MEMS Energy Systems Sensing: We are researching low-cost microfabricated energy sensors. Our goal is to develop sensing modules that can be ubiquitously distributed throughout the grid to measure operational and diagnostic parameters. The use of MEMS fabrication technologies and wafer-level integration allows us to dramatically reduce the cost of such sensors, enabling their ubiquitous deployment. Proximity-based sensing enables non-contact monitoring of electric circuits.

Energy Harvesting: Energy harvesting is the science of extracting useful energy from the ambient environment. Our piezoelectric AC energy scavengers are designed to provide power for energy sensing modules via an electromagnetic coupling to the current-carrying conductor enhanced by electromechanical resonance at power frequencies.

Air Microfluidics - MEMS Particulate Matter (PM) Sensor: Airborne particulate matter (PM) are small solid particles or liquid droplets that are suspended in the atmosphere, such as for example diesel exhaust, tobacco smoke, volcanic ash, or pollen. Specifically, so called fine particles, i.e., particles measuring 2.5 µm in diameter or smaller (PM_2.5) are particularly harmful as they penetrate deep into our respiratory system. We are working on a MEMS-based PM sensor using air microfluidics. The air-microfluidic circuit separates, condenses and deposits the particulates onto a mass-sensitive MEMS resonator (FBAR). Such a microfluidic circuit will enable sophisticated detection and speciation of airborne PM.

Microrobotics: Microrobotic systems enable us to interact with microscale environments, presenting tremendous opportunities in medicine, manufacturing, information security and other areas. My research encompasses micro-mechatronic designs, fabrication techniques, and control theories for groups of microrobots. As part of my Ph.D. work we developed world’s smallest mobile robot, first multi-micrororbotic system, and implemented microassembly using our microrobots. I am also interested in distributed MEMS sensors, biomimetic microsystems and nanorobotics.
Upcoming workshop: The Different Sizes of Small-Scale Robotics: from Nano-, to Millimeter-Sized Robotic Systems and Applications. In conjunction with 2013 IEEE International Conference on Robotics and Automation (ICRA 2013), Karlsruhe, Germany, May 6 - 10, 2013.
