Lab and Real-world Validation of a System for Monitoring Ingestive Behavior

University of Rhode Island and The University of Texas at Austin

The central goal of this NIH-funded project (1R01DK134546) is to validate and test a wearable device assembly pairing two validated instruments that can provide these measurements with good accuracy and low participant burden. One is a wrist-worn bite counter, which detects the wrist-roll motion associated with placing food in the mouth, tracking bite number and bites per minute for each eating episode. The other is a discreet chewing sensor adhered to the skin over the condyle bone, to detect chewing frequency and duration, as well as oral processing.
