In this study, we report a signal processing method for an immune-sensor chip, which uses immune-assay to trap a target material on it. The trapped material is labeled with micro magnetic beads and detected by Hall sensor array fabricated in a CMOS chip. To improve the signal-to-noise ratio of the Hall sensor, output signal is modulated at a high frequency region. The signal processing circuit, which...
This paper reports an on-chip micro battery and a micro electrochromic display, both are key components of a disposable wireless bio-sensor. The on-chip micro battery had a simple structure and it could generate open circuit voltage and power density as high as 1.6 V and 78 µW/mm2, respectively. The micro electrochromic display made of micro patterned polyaniline could be made on an imitation of CMOS...
