Pai-Yen Chen of University of Illinois Chicago (UIC)

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 our recent progress on micro/nanotechnology-driven wireless sensors and integrated systems. 
The first part of this talk will discuss low-noise, batteryless and wireless harmonic/intermodulation sensors for physical and (bio-)chemical sensing, as well as ultracompact harmonic biosensors based on chemically-reconfigurable frequency modulators built using nanomaterial-based RF circuits. In addition, wearable antennas based on lightweight and stretchable nanocomposite materials will be discussed, along with their applications in wearable electronics and smart skins. The second part of this talk will discuss how the concepts of “PT-symmetry” originating from quantum mechanics and “time crystal” can be implemented using RF circuits and applied to enhance sensitivity and  resolvability of wireless micro/nanosensors, 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 IoTs.
