Your brutal gym workouts in the not-too-distant future could power your electronic devices.
In the latest of a series of exciting innovations unveiled at the meeting in San Francisco, scientists have presented a tattoo biobattery 聽after intense exercise.聽
“Our device is the first to use sweat. It’s a proof of concept,” said Dr. Wenzhao Jia of at the University of California, San Diego.
“At the moment, the power is not that high鈥攐nly four microwatts. But we are working on enhancing it so it can power small electronic devices.”
The team of researchers initially intended to develop a wearable lactate sensor, which they achieved by building one into temporary-tattoo paper.
“I’ve worn it myself; you don’t even feel it,”聽Jia聽. “It really is like a tattoo.”聽
Another layer of sophistication was added to the invention when Jia and her colleagues incorporated an enzyme capable of stripping electrons from secreted lactate, which generated a weak electrical current.
“A fit person is going to have to work out much harder to power the battery,” Jia explained.
The next step in the process is figuring out a way for this wearable biobattery to generate more electricity, possibly by making the strips more sensitive to lactate.
If all goes according to plan, you will eventually become your own renewable energy source. For better or worse.聽
