Jelly-like material could replace metals as electrical interfaces for pacemakers, cochlear implants, and other electronic implants

Do an image search for "electronic implants," and youll draw up a wide assortment of devices, from traditional pacemakers and cochlear implants to more futuristic brain and retinal microchips aimed at augmenting vision, treating depression, and restoring mobility.

MIT engineers developed a metal-free, Jell-O-like material that is as soft and tough as biological tissue and can conduct electricity similarly to conventional metals. The new material, which is a type of high-performance conducting polymer hydrogel, may one day replace metals in the electrodes of medical devices.
