Researchers have designed a small voltaic cell that are sustained by the acidic fluids in the stomach and generate enough power to run sensors or drug delivery devices that can reside in the gastrointestinal tract for extended periods. This type of power could offer a safer and longer-lasting alternative to the traditional batteries now used to power such devices.
