MEMS resonators have attracted the attention of the scientific community for multiple decades due to their attractive features. Today, MEMS resonator-based devices are being utilized in a wide range of applications ranging from airplanes, microphones, indoor air quality sensors, cell phones, and digital logic applications. With the increasing demand to reduce the power consumption and increase functionality at the device level, self-powered sensors have emerged. Self-powered sensors are commonly composed of sensing elements connected to a logic processing unit and powered by an energy harvester. These sensors, which are battery-free and can be operated independently, are important in a wide range of applications including biomedical and the oil and gas industry.

MEMS based resonators are based on the vibration of complaint movable structure that are inherently nonlinear. In this talk, we demonstrate that by developing a proper understanding of the nonlinear dynamics of these structures, a new class of smart self-powered sensors could be realized. The talk will overview the possibility of realizing a smart gas sensor that can be autonomously triggered if the gas concentration exceeds a certain threshold. We will discuss the potential of realizing multiple logic gates using a single mems resonator. The talk will end on future directions and perspectives.



Nizar Jaber, (IEEE Member) received the B.Sc. degree from the Jordan University of Sciences and Technology, Jordan, in 2010, and the master’s and Ph.D. degrees in mechanical engineering from the King Abdullah University of Science and Technology (KAUST) in 2014 and 2018, respectively. In 2019, he joined the School of Mechanical Engineering, Purdue University, West Lafayette, IN, USA, as a Post-Doctoral Fellow. He is currently working as an Assistant Professor with the Department of Mechanical Engineering and the Center for Communication Systems and Sensing, King Fahd University of Petroleum and Minerals, Dhahran, Saudi Arabia. His research interests include linear and nonlinear dynamics of MEMS-based resonators with their applications in MEMS sensors and actuators.
