The device placed on the fingertips generates electricity from sweat – it works even when sleeping


Engineers at the University of California’s San Diego unit have created a fingertip device that generates small amounts of electricity using sweat. The best part of the new wearable technology is that the device is able to generate electricity even when the user is sleeping.

This type of sweat-generating device is a research-leading nanotechnology doctoral student Lu Yinin according to the first of its kind. Unlike other sweat-powered devices, this innovation does not require sports or other physical performance from the user to generate electricity.

Although the technology sounds very futuristic, the development of biofuel cells dates back to the 1960s, The Debrief says. The University of San Diego laboratory has been developing a variety of sweatable wearable biofuels for a decade. However, according to Yin, the previous devices are more intended for sports use.

The new device for collecting energy produces more electricity from light presses. Any activity that requires such movement, such as writing or playing the piano, can be a natural source of energy. The purpose of wearable technology is ultimately to act completely on its own behalf for the user.

The fingertips have been chosen as the location of the device, as they can produce 100-1000 times more sweat than other body parts. Instead of evaporating, the device collects sweat from the fingertips and can generate a significant amount of energy. According to the study, after a 10-hour night’s sleep, the device collected almost 400 millijoules of energy, which is enough for a wristwatch, for example, all day long.

According to Yin, the purpose of the device is to be practical, and the device can be used to bring electricity to sensors and monitors, for example. However, the launch of the device still requires the development of compatible low-power devices.
