Researchers say ingestible sensor could help with diagnosing GI disorders

Engineers at MIT and Caltech have developed an ingestible sensor that could more easily diagnose gastrointestinal motility disorders.

This advance could help with the diagnosis of constipation, gastroesophageal reflux disease and gastroparesis.

The engineers designed their tiny sensor to detect a magnetic field produced by an electromagnetic coil located outside of the patient’s body. The strength of the field varies with distance from the coil, which allows for the calculation of the sensor’s position based on its measurement of the magnetic field.

In a new study, the researchers demonstrated the ability to track the sensor as it moved through the digestive tract of large animals. They believe this could offer an alternat…
