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

Thanks for Saving Me!

John's Electric was wonderful! I called and he was at my house within an hour!! I was at great risk of fire because of my breaker overheating, and he got me taken care of quickly, and affordably! I have a home warranty, that wouldn't cover my issue, and he jumped in and took care of me. If I ever had need again, I know who to call. Couldn't recommend John's any higher!!!

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.
