UW researchers develop a stretchable, wearable device that lights up an LED using only the warmth of your skin
University of Washington researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient — it still functions even after being pierced several times and then stretched 2,000 times.
Finger wrap uses sweat to provide health monitoring at your fingertips—literally
A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid. UC San Diego engineers have developed an electronic finger wrap that monitors vital chemical levels—such as glucose, vitamins, and even drugs—present in the same fingertip sweat from which it derives its energy.
How Your Sleep Patterns Change Can Tell You About Your Health
Your sleep tracker might give you information about more than just your sleep–specifically, it might give you information about chronic conditions such as diabetes and sleep apnea, and illnesses such as COVID-19. This is one of the findings of a study that analyzed data from 5 million nights of sleep across roughly 33,000 people.

Single-lead ECG tracings from an Apple Watch interpreted by an artificial intelligence (AI) algorithm developed at Mayo Clinic effectively identified patients with a weak heart pump.
Real-time flood sensors, urban farms, autonomous cars, dancing drones and more at NYU Tandon’s Research Excellence Exhibit
The NYU Tandon School of Engineering will showcase over 40 innovative and future-forward research projects by faculty and students, along with interactive, family-friendly tech activities, at its 2022 Research Excellence Exhibit.The annual expo, in its ninth year, takes place on Friday, April 29, 1:00 p.m. to 4 p.m.
Calling all couch potatoes: this finger wrap can let you power electronics while you sleep
A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it. What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still.
NUS engineers devise novel approach to wirelessly power multiple wearable devices using a single source
Researchers from NUS have come up with a way to use one single device – such as a mobile phone or smart watch – to wirelessly power up to 10 wearables on a user. This novel method uses the human body as a medium for transmitting power. Their system can also harvest unused energy from electronics in a typical home or office environment to power the wearables.
‘Wearable microgrid’ uses the human body to sustainably power small gadgets
This shirt harvests and stores energy from the human body to power small electronics. UC San Diego nanoengineers call it a “wearable microgrid”—it combines energy from the wearer’s sweat and movement to provide sustainable power for wearable devices.

A flexible screen-printed rechargeable battery with up to 10 times more power than state of the art
A team of researchers has developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured in sterile conditions, under vacuum, this one can be screen printed in normal lab conditions. The device can be used in flexible, stretchable electronics for wearables as well as soft robotics.
Clothing, Tattoos Could Be Used to Monitor Patient Health
A shirt that monitors your blood pressure or a pair of socks that can keep track of your cholesterol levels might be just a few years away from becoming reality.
