Ingestible electronics for diagnostics and therapy

The gastrointestinal (GI) tract offers the opportunity to detect physiological and pathophysiological signals from the human body. Ingestible electronics can gain close proximity to major organs through the GI tract and therefore can serve as clinical tools for diagnostics and therapy. In this Review, we summarize the physiological and anatomical characteristics of the GI tract, which present both challenges and opportunities for the development...
