A fluid dynamic polymer-based contact sensor (100) measures ambient pressure (103) based on the resistivity changes across the sensor under different ambient pressures.
The sensor may comprise a thoracic fluidsensor, a heart sounds sensor, a cardiac chamber or arterial pressure sensor, a respiration sensor, or a blood chemistry sensor, for example.
传感器例如可以包括胸液传感器、心音传感器、心腔压或动脉压传感器、呼吸传感器或血液化学传感器。
