MEMS and Energy Harvesting Lab's research
1. MEMS actuators /sensors
Research in this area is focused on designing energy efficient electrostatic actuators/sensors to achieve high resolution and sensitivity. One unique property of MEMS devices is their nonlinear characteristic that can be exploited to improve their performance. In our lab, we study interesting nonlinear dynamical phenomenon such as softening, hardening, internal resonance, chaos, and parametric resonance to improve actuation ranges and sensitivity in MEMS devices. With advanced mathematical modeling and solution approaches, we are able to predict highly complex responses and alter their structures to satisfy certain requirements.
2. Energy Harvesting
Energy harvesting in the lab involves converting mechanical kinetic energy to electricity. Electricity is generated through piezoelectric, and triboelectric effects. Such energy harvesters find applications in structural health monitoring systems and biomedical sensors. The power generations are small in the range of milli- and micro-watts, though it is useful for emerging low power sensors. Ongoing projects include an implantable self-powered load sensor for a knee implant.
