Wearable and Transparent Bioelectronics for Wireless Remote Sensing

Abstract

In this talk, we will discuss two telemetric sensing principles for the wireless monitoring of physiological parameters with potential advantages of improved accuracy and sensitivity. We propose self-powered wireless biosensors based on graphene radio-frequency (RF) components, which have advantages of transparent, flexible, and monolithically integrated on biocompatible soft substrate. All-graphene wireless sensors is envisioned to consist of optically transparent graphene antenna and biosensor, which receives the fundamental tone and retransmits the sensed signal at its second harmonic, thus allowing low-noise sensing in a severe interference/clutter background. Pressure is also an important part of our human body. In the current paradigm, implantable wireless pressure sensors relies on magnetically coupling for signal readout, where the hardware is bulky and inadequate for wearable use. We investigate parity-time (PT) telemetric sensing to address this challenge. Low-cost sensing wearable devices for real-time reporting of physical data is critical in personalized alerts and managed care services.
