Tattoo That Harvests Energy from Persperation

Power through perspiration. That is the idea behind the new temporary tattoo that can store and generate electrical energy from your own sweat.

This new method was announced at the American Chemical Society meeting by Dr. Wenzhao Jia of the University of California, San Diego.

According to Jia’s explanation of the device in the journal Angewante Chemie, the temporary tattoo essentially acts as a sensor that measures the body’s lactate levels, which are the chemicals naturally present in sweat. From there, an enzyme in the sensor strips electrons from, which generates an electrical current. The current is then stored in a battery that is also built into the sensor.

Using Hemp to Store Energy

“People ask me: why hemp? I say, why not?”

That is what Dr. David Mitlin said about the new discovery in bio-waste that has been published in the journal ACS Nano, according to BBC.

Mitlin and his team presented their findings at the American Chemical Society meeting in San Francisco, where it was explained how waste fibres from hemp can be transformed into high performance energy storage devices.

The hemp – which is legal to grow due to the absence of THC – is producing supercapacitors that are at least on par with the graphene, which is known to be the industry’s gold standard.

Dr. Mitlin and his researchers primary focusing on taking produces that are considered waste and evolving them into something applicable and with high value.

This from BBC:

But the leftover bast fibre – the inner bark – typically ends up as landfill. Dr Mitlin’s team took these fibres and recycled them into supercapacitors – energy storage devices which are transforming the way electronics are powered.
