Research Project

• Automotive Clutch System: Designed and built an automotive clutch system based on an embedded microcontroller (Freescale 68HC12). The microcontroller was programmed to provide a signal to engage or disengage an electromagnetic clutch. The real-time interrupt function was used to measure the rotation speed of the flywheel and engine. The hardware interface was built to display the flywheel and engine speeds.

• 3D Localization System: Designed of a passive wireless SAW correlator for three-dimensional localization sensing applications. This project was funded by ADMOTECH Inc. The correlator was designed to receive and respond a 31-bit Barker Code sequence in 915 MHz range. The interrogation system provided by ADMOTECH Inc was used to test the performance of SAW sensors.

• Biosensor: Developed high sensitive biosensors based on Acoustic Wave Technology. The sensors were designed and analyzed using FEA method in both CoventorWare and COMSOL platforms. The sensing characteristic of the sensor was investigated by measuring various concentrations of antibody. The tools such as network analyzer and LCR meter were used in this project to characterize the performance of sensors.

• Chemical Sensor: Developed a Surface Acoustic Wave (SAW) sensor for detecting the hydrogen gas. A one-dimensional numerical model was built to predict the performance of the sensor. The sensing characteristic of the fabricated sensor was investigated by detecting various concentration of hydrogen gas. The tools such as network analyzer and LCR meter were used to characterize the performance of sensors.

Course Project

• Ultrasonic Sensing System: Developed an ultrasonic sensing system using a microcontroller. A LCD displayer was used to display the distance which was measured by ultrasonic device. The C and assembly languages were used in this project to design, implement and debug the firmware. The hardware interfaces such as LCD display module and driving circuit was tested and debugged using a digital analyzer, oscilloscope and multimeter.

• Microprocessor Design: Developed a VME_Bus and SDRAM memory block along with it controller. The project was based upon VHDL programming and Field Programmable Gate Arrays (FPGAs). The software Xilinx ISE platform was used to in this project.

• MEMS sensors: Designed, fabricated and tested a two-dimensional gyroscope/accelerometer and EDNMOS readout circuitries. The sensors and readout circuitries were designed using CoventorWare and MentorGraphs, respectively. The performance of sensors and readout circuitries were investigated through a LCR meter, an oscilloscope, a source meter and a network analyzer.
