ABSTRACT:
The present invention relates to an acoustic sensor having utility in biomedical applications. The sensor is applied to the skin of a patient and is capable of measuring the flexure of the skin caused by acoustic sounds beneath the skin and converting the skin flexure into electrical signals representative of the acoustic sounds. The sensor is formed from a single piece of piezoelectric material having electrically conductive areas on two spaced apart and opposed surfaces. The electrically conductive areas are electrically connected to electrical contacts or connector pins which may be used to hook up the sensor to a measuring device. A method for forming the sensor is also described.
