Abstract

Based on the previously experimental study of the 900-MHz and 2.45-GHz Radio-frequency identification (RFID) chip design with standard CMOS processes, the objective of this project is to integrate the experience on the design and fabrication of wireless biomedical sensor chip, such as temperature, optical intensity and position sensors, as well as orthogonal polarization-based optical sensors. The polarization-based sensor chip provides the measurement information of investigated object-components. Indeed, this chip also shows the contribution on the biomedical sensor technology and the promotion on the application area such as the investigation of material properties. In the first year, we propose a new dual-band polarization-based sensor to measure the variation of orthogonal angle due to the perturbation of measured objects. After developed the basic theory and simulation model, we design the layout and post-simulation of the polarization-based array sensors. Meanwhile, experimental apparatus will be set up with already equipments and desired testing parts to measure the fabricated dual-band polarization-based sensor chip. In the second year, some peripheral circuits, such as decoders, scanners, buffers, and sensor amplifiers, will be implemented and integrated to the dual-band polarization-based sensors. Orthogonally polarimetric measurement exhibits the offset of aligned polarizing light. Image sensor-array and dual-band polarization analyzing CMOS sensor that will be integrated on the micro-object system is proposed in the last year. This polarimetric image-sensor chip will be simulated and fabricated as well as measured to provide the improvement on the image quality factor. Finally, the dual-band polarization-based image sensor will be integrated into the developed wireless biomedical sensor chip to promote its performance.
