Persistent Sensing using ultra-low-power sub-cubic-millimeter devices for Biosensor Interfaces and Heterogeneous Networks
Abstract
Ubiquitous sensor arrays in ecosystems surrounding us have created an interesting conundrum, i.e. the design of these ecosystems and for that matter even electronic circuits for the worst-case variations have resulted in huge cost overruns and inefficiencies with economy-of-scale. This talk will focus on two systems currently being researched at Systems-On-Chip (SoC) Lab at Washington State University that enables efficient integration and implementation of multi-sensor arrays. The first system will describe a multi-channel sensor array for human vital signs monitoring. A mixture of disruptive technologies from signal processing and information theory, circuit design, nanofibers and additive printing are discussed towards achieving a unified goal of a flexible and reconfigurable vital signs sensor for different biometrics. Applications of sub-Nyquist sampling techniques and additively printed touch sensors for measurement of human electrocardiogram will be demonstrated. The second system will describe a combination of piezo-sensor and radio-frequency phenomenon to capture facial muscular movements in preemies. We will conclude the talk with future directions and open research challenges towards an efficient energy-harvested printed sensor array with integrated RF communications.
Biography
Subhanshu Gupta is a faculty in School of Electrical Engineering and Computer Sciences at Washington State University, Pullman. He received his Ph.D. from the University of Washington, Seattle, WA, USA in 2011 He was with the RFIC/Mixed Signal group at Maxlinear from 2011-14 where he worked on silicon driven circuits and systems for broadband transceivers used in cable/satellite/infrastructure communication applications. From 2015, he has been an Assistant Professor of Electrical Engineering at Washington State University where he is supervising over Systems-on-Chip Lab. His current research interests include energy-efficient integrated circuits (IC) and systems for millimeter-wave communication and persistent sensing using information-aware signal processing for long-term monitoring.
