Abstract
We have designed and fabricated the first single-wafer proportional micro control valve with built-in capacitive dis-placement sensing. The displacement sensor can facilitate high-speed active proportional control of gas flow through the valve. This is an essential requirement for non-invasive blood pressure waveform monitoring based on following the arte-rial pressure with a counter pressure. We demonstrate a near-linear relation between valve plate displacement and inverse capacitance. The valve shows monotonously increasing flow with decreasing capacitance and increasing pressure.
