EnteroPhone™

A wireless, ingestible device monitors heart and breathing rates by listening to the body's sounds and senses core temperature, all from within the gastrointestinal tract.
The Laboratory's advanced work in miniaturized electronics enabled the development of EnteroPhone™.

EnteroPhone™ is an ingestible electronic capsule about the size of a multivitamin, yet it contains an array of advanced sensors that can monitor a person's vital signs from inside the body. EnteroPhone™ listens to heart and lung sounds, and it measures body core temperature, movement, and gastrointestinal pressure. A custom piezoelectric hydrophone assembly, thermistor, accelerometer, and barometer are built into EnteroPhone™ to capture these biosignals. These data are processed on board the capsule within the gastrointestinal tract, then transmitted wirelessly to an external processor that delivers reliable, useful information about a person's physiological status. EnteroPhone™ could give physicians, physical therapists, and athletic trainers a tool that monitors a person's vital signs without using uncomfortable external sensors or surgically implanted devices. A team from Lincoln Laboratory and MIT campus developed and tested this technology.
