MIT's Tiny Ingestible Sensor Tracks Core Body Temperature from Within

MIT engineers have created a tiny ingestible sensor to track core body temperature. The device sends continuous updates from inside the gastrointestinal tract. This could improve early detection of infections and fevers. Standard methods for measuring temperature, such as oral or forehead readings, often fail to reflect true core body temperature. The new sensor aims to solve this by working from within the body.

The device is shaped like a small blueberry, measuring just 6 mm in diameter and 4 mm in height. Its compact size makes it easier to swallow than other ingestible sensors currently available. By monitoring temperature changes in the GI tract, it can help identify early signs of illness. The sensor offers a more accurate way to detect fever and infection. It may be especially useful for vulnerable groups who need close health monitoring. The technology could provide timely alerts before symptoms worsen.
