Aimed at the defects of single pulse pressure sensor

a technology of touch membrane button panel is presented.A sensor with several routeway pulse pressure sensors is made to obtain several routeway pulse signals and the associated hardware circuitry is designed to conduct the pulse signal.Experimental results show that the linearity and repeatability of the pulse pressure sensor are excellent

and the sensitivity is up to 1 100 μv/mmHg in pressure of 0

3

00 mmHg.The pulse signals acquired by pulse sensor are displayed on the computer monitor through the oscilloscope serial communication expansion module.The effect is remarkable.
