University of Illinois Urbana-Champaign, Tufts University, and Northwestern University researchers are developing dissolvable, implantable electronics. “Transient electronics,” as the team calls the new technology, are biocompatible, biodegradable devices that can provide therapeutic functions in the body for a programmed amount of time and then safely and completely dissolve. Circuits in the devices are made of thin biocompatible metals that can dissolve in days or weeks. Layers of silk cover the circuits and determine how quickly the implant will dissolve. Thicker layers will take longer to dissolve and in this way scientists can control the longevity of an implanted device.
