Finger Wrap uses Sweat to provide Health Monitoring at your Fingertips

A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid. Engineers at the University of California San Diego 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.

The advance was published Sept. 3 in Nature Electronics by the research group of Joseph Wang, a professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at UC San Diego.

The device, which wraps snugly around the fin...

No batteries? No sweat! Wearable Biofuel Cells now produce Electricity from Lactate

No batteries? No sweat! Wearable biofuel cells now produce electricity from  lactate | EurekAlert! Science News

Scientists develop biofuel cells that can power wearable electronics purely by using human sweat. Wearable electronic devices and biosensors are great tools for health monitoring, but it has been difficult to find convenient power sources for them. Now, a group of scientists has successfully developed and tested a wearable biofuel cell array that generates electric power from the lactate in the wearer’s sweat, opening doors to electronic health monitoring powered by nothing but bodily fluids.

It cannot be denied that, over the past few decades, the miniaturization of electronic devices has taken huge strides...

‘Tequila’ powered Biofuels more Efficient than Corn or Sugar

Ethanol from agave could be used for transport fuel and hand sanitizer. The agave plant used to make tequila could be established in semi-arid Australia as an environmentally friendly solution to Australia’s transport fuel shortage, a team of researchers at the University of Sydney, University of Exeter and University of Adelaide has found.

The efficient, low-water process could also help produce ethanol for hand sanitiser, which is in high demand during the COVID-19 pandemic.

In an article published this week in the Journal of Cleaner Production, University of Sydney agronomist Associate Professor Daniel Tan with international and Australian colleagues have analysed the potential to produce bioethanol (...
