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.

Solved a problem thus restoring my power to some areas of my house

Had a number of outlets not working and lost AC in 97 degree weather--he came twice the 1st time approx 1hr 20 minutes--wasn't able to locate problem---this I put on myself as I was unaware of putting a breaker box behind a vanity that hadn't been move since purchase of my house. Second visit after some search found problem 1hr

OK the skinny--I think he was professional--on time

Was upfront on costs

Problem once the second box was located was an easy fix so thought a touch high on price--that said it was upfront and had I had the answer to location as I should have I think the billing would be much lower so will put this on myself. In other words I don't think he would have ripped me off

Bonus was after having 4 others trying to blame AC and being told I needed a new one---he said everything in my problems was electrical--and viewing my AC said it was fine--no need of new unit--for the moment if right saving me $$$$

Aubrey upgraded our electrical fuse panel, put in an updated outside service panel, replaced the main service line from the outside panel to the inside fuse box, and installed several outlets. His original estimate was complete and accurate. He brought our electrical system up to code and made several recommendations for changes and upgrades that we had not thought of. He worked with our schedule, was on time and very professional, and left our home as clean as when he arrived. He was extremely conscientious and reliable. We very highly recommend John's Electric and will definitely use them again.
