Battery can run on tears, sweat
    2017-August-16  08:53    Shenzhen Daily

Scientists have developed a flexible battery* that could run on saline solutions* such as bodily fluids like tears, sweat or even urine.

A new paper by researchers at Fudan University in Shanghai proposes a new technique for manufacturing batteries that would replace toxic chemicals with salt water.

The batteries could provide a safer way to power wearable or implanted devices, according to the paper published in the journal Chem.

Batteries typically consist of positive and negative electrodes* separated by an electrolyte*.

“Most existing energy storage systems are based on strong corrosive* or toxic electrolytes, posing a huge safety hazard as a result of solution leakage,” the study authors write.

The research proposes two forms of flexible batteries: one shaped like a piece of tape with the electrodes separated by a thin sandwich layer, and one shaped like a thread with two nano-tube* electrodes inside.

The scientists said soduim sulfate*, a nontoxic chemical often used in detergents*, worked best as an electrolyte. But they added that a simple saline solution, or salt water like that of bodily fluids, also performed well. That could make the batteries ideal for implanted devices.(SD-Agencies)
