Micromachined Resonators: The Next Wave in Sensing

Abstract

Microelectromechanical resonators are rapidly emerging into a major class of devices that span applications space from clocking, sensing, and smart switching devices. Micromachined resonators are available in many forms from acoustic wave resonators, electromechanical and flexure resonators, and optical resonators and can span frequency ranges from few hundred kilohertz into terahertz. Crystal resonators have dominated the clocking and timing market, and in 2106 generated over 86% of the total resonators revenue. However, by 2021 MEMS resonators are forecast to increase their market penetration and sales to over 45% of the market. Smartphones manufacturers are the key adopted of crystal resonators, whereas MEMS resonators find utility in integrated circuit (IC) timing systems. According to Technavio, the global crystal resonator market is expected to reach 1.1375 billion by 2021. With growing demand for MEMS resonators, the market for resonators is expected to grow at 17.19% CAGR. Resonators are also at the heart of micromachined gyroscopes, increasing number of chemical and biosensors, and most recently in the demonstration zero-power smart sensors. In addition to examining the role of resonator in various sensing applications, this talk will also examine the approach towards designing next generation biomedical and point of care sensors based upon ideas of crowd sensing. This approach is capable of improving the time to market for such devices which have typically taken upwards of a decade making the commercialization of such devices by start-ups and small businesses a real challenge.

Bio

Srinivas Tadigadapa is a Professor and Chair of the Department of Electrical and Computer Engineering at Northeastern University in Boston, USA. From 2000 – 2017 he was a Professor of Electrical Engineering at the Pennsylvania State University. Prior to that, he was the Vice President of Manufacturing at Integrated Sensing Systems Inc., and was involved with the design, fabrication, packaging, reliability, and manufacturing of micromachined silicon pressure and Coriolis flow sensors. Dr. Tadigadapa’s primary research interest is in the interdisciplinary field of microelectromechanical systems (MEMS) and in the design, optimization, fabrication, and testing of MEMS transducers. Specifically his research focus is on fabrication of novel micro and nano-sensors and actuators by integrating non-traditional materials using silicon microfabrication techniques and exploring phenomenon at the micro-nano interfaces. He has published over 180 peer reviewed papers in the field of MEMS and is the inventor on ten patents. He has been a research fellow at the University of Karlsruhe, Germany and a Visiting Professor at Otto von Guericke University, Magdeburg, Germany, and University College, Cork, Ireland. He was awarded the Alexander von Humboldt fellowship in Germany and the Walton fellowship by the Science Foundation of Ireland. He is a Fellow of the IEEE, The Institute of Physics, London, and a Life-Fellow of the Cambridge Philosophical Society. He was the Chair of the Technical Program Committee for IEEE SENSORS 2015 – 2017 conferences and the founding editor of IEEE Sensors Letters.
