Training sweat is common in gyms, but instead of sweat evaporates in the air in vain, you can take advantage of them to run smart phones.

According to Mashable, team leader Joseph Wang is leading the study using body sweat while jogging on computers to power electronic devices.

They invented a type of sensor on the erased tattoo, reacts with lactate, in the sweat and the circulatory system. The sensor takes away the electrons of lactate, enough to generate electricity and save on bio-batteries.

Currently, each sensor collects about 4 microwatts (mW) of electricity, while recent research shows that a smartphone is waiting for nearly 70mW of power for two minutes.

Experts are continuing to seek to improve the ability of the tattoo sensor.
