Bio-Sensing and Monitor System Design by Integrating Replaceable Micro Array Probes and Amplifier with an Wireless Active RFID Tag

This research provides a bio-sensing and monitor system, which integrates replaceable flexible non-fragile bio-probe, Thin-Film-Transistor (TFT) amplifier, as well as an active RFID tag, such that the new wireless device can improve the signal-to-noise (S/N) ratio and impedance matching problems. Besides, the bio-probe device can be disposed to conform to the profile of a bio-body and to improve the electrical contact property. The detailed device fabrication and testing processes are given, the result of probe resistance is 2.7 KΩ, and the monitoring range of the wireless RFID system is 15m, which is very useful for remote monitoring.
