Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a soft and stretchable battery that is powered by human perspiration.

The prototype battery consists of printed silver flake electrodes that generate electricity in the presence of sweat. Measuring 2 cm by 2 cm and as flat as a small paper bandage

......

The battery could help reduce harmful electronic waste, as it does not contain heavy metals or toxic chemicals and the scientists behind it believe it could lead to innovation within the wearable tech industry.

As the stretchable textile used is very absorbent, it retains a lot of sweat, allowing the battery to remain powered even when the rate of sweating is inconsistent.

The device is also “more durable” than current technology, said Prof Lee, as the team has shown that it can withstand strain from a wearer’s daily activities and repeated exposure to stress or sweat.

The slimness of the battery additionally addresses two problems in wearable technology: It is sleeker and thus more attractive to consumers compared to traditional button batteries and it carries enough charge to last throughout the day, unlike current thinner batteries.

Associate Professor Irene Goldthorpe from the University of Waterloo’s Department of Electrical and Computer Engineering, who is not involved in the research, said the study may open a “new paradigm” in the design of wearable electronics.

“It is well-known that electronics do not like moisture and thus wearable devices are typically fully encapsulated to shield them from sweat,” she said, adding that the study turns sweat “from a hindrance into an asset”.

A patent application for the sweat-powered battery has also been filed through the university’s enterprise and innovation company, NTUitive.

Like that there might be a market and demand for sweat in future. Dunno pig's sweat and horse's sweat can or not.........

It is just a small invention, how to get Nobel prize...

Most likely good enough for a gimmick but just a flash in the pan.........

Unlikely lah. But could be very profitable.
