The EECS Research Summary for 2003


Corona MEMS for Wide Study Area Air Particulate Monitoring

Beelee Chua1 and Zhihong Li2
(Professor Norman Tien)
BSAC

The goal of this project is a low cost device that is able to size and count air particulates with sizes under PM 2.5 and retain the particulates for subsequent composition analysis. Multitudes of such devices can be deployed over a wide study area (such as downtown Sacramento) to monitor the air quality in situ and generate air particulate spatial and temporal maps. We will explore integration with pollutant sensors such as that for NOx and SO2. We aim to extend the applications of a micro corona discharge device to a micro ozone generator for biological sterilizing units, non-mechanical micro air pumps, and ESD control.

RF Dielectric Fluid Immersed Silicon MEMS Tunable Capacitors

Daniel T. McCormick1 and Dr. Zhihong Li2
(Professor Norman Tien)
BSAC

The objective of this project is to develop micro-electromechanical tunable capacitors employing dielectric fluids. In the case of electrostatic, mechanically tunable capacitors, the goal is to increase the capacitance per unit area and the tuning range, reduce the mechanical noise, and improve long-term reliability.

Minimally Invasive MEMS-based Optical Coherence Tomography for In-Vivo Imaging

Daniel T. McCormick1
(Professor Norman Tien)
BSAC

The objective of this work is to develop a miniature MEMS-based probe for high speed, high resolution, in-vivo optical coherence tomography (OCT) imaging. The realization of a small scale OCT system with high spatial and velocity resolution as well as rapid image acquisition rates has numerous potential applications in medicine, including real-time optical biopsies.

Biomimetic Directional Microphone Diaphragm

Kyutae Yoo1
(Professor Norman Tien)
BSAC

A novel micromachined biomimetic device: the directional diaphragm for acoustic transducers, has been designed, modeled, simulated, fabricated, and tested. We have fabricated a directional microphone by employing the biomimetic directional diaphragm.
