Ingested electronics could monitor gastrointestinal tract

04/11/2013 | ElectroIQ

Devices swallowed in pill form would employ biosensors to measure patients' biomarkers or monitor gastric problems. The devices, under development at Carnegie Mellon University, are made of "flexible polymer electrodes and a sodium ion electrochemical cell, which allows us to fold the mechanism into an edible pill that encapsulates the device," explained Christopher Bettinger, assistant professor in the school's departments of Materials Science and Engineering and Biomedical Engineering. They run on a battery activated from outside once the device is consumed and reaches the designated spot in the gastrointestinal tract.
