinguish fires without damaging sensitive equipment nearby.

Frozen food may soon be on par with anything you can get at a three-star restaurant. Sous vide — a process in which food is heated over a very long period in a low-temperature water bath — has been used in high-end restaurants for more than a decade. (Thomas Keller and Daniel Boulud were early proponents.) But the once-rarefied technique is becoming mass market. Cuisine Solutions, the company that pioneered sous vide (Keller hired it to train his chefs), now supplies food to grocery stores and the U.S. military. Your local Costco or Wegmans may sell perfectly cooked sous vide lamb shanks, osso buco or turkey roulade. Unlike most meals in the freezer aisle, sous vide food can be reheated in a pot of boiling water and still taste as if it were just prepared. And because sous vide makes it almost impossible to overcook food, it’s perfect for the home cook. Fortunately, sous vide machines are becoming more affordable. “It’s like the microwave was 30 years ago,” Keller says. Michael Ruhlman

It’s depressing to think how much food packaging there is in your kitchen right now — all those juice cartons, water bottles and ice-cream containers. But what if you could eat them? “We’ve got to package in the same way nature does,” says a Harvard bioengineer named David Edwards. And so he has devised a way to convert foods into shell-like containers and films that he calls Wikicells. Yogurt will be encased in a strawberry pouch, for instance. You could wash and eat the packaging, like the skin of an apple, or you could toss it, like the peel of an orange, since it’s biodegradable. The newly wrapped ice cream and yogurt will be available later this month at the lab store in Paris, with juice and tea coming within the next year or two.

Rather than spray water, fertilizer and pesticides across their fields, many industrial farms are taking a more targeted approach, using wireless soil sensors and G.P.S.-enabled equipment to determine which spots need the most attention. Soon, you’ll be able to use similar technology in your front yard. The home landscaping company Toro already has a line of consumer-grade moisture sensors that turn on the sprinkler system when your lawn is dry. It’s a good start, but Sanjay Sarma, of the Field Intelligence Lab at M.I.T., is working to produce tiny, inexpensive sensors that you scatter across your lawn by the dozens and that will track everything from bug infestations to mineral deficiencies. Then they’ll tell you what to do about it: three spritzes of pesticide to the tomato plants, stat.

Petting a living animal has long been known to lower blood pressure and release a flood of mood-lifting endorphins. But for various reasons — you’re at work, or you’re in a hospital, or your spouse is allergic to dogs — you can’t always have a pet around to improve your mental health. So researchers at the University of British Columbia have created something called “smart fur.” It’s weird-looking (essentially just a few inches of faux fur) but its sensors allow it to mimic the reaction of a live animal whether you give it a nervous scratch or a slow, calm rub. Creepy? Yes. But effective. Clay Risen

Researchers at Merck have created a pill called suvorexant that essentially makes you a narcoleptic for a night. It turns out that might be the best cure for insomnia. Unlike existing sleep aids, the drug (which will likely be reviewed by the F.D.A. later this year) works by turning off wakefulness rather than by inducing sleep. “There’s good reason to believe this pill brings on more R.E.M. sleep and better rest,” says Dr. Emmanuel Mignot of Stanford University. “It’ll be less of a hammer on the brain.” Howie Kahn

Is there any invention you find particulary sinister?
A smaller, even stealthier drone — something called the Cyberbug Drone, currently under development. In this model, a microsystem is embedded in an insect larva, and when the adult emerges — whether bee, butterfly or ant — a “bug” really will be a bug, and the proverbial fly on the wall will be actual. Tiny winged avengers can hunt down invasive beetles, cabbage whites can snoop on destructive raccoons and six-legged nanospies can insert themselves into the air-conditioning systems of even the most impenetrable buildings. As for bedbugs, they’ll wedge themselves under mattresses to snoop on errant spouses. The hive mind really will be the hive mind! Coming soon to a crevice near you.
