Edible batteries inspired by rice paper power medical devices in the body

So, I just read about this fascinating breakthrough where researchers have created batteries made from edible materials like rice paper. It is honestly brilliant because these tiny power sources can safely dissolve inside the body after powering ingestible medical devices. They tested this in pigs, using the battery to run an RFID tag and even stimulate hunger hormones, which is just incredible. And here is the thing - by using micronutrients like magnesium, they avoid all the toxic risks of conventional batteries. Which brings me to the future of medicine, where we might soon have non-invasive, swallowable tech to treat all sorts of conditions.
