MIT's Tiny Ingestible Sensor Tracks Core Body Temperature Safely

MIT engineers have created a tiny ingestible sensor to monitor core body temperature. The device provides continuous updates from inside the gastrointestinal tract. It is shaped like a small blueberry, measuring just 6 mm across and 4 mm high. Current methods for measuring temperature, such as oral or forehead readings, often fail to reflect true core body temperature. Existing ingestible sensors are bulkier and can block the digestive tract, posing risks to users.

The new sensor offers a safer and more accurate alternative. It can detect early signs of infections, which is particularly useful for vulnerable groups. These include patients undergoing chemotherapy or those on immunosuppressive medications. The sensor’s ability to track core temperature could improve the detection of fevers and illnesses. It may provide a reliable way to assess health risks in at-risk individuals. The compact design reduces the chance of obstructions in the digestive system.
