American chemists have successfully developed a soluble battery made of magnesium and paper intended for use in medical implants.
Wax was used for the encapsulation process. Thanks to the ability to choose the type and thickness of this coating, the created devices can be configured to operate for different periods of time.
Tests conducted on pigs demonstrated that this battery does not cause damage to the gastrointestinal tract. These results were reported in the scientific journal Nature Chemical Engineering.
