Michel M. Maharbiz

Former BSAC Co-Director
Electrical Engineering and Computer Sciences
Berkeley Sensor & Actuator Center (BSAC)
Ph.D. 2003

Michel M. Maharbiz is a professor in the Department of Electrical Engineering and Computer Science at the University of California, Berkeley and a Co-Director of the Berkeley Sensor & Actuator Center.

Professor Maharbiz's research focuses on the extreme miniaturization of technology focused on building synthetic interfaces to cells and organisms. He is one of the inventors of "neural dust", an ultrasonic interface for vanishingly small implants in the body. His group is also known for developing the world’s first remotely radio-controlled...

1994
This thesis describes a general system simulation of microelectromechanical systems (MEMS) based on lumped-parameter modeling. First-order analytic models are derived for mechanical equations of motion of a suspended plate, squeeze-film damping,...

A surface micromachined, capacitive accelerometer is described which integrates the mechanical sensing microstructures with CMOS detection circuits. The capacitive sensing structure consists of two polysilicon layers with the sensing and feedback electrodes...

Electrostatic Comb Drive for Resonant Sensor and Actuator Applications

William C.-K. Tang
Roger T. Howe
1990

Interdigitated finger (comb) structures are demonstarted to be effective for electrostatically exciting the resonance of polycrystalline-silicon (polysilicon) microstrucutres parallel to the plane of the substrate. Linear plates suspended by a pair of folded-cantilever truss as well as torsional plates suspended by spiral and serpentine springs are fabricated from a 2 um-thick phosphorus-doped low-pressure chemical-vapor deposited (LPCVD) polysilicon film. Three experimental methods are used to characterize quasi-static and resonant motions: microscopic illumination, observation with a...
