Amazing new technology powers wearable devices with our own sweat.

A team of engineers from the University of California, San Diego has developed remarkable stretchable power cells that take energy from your own sweat and power electronics, like LEDs and even Bluetooth radios! New technology powers devices with sweat
For a field that has been struggling to come up with devices that are powerful enough and stretchable enough, these epidermal biofuel cells are a major breakthrough. The breakthrough was achieved thanks to a combination of extremely clever chemistry, highly advanced materials and electronic interfaces. This combination let them build a highly stretchable, electronic foundation using lithography and screen-printing to manufacture 3D carbon nanotube-based cathode and anode arrays.
The biofuel cells are equipped with an enzyme that oxidizes the lactic acid present in human sweat to generate current. This turns the sweat into a source of power. Because the concentration of lactic acid in a person's sweat gets diluted over time, the team is exploring a way to store the energy produced while the concentration of lactate is high enough and then release it gradually.So future work is needed before this technology can be considered a full success.

What others say about John's Electric Service

This company did an incredible job on our house. Had a few issues to get home ready for sale and he came next day - completed everything with perfection and great price. Aubrey is very honest and trustworthy! Will use him any other time I need electric work and strongly recommend him

Mr. Teele arrived quickly, diagnosed our outage problem and fixed it that same afternoon. We have an older electrical system that many other electricians simply won't work with. But Mr. Teele confidently made repairs and even called to check on us the next day to ensure all was working well.

I was very satisfied with the service. I drilled a hole in my main service line on a holiday, and they had me up and running the same afternoon. Thanks!!

Service was above and beyond excellent. Stuck with us and the power company until the true root of the problem was found. Worked around our schedule and budget restraints. Left things clean and was very respectful. Would definitely recommend him and use him again.
