Micro and Nanotechnology-Driven Wireless Bioelectronics

Micro and Nanotechnology-Driven Wireless Bioelectronics

Presenter: Pai-Yen Chen, University of Illinois Chicago

Abstract: With the rapid advent in sensors and actuators, and the ever-advancing wireless technologies, the idea of internet-of-things (IoTs) has had a revolutionary impact on ubiquitous computing with massive amount of data from the “5G/B5G-connected” smart objects. This new paradigm has become the driving force for many new technologies, such as smart cities, telemedicine, telediagnosis, and point-of-care testing (POCT). This talk will give an overview of recent progress on micro/nanotechnology-driven wireless sensors and integrated systems. The first part of this talk will discuss noise-immune, batteryless and wireless harmonic/intermodulation sensors for physical and (bio-)chemical sensing, as well as new types of compact, passive harmonic biosensors based on chemically-reconfigurable frequency modulators built using nanomaterial-based RF circuits. In addition, wearable antennas and circuitries based on lightweight, stretchable nanocomposite materials will be discussed, along with their applications in wearable electronics and smart skins. The second part of this talk include discussions on how the concepts of “symmetries” and “time crystals” in quantum mechanics can be implemented using RF circuits and applied to enhance sensitivity and resolvability of wireless micro/nano-sensors, with some in-vivo demonstrations. The final part of this talk will showcase nanomaterial-based RF/analog circuits that leverage the intrinsically high entropy to generate electromagnetically unclonable function (EMUF)-based cryptographic keys for identifying and securing resource-scarce wireless sensors, RFID tags, and IoT devices.
