SRI is developing wearable “exosuits” that can augment the musculoskeletal system for performance and strength enhancement and assistance to overcome or prevent damage from injury or disease. SRI’s exosuit differs from exoskeletons by using new muscle-like actuation, comfortable and soft skin attachment, and electronically releasable spring elements to minimize mass, bulk, and noise as well as eliminate constraints on natural joint motions. As part of DARPA’s Warrior Web Program, the technology is being applied to prevent and reduce musculoskeletal injuries caused by dynamic events typically found in the warfighter’s environment. They are exploring other military applications and beginning to use the technologies to assist individuals with musculoskeletal diseases.
The wearable exosuit, Superflex, uses motion sensors, accelerometers and gyroscopes to read the speed and angles of the owner’s legs and adjust its movements accordingly.
Intel is in the midst of its biggest business transition ever. Just a few months ago, the chip giant announced that it would be laying off 11,000 workers and taking a step away from the PC market. Instead, it’ll be focusing on wearables and IoT devices. Coinciding with those announcements was an executive shuffle that put Navin Shenoy, its Mobile Client VP, in charge of its wider Client Computing Group (which covers all consumer devices). At Computex this week, we had a chance to pick Shenoy’s brain about Intel’s path forward.
What do you envision being the next major breakthrough for PC form factor?
We’re working on lots of things that are mind-blowing. To me, we have to figure out how to get to J.A.R.V.I.S. [Iron Man’s trusty AI, not Intel’s vaporware earpiece]. The ability to manipulate things wherever you are, look at things wherever you are, talk to things in a more natural way. That’s the next big breakthrough in computing. And it will be in so many domains, it won’t just be PCs. It’ll be phones, tablets and also new types of things we haven’t conceived of yet.
Walk into any workout facility and, odds are, you’ll see plenty of people working with a personal fitness trainer. It’s common practice to hire a trainer who can help improve your physical fitness, but is it possible to find a trainer for better mental fitness? Entrepreneur Ariel Garten founded her company, InteraXon, around this very idea. Bolstered by new advances in non-invasive brain-machine interfaces (BMIs) that can help people practice ways to reduce stress and improve cognitive abilities, Garten believes this is just the beginning of a lucrative industry.
Garten’s company manufactures a BMI called the Muse, an EEG sensor headband that monitors occipital and temporal brain waves. According to Ariel, the goal of the device is to help people understand their mental processes while at the same time learning to calm and quiet their mind at any time, with the same convenience of carrying around an iPhone.

“We don’t measure stress (with the Muse). What we’re actually measuring is a state of stable, focused attention,” Garten said. “When you hone your mind into a state of stable focused attention, what you’re able to do is resist the thoughts that you have and the distractions that you have. That helps you improve your cognitive function and attention. And, it also helps you decrease your stress, anxiety and all of the downstream physiological responses of that stress.”
According to Garten, when one is in a state of stable, focused attention, their brain-wave signatures are very similar to those seen when one is in a calm, relaxed state. Reaching that state of stable, focused attention leads to more Alpha waves, which have been recorded when people do activities like preparing to go to bed. Those Alpha waves represent a shutting down of external sensory processing, which Ariel says amounts to better holding your focus.
While it has parallels to meditation, Garten noted that BMI-based stable attention exercises can show one’s brain activity in real time. That feedback allows for deeper and faster learning, as well as the ability to maintain the practice or the exercise over time.
Much like the concept of muscle memory, once a user learns how to reach stable, focused attention, the Muse and its accompanying applications help train the user to be able to return to that state whenever it’s needed in their daily lives. Garten noted that a number of research studies have found focused attention exercises can also lead to increased gray matter in the brain, while decreasing anxiety and helping with depression, eating disorders, insomnia and more.
“In the next five years, you’re going to see a proliferation of these types of devices… simple clean, and easy-to-use brain sensing technology applications. What you’ll see is applications that let you play games directly with your mind and applications that let you understand and improve yourself,” she said. “We’re not at the point in technology where you can control stuff directly with your mind by reading a thought. That will happen someday…15 to 20 years in the future.”
While we can look at changes at brain states right now, the future promises more responsive technology that can help provide you with a much more detailed understanding of your brain’s function and use that information to support your interactions with your external environment.
“We’re going to be able to see applications and algorithms that understand you more effectively and are able to give you personalized insight based on you and your own brain and how it works, moment to moment to moment,” Garten said. “We’re going to see the hardware getting smaller, so that it fits into other devices you already wear. We’re also going to also see greater accessibility and cross platform integration with your favorite tools to get a more comprehensive picture of yourself.”
