Got a hot body? Now you can charge your device


One of the biggest wearable bugbears, in my opinion, is the constant need to charge a smartwatch or fitness tracker every few days. Luckily, a new research project from North Carolina State University has shown a possible way to charge wearables without having to take them off everyday.

The researchers, led by associate professor of electrical and computer engineering, Daryoosh Vashaee, developed a new design for harvesting body heat and converting it into electricity.

“Wearable thermoelectric generators (TEGs) generate electricity by making use of the temperature differential between your body and the ambient air,” said Vashaee. “Previous approaches either made use of heat sinks—which are heavy, stiff and bulky—or were able to generate only one microwatt or less of power per centimeter squared (µW/cm2). Our technology generates up to 20 µW/cm2 and doesn’t use a heat sink, making it lighter and much more comfortable.”

NCSU integrated the technology into a t-shirt, which provide 16 µW/cm2 when the wearer is active. That could open the door to health tracking inside smart clothes, powered directly from a user’s activity.

But really, is being hot enough?

The power generation, while significant compared to past results, is still not enough for most devices. Some low-power sensors might be able to get by with the juice from a human body, but for wearables that track a multitude of things, there isn’t enough energy conversation available in the current design.

The researchers believe the new technology can generate more electricity, if the size of the material is enlarged. Currently, the material is 1cm2, but a smart clothes manufacturer could potentially fit larger amounts of the material onto a t-shirt or jacket; the manufacturer might also make the material thicker to capture more heat.

We are still far off a Matrix world where a human body can power a machine empire, but NCSU is taking the first steps to what could be a charge free world.

Are police body cameras collecting too much data?


Police body cameras are starting to become a necessity to stop the surge in complaints from U.S. citizens, who want law enforcement to be more accountable and reduce the violence committed by officers.

In Rialto, California, a study by Barak Ariel, a experimental criminology lecturer at the University of Cambridge showed that body cameras reduce complaints by 87 percent and use of force dropped by 59 percent.

Even with this huge drop in animosity between law enforcement and citizens in the city, Taser, the creator of the body cameras, believes there is more to be done to make the system better and more efficient.

Trevin Chow, director of product management at Taser, said that smart technology is necessary to sift through the massive amounts of data being accumulated by all of the police cameras.

Speaking at the Wearable Technologies show in San Francisco, Chow revealed that Taser stores 3.5 petabytes (one million gigabytes) of data and a file is uploaded every 12 seconds to its database. That’s with only 30 cities in the U.S. adopting the camera tech.

For this data to be useful, Taser needs to create systems to single out issues that need addressing. It has plans to trigger cameras to take videos when a police officer steps outside a car, removes a shotgun from the rack, or turns a Taser on, which should provide law enforcement overseers with indications of action in the field.

Taser is also working on machine learning and language processing programs to make recognizing excessive use of force or aggressive interactions with the public even easier for overseers.

“We’re investing in more than just a camera. We’re looking at computer vision, natural language processing, and machine transcription to really look at this area, to see how effective we can make these solutions. We need to offer more than cameras to make communities safer,” said Chow at the event.

It is a difficult balance for law enforcement between reducing incidents involving excessive use of tasers and police brutality, and making officers feel like they’re the bad guys. Cameras seem like a good way forward, but the future Taser is proposing might be too much for some in the force.

Will NBA spotlight boost SubPac’s full body wearable?


Cleveland Cavaliers point guard Kyrie Irving showed off a full-body wearable at the NBA Finals press conference, hours before the final match against the Golden Gate Warriors. And it could give the wearable’s maker, SubPac, the marketplace’s championship crown.

The wearable in question provides “tactile sound” that allows you to feel music or sound throughout your entire body.

Irving didn’t mention if he is partnered with SubPac, only saying to press “you’ll be hearing about it soon.” It may be possible he was using the wearable during training, though for what purpose, we don’t know.

The SubPac that Irving wore is different to the product in the startup’s YouTube video, posted in late 2015. That may be what Irving was referring to when he hinted at news coming soon; a new version with enhancements and a new design.

If Irving is the poster boy for SubPac, we suspect the new version may have some sports-related functionality, like simulated force while shooting or dribbling in training.

SubPac currently aimed at music and VR

The current SubPac is marketed at music and virtual reality, both can utilize biometrics to provide a full body experience. SubPac also has a body wearable for people sitting down, the S2, which could be more useful for video gamers.

Some video game firms have delved into biometrics in the past, including Half Life and Portal developer Valve. In an interview with The Verge, Valve director Gabe Newell said:

“We think that, unlike motion input where we kind of struggled to come up with ideas, [there’s potential in] biometrics.We have lots of ideas.”

With the first Steam VR headset, the HTC Vive VR, launched earlier this year, we may see Valve’s first attempts at biometric feedback in game. Other developers are looking into the effects biometrics can have on gameplay, like changing a level depending on the player’s heart-rate.

Full body wearables that provide vibration could be valuable in other areas, including training simulations for firefighters, police officers, and soldiers. SubPac has not mentioned any of these areas as potential market, sticking with the music focus for its current wearables.
