Stretchable biofuel cells extract energy from sweat

Stretchable biofuel cells extract energy from sweat
A team of engineers has developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. The biofuel cells generate 10 times more power per surface area than any existing wearable biofuel cells. The devices could be used to power a range of wearable devices. The epidermal biofuel cells are a major breakthrough in the field, which has been struggling with making the devices that are stretchable enough and powerful enough.

3M improves adhesion of wearable medical devices

3M improves adhesion of wearable medical devices
When Joe’s heart-rate monitor kept falling off, he asked his doctor, “Isn’t there a better way to make it stick?” Thanks to 3M, there is. The company that makes everything from Post-it® Notes to structural adhesives that hold airplanes together, also makes advanced medical adhesives that can hold for up to two weeks. When considering adhesive science and the challenges of a substrate like skin, design engineers know sticking-to-skin is trickier than you would think.

"Alexa, let's walk to the kitchen"

"Alexa, let's walk to the kitchen"
Bionik Laboratories has announced it has integrated Amazon's Echo technology and Alexa Voice Service into its ARKE lower body exoskeleton. The ARKE exoskeleton utilises Bionik's proprietary transmission and actuation system, making it one of the most powerful robotic devices compared to similar systems. It will now include device control, utilising multiple sensors located throughout the device in combination with Alexa.

Battling dehydration with wearables and big data

Battling dehydration with wearables and big data
  Dehydration is one of the most common causes of death among young children in the developing world – particularly during the hot summer months. ETH Professor Walter Karlen and his team of researchers have developed an inexpensive mobile device that could be used by laypeople to more effectively treat dehydration.

Smart underwear prevents back stress with just a tap

Smart underwear prevents back stress with just a tap
TV infomercials offer a world of potential solutions for back pain, but most of them have at least one of three problems — they’re unproven, unworkable or just plain unattractive. A team of Vanderbilt University engineers is changing that with a design that combines the science of biomechanics and advances in wearable tech to create a smart, mechanised undergarment. Their device gets its U.S. debut Aug. 8-11 at an American Society of Biomechanics conference in Boulder, Colorado.

Wearable helps improve balance in Parkinson's patients

Wearable helps improve balance in Parkinson's patients
University of Houston researchers in the Department of Health and Human Performance are helping patients with Parkinson's disease regain stable balance and confidence in performing daily activities in their own homes. A research team is developing the Smarter Balance System (SBS), a smartphone-based biofeedback rehabilitation system that guides patients through a series of balance exercises using wearable technology.

Robotic suit improves walking in stroke patients

Robotic suit improves walking in stroke patients
To help stroke patients regain their walking abilities, various robotics groups from industry and academia are developing powered wearable devices - so-called exoskeletons - that can restore gait functions or assist with rehabilitation. Historically, these systems restricted patients to a treadmill in a clinical setting, but in recent years portable systems have been developed that enable walking overground.

Colour-shifting electronic skin could optimise wearables

Colour-shifting electronic skin could optimise wearables
The ability of some animals, including chameleons, octopus, and squid, to change their skin colour for camouflage, temperature control, or communication is well known. While science has been able to replicate these abilities with artificial skin, the colour changes are often only visible to the naked eye when the material is put under huge mechanical strain.

Electronics allow long term on-skin health monitoring

Electronics allow long term on-skin health monitoring
  At the University of Tokyo in Japan researchers have developed a new method of producing stretchable electronics that are breathable, don’t irritate the skin, and weigh next to nothing. The development may lead to ubiquitous use of on-skin electronic sensors to monitor the body continuously in a variety of places and ways.

Low cost glove translates sign language

Low cost glove translates sign language
At the University of California San Diego engineers have developed a low-cost electronic glove capable of understanding sign language. A user simply puts it on and can sign away, with the glove wirelessly transmitting what it’s interpreting to another device to be read out or for the words to appear on a screen. The cost of all the parts comes out to less than $100, including the printed stretchable electronic sensors that are attached to the top of the fingers.
