Researchers have developed a tiny paper-based battery that can be swallowed to power internal medical devices, then dissolves safely in the digestive tract after several months. The technology, tested in pigs, could replace the need for surgical removal of implanted batteries.
Swallowed battery that dissolves after months? Great. So it powers a device until it doesn’t, then turns into god knows what in your gut. Pigs aren’t people. Where’s the output spec, the failure rate, the toxicity screen, the human trial? Call me when a battery doesn’t need a sequel. Until then, it’s a paperweight with a deadline.
