Biodegradable batteries to power smart medical devices

Batteries made from pigments found in cuttlefish ink may lead to edible, dissolvable power sources for new kinds of medical devices. Researchers led by Carnegie Mellon University materials scientist Christopher Bettinger demonstrated the new battery. “Instead of lithium and toxic electrolytes that work really well but aren’t biocompatible, we chose simple materials of biological origin,” Bettinger says.
