The prototype is tested with the preset static pressure between −60 mmHg and 300 mmHg. For
the dynamic pressure, the frequency is set to be 1 Hz, and the systolic and diastolic pressure is set
to be 120 mmHg and 60 mmHg respectively. A pressure transducer TS110 and a Tektronix oscil-
loscope DPO5054B are used to monitor the simulation results, and evaluate the repeatability and
measurement accuracy. The tranducer has a measurement range of −600 mmHg ∼ +600 mmHg,
with the detection accuracy of 0.15% and the output voltage up to 5 V.
The generated static pressure is adjusted to 300 mmHg, 240 mmHg, 150 mmHg, 60 mmHg,
30 mmHg, ...
