Wearable Sensors for Aging SocietyKenneth Shinozuka, USA Scientific American Science in Action Award, 15-16
I invented a low-cost wearable sensor technology for real-time, reliable detection of patients’ wandering out of bed. The sensor signal caused by the patient’s body weight will wirelessly trigger an audible alert in a caregiver’s Smartphone. In this project, I developed an ultra-thin film sensor that is comfortable to wear under the foot, a coin-sized sensor circuit enabled by Bluetooth Low Energy, and an app that transforms a Smartphone into a caregiver’s monitor. Integrating these critical components, I made two prototypes and successfully demonstrated, through a six-month trial, their reliability and usefulness in protecting patients’ safety and alleviating caregivers’ stress.
