Carnegie Mellon University researchers are developing edible electronic devices that can be implanted in the body to improve patient care.

Bettinger, along with Jay Whitacre, a professor of materials science and engineering, is creating edible power sources for medical devices that can be taken orally using materials found in the daily diet.

"Our design involves flexible polymer electrodes and a sodium ion electrochemical cell, which allows us to fold the mechanism into an edible pill that encapsulates the device," Bettinger said.Bettinger reports that the battery could power biosensors to measure biomarkers or monitor gastric problems. The battery also could be used to stimulate damaged tissue or help in targeted drug delivery for certain types of cancer.