BMI technology that is minimally invasive but offers the user more personalized control certainly seems like a pragmatic first step towards broader acceptance of such technologies in the near future. While not part of the mainstream consumer market quite yet, Muse’s successes with its loyal customer base may point to real opportunity for similar products in the neurotechnology marketplace.
Make no mistake, today’s wearables are clever pieces of kit. But they can be bulky and restricted by the devices they must be tethered to. This has led engineers to create thinner and more powerful pieces of wearable technology that can be applied directly to the skin. Now, researchers at the University of Wisconsin-Madison, led by Zhenqiang “Jack” Ma, have developed “the world’s fastest stretchable, wearable integrated circuits,” that could let hospitals apply a temporary tattoo and remove the need for wires and clips.
With its snake-like shape, the new platform supports frequencies in the .3 gigahertz to 300 gigahertz range. This falls in what is set to become the 5G standard. For a mobile phone, 5G enables faster speeds and greater coverage, but with epidermal electronics, engineers have discussed the possibility that wearers could transmit their vitals to a doctor without having to leave their home.
While the idea isn’t unique, the integrated circuits created by Ma and his team have a much smaller footprint than those developed by other researchers. Earlier transmission lines can measure up to 640 micrometers (or .64 millimeters), but UW–Madison’s solution is just 25 micrometers (or .025 millimeters) thick. The Air Force Office of Scientific Research also supports Ma’s research, suggesting that his wearable breakthroughs may help pilots of the future.
Bionic Power makes wearable technology for charging batteries. Today, we are focused on developing our PowerWalk® Kinetic Energy Harvester for military use and will begin multi-unit field trials with the U.S. Army and U.S. Marine Corps next year. In the future, we see our walk-recharge technology being used in disaster zones and remote worksites, and by consumers in recreational, emergency preparedness and backup applications.
The consumer marketplace is flooded with a lively assortment of smart wearable electronics that do everything from monitor vital signs, fitness or sun exposure to play music, charge other electronics or even purify the air around you — all wirelessly.
Now, a team of University of Wisconsin—Madison engineers has created the world’s fastest stretchable, wearable integrated circuits, an advance that could drive the Internet of Things and a much more connected, high-speed wireless world.
Led by Zhenqiang “Jack” Ma, the Lynn H. Matthias Professor in Engineering and Vilas Distinguished Achievement Professor in electrical and computer engineering at UW–Madison, the researchers published details of these powerful, highly efficient integrated circuits today, May 27, 2016, in the journal Advanced Functional Materials.
Engineers at the University of California San Diego have developed the first flexible wearable device capable of monitoring both biochemical and electric signals in the human body. The Chem-Phys patch records electrocardiogram (EKG) heart signals and tracks levels of lactate, a biochemical that is a marker of physical effort, in real time. The device can be worn on the chest and communicates wirelessly with a smartphone, smart watch or laptop. It could have a wide range of applications, from athletes monitoring their workouts to physicians monitoring patients with heart disease.
Nanoengineers and electrical engineers at the UC San Diego Center for Wearable Sensors worked together to build the device, which includes a flexible suite of sensors and a small electronic board. The device also can transmit the data from biochemical and electrical signals via Bluetooth.
Nanoengineering professor Joseph Wang and electrical engineering professor Patrick Mercier at the UC San Diego Jacobs School of Engineering led the project, with Wang’s team working on the patch’s sensors and chemistry, while Mercier’s team worked on the electronics and data transmission. They describe the Chem-Phys patch in the May 23 issue of Nature Communications.
Designed by fashion icon Iris Apfel, the Wisewear Activity Tracker can count your steps taken, distance travelled, calories burned and more in style. You can even call for help in an emergency just by tapping the device.
The physical limitations of existing materials are one of main problems when it comes to flexible electronics, be it wearables, medical or sports tech. If a flexible material breaks, it either stays broken, or if it has some self-healing properties it may continue to work, but not so well. However, a team from Penn State have creating a self-healing, flexible material that could be used inside electronics even after multiple breaks.
The main challenge facing researchers led by Professor Qing Wang, was ensuring that self-healing electronics could restore “a suite of functions”. The example used explains how a component may still retain electrical resistance, but lose the ability to conduct heat, risking overheating in a hypothetical wearable, which is never good. The nano-composite material they came up with was mechanically strong, resistant against electronic surges, thermal conductivity and whilst packing insulating properties. Despite being cut it in half, reconnecting the two parts together and healing at a higher temperature almost completely heals where the cut was made. The thin strip of material could also hold up to 200 grams of weight after recovering.
