Distinguished Lecture: Micro and Nanotechnology-Enabled Sensors, Antennas and Circuits for Internet-of-Things and Telemedicine

#STEM #sensor #council #sensors #bio-medical #technology #sensing

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 driven force for many new technologies, such as smart city, telemedicine, telediagnosis, and point-of-care test (POCT), to name a few. This seminar will give an overview of our recent progress on micro and nanotechnology-enabled sensors and integrated systems. The first part of this talk will discuss new types of compact, low-cost, and batteryless wireless biosensors based on chemically-reconfigurable frequency modulators and oscillators that are constituted by nanomaterial devices and circuits [1]. New stretchable, breathable, and biocompatible antennas, interconnects, and passive devices based on novel micro/nano-materials, as well as their applications in wearable electronics (i.e., smart skin) will also be discussed [2]-[3]. The second part of this talk will discuss how the concept of symmetries in quantum mechanics can be implemented using electronic circuitries and applied to telemetric sensing systems for enhancing sensitivity and resolvability of wireless micro/nano-sensors, with some in-vivo demonstrations [4]-[5]. The final part of this talk will showcase new 2D material-based RF/analog circuits that exploit the device’s entropy to generate physical unclonable function (PUF)-based encryption keys for identification, authorization, and securing wireless sensors, RFID tags and IoT devices [6]-[7].
