Edible electronics

10-Apr-2013 - USA

Scientists in the US have designed an ingestible electronic device that is composed entirely of edible materials and produces its own electric current. The ingestible current source consists of flexible polymer electrodes and a sodium ion electrochemical cell. Having flexible polymer electrodes means they can be folded into an edible capsule while the sodium ion cell serves as an on-board energy supply.  Potential applications include drug delivery and tissue simulation.
