Swallowing this pill-shaped sensor could help you avoid invasive procedures

Ingestible robotics has been a fascinating and growing field for the last several years. We’ve already seen a handful of startups working to commercialize a technology that could allow for internal monitoring, medicine delivery and more, without the need for invasive procedure.
This new project from a joint team at Caltech and MIT highlights a slightly more basic approach to the category, cramming sensors into a pill-shaped ingestible module full of sensors. The system relies on electromagnetic fields, using a coil operated outside of the body to detect the mechanism’s progression through the
