ABSTRACT:
A biophysical sensor including a sound vibration sensing element (12) to produce a sensed output, and two or more separate signal processing paths to process the sensed outputs to produce output signals. The output signals may reflect specific frequency bands within the raw biological signal. In a further aspect the invention concerns an electronic stethoscope in which the sound vibration sensing element (12) is a PVDF membrane, the signal processing involves an operational amplifier (OP amp) (10) connected to the PVDF membrane, and a unity gain buffer amplifier is connected to the output of the OP amp to allow the connection of headphones directly to the sensor output.
