BPN848: Highly Integrated, Compact Wearable Ultrasound System for Chronic Biosensing

Project ID BPN848

Abstract Recent advances in low-power ultrasonics have enabled highly integrated, compact ultrasound systems. In addition, new ultrasonic biosensing modalities for chronic sensing native of tissue or communicating with implanted sensor nodes motivate the need for a wearable ultrasound system. Here, we integrate a low-power, high-voltage transducer driver (Tang, 2015), into a highly compact wearable device designed to unobtrusively provide continuous ultrasound monitoring of subject biometrics. We demonstrate its capability by interfacing with one type of ultrasonic backscatter dust mote, the Neural Dust mote (Seo, 2016).
