Batteries that break down in the body could power ingestible medical devices
MIT researchers have developed a biodegradable, ingestible battery made from food-safe materials like magnesium and cellulose. This innovation aims to provide a safe power source for temporary internal medical devices, eliminating the need for toxic components or surgical retrieval.
Why it matters
It represents a breakthrough in medical technology, enabling less invasive diagnostic and therapeutic procedures within the gastrointestinal tract.
The edible battery is small enough to power devices that can be swallowed with a glass of water. Once the device’s function is complete the battery can safely degrade in the body, along with the rest of the device
A new type of edible battery can operate inside the body for a limited period before being fully broken down in the gut, offering a way to power temporary internal medical devices.
