IEEE SENSORS DISTINGUISHED LECTURE: Radio Telemetry of Wireless Micro/Nano-Sensors

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-connected” smart objects. This new paradigm has become the driving force for many new technologies, such as smart health, telemedicine, telediagnosis, and point-of-care testing. This talk will provide an overview of recent advances in telemetry techniques, micro/nanotechnology-driven wireless sensors and integrated systems. The first part of this talk will discuss new types of long-range (far-field), batteryless and wireless sensors for physical and (bio-)chemical sensing in noisy environments, as well as compact, passive wireless biosensors based on chemically-reconfigurable oscillators and modulators built using nanomaterial-based transistors. Additionally, wearable antennas and circuits based on lightweight, flexible and stretchable nanocomposite materials will be discussed, along with their applications in smart skins. The second part of this talk will discuss how the concepts of “PT-symmetry” and “time crystals” originated in quantum physics can be implemented using electronic circuits and applied to enhance the sensitivity and resolvability of near-field sensor telemetry, with demonstrations on wearable and implantable wireless micro/nano-sensors.
