Integrated microsystems that leverage the benefits of microfabricated sensors and actuators,  integrated circuit (IC) technology, and advanced packaging techniques are important for a variety of applications. In this talk, I will present three microsystems for advanced sensing applications.  First, I will present a standalone wireless and battery-less microsystem for high-performance strain-sensing applications in which stringent performance requirements are demanded to enable the early detection of catastrophic mechanical system failure. Next, I will present a biomechanical sensing microsystem consisting of a microfabricated, capacitive, ground-reaction sensor array and interface IC mounted in the heel of a boot for the detection of zero-velocity during stride.  This information is crucial to enhance the accuracy of inertial measurement units for personal navigation in GPS-denied environments. The third microsystem I will present is a miniaturized, autonomous, integrated measurement platform for complex dielectric permittivity measurement versus frequency (i.e., dielectric spectroscopy) in a broad frequency range from MHz to GHz. One application for this microsystem is directed at proteomics for high-throughput studies of protein structure and function to pursue scientific research or low-cost diagnostics with a portable platform. For each of these microsystems, I will describe how analog/mixed-signal/RF integrated circuit design is coupled with microfabricated sensors and advanced packaging techniques to achieve the performance requirements of the advanced sensing application.


Michael A. Suster received his Ph.D. degree in electrical engineering from CWRU in 2011. After completing his Ph.D., he held the position of Postdoctoral Researcher in the Electrical and Computer Engineering Department at the University of Utah and is currently a Research Associate in the EECS Department at CWRU. His research interests include analog/mixed-signal/RF integrated circuits for micro/nano-sensors and CMOS biosensors. His work has been published in over 25 top academic journals and international conferences, including the IEEE International Solid-State Circuits Conference (ISSCC), IEEE Custom Integrated Circuits Conference (CICC), and IEEE Journal of Solid-State Circuits (JSSC).
