cry me a river! scientists develop a flexible battery that can run on tears, sweat or even urine - ess energy storage system

Scientists have developed a flexible battery that can operate in saline solutions such as body fluids such as tears, sweat and even urine.
A new paper published Thursday by researchers at Fudan University in Shanghai, China, proposes a new technology for making batteries that will replace toxic chemicals with salt water.
A paper published in the journal chempros says batteries can provide safer power for wearable or implant devices.
The battery is usually composed of positive and negative electrodes separated by electrolyte.
The authors wrote that most existing energy storage systems are based on highly corrosive or toxic electrolyte, which can cause huge potential safety hazards due to solution leakage.
This study proposes two forms of flexible batteries: one shaped like a tape, the electrode is separated by a thin sandwich layer, and the other shaped like a threat, with two nano-cells
Electrode in the tube.
Scientists say a non-
Toxic chemicals often used in detergents, as the best electrolyte effect.
But they added that a simple brine solution, or a brine like a body fluid, also performed well.
This may make the battery an ideal choice for implant devices.
