Abstract

A novel micromachined electrode is designed and fabricated for a BSN-based vital signs monitoring system. Both theoretical calculation and ANSYS simulation show that buckling problem will not occur for the proposed microneedles during insertion process. The BSN-based vital signs routine monitoring system, which comprises of wireless mote, analog amplifier circuit board and SpO₂ (Saturation of Arterial Oxygen) probe, is able to measure physiological signs in real time and with minimum disturbance on quality of life. The proposed device is easy to wear and convenient to use. Using a dock with ZigBee adapter, a PDA phone can communicate with the mote and then display the ECG/PPG waveforms as well as the important indices of vital signs, such as heart beat rate, SpO₂ value and systolic blood pressure.
