Battery-free sensor brace unveils crucial health data via smartphone

Densor, a battery-free sensor platform that can be worn in the mouth via a standard dental brace or a “bite splint

The human mouth holds a wealth of information about overall health. From body temperature to head and jaw movements during sleep, this data can be essential for understanding health conditions and dental issues. However, collecting such data is often cumbersome and uncomfortable. Researchers from TU Delft, in collaboration with Radboudumc, have developed a groundbreaking new technology: Densor, a battery-free sensor platform that can be worn in the mouth via a standard dental brace or a “bite splint.” This innovative open-source technology enables safe and user-friendly long-term oral measurements. Uniquely, it requires no additional hardware—just a smartphone for charging and data reading. The user study was published in Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies.
