Revolutionary Ingestible Capsule for Monitoring Breathing and Heart Rates

Researchers from MIT, Celero Systems, and West Virginia University have developed an innovative ingestible capsule that monitors vital signs from within the gastrointestinal tract, offering a groundbreaking approach to diagnosing sleep apnea and potentially detecting opioid overdoses.

Innovative Capsule for Vital Sign Monitoring

The capsule, approximately the size of a multivitamin, contains an accelerometer that tracks breathing and heart rates. It is designed not only to aid in diagnosing obstructive sleep apnea but also to identify respiratory changes caused by opioids or conditions like asthma and COPD.

Clinical Trials and Research Findings

In a recent study with 10 volunteers, the ingestible sensor accurately monitored vital signs and detected sleep apnea episodes with no reported adverse effects. The capsule safely passed through the digestive system, confirmed by radiographic imaging two weeks after ingestion.

The device transmits data wirelessly to external devices, making it a less invasive and more comfortable alternative compared to traditional overnight sleep lab monitoring.

Technological Features and Potential Applications

Equipped with two batteries and a wireless antenna, the capsule detects subtle movements from heartbeats and lung expansion via its accelerometer. Animal tests confirmed its ability to measure breathing and heart rates accurately, including detecting opioid-induced respiratory depression.

Future Directions and Industry Impact

The research team plans to incorporate overdose reversal agents like nalmefene into the capsule for automatic drug release upon detecting critical respiratory changes. They are also exploring ways to extend capsule retention time within the stomach for prolonged monitoring.

Celero Systems, co-founded by MIT researchers, continues to develop sensors targeting sleep apnea detection and opioid overdose risk monitoring, aiming to provide timely assistance for high-risk individuals.
