Scientists create edible and rechargeable battery

How edible batteries might be used

The hope is for this type of battery to be used to power medical devices that need to travel through your digestive system. Currently, tools like wireless capsule endoscopy cameras can capture images of your digestive tract, but none of them are powered by an energy source quite like this.


Until the edible battery becomes more widely adopted, the leading battery manufacturers are using preventative measures such as bitter coating to discourage children from swallowing button batteries. No word on whether or not the beeswax one is exactly delicious, but even if it’s bland, it’s probably nothing a little hot sauce can’t fix.
