摘要：The present invention relates to an acoustic sensor device for capturing internalbody sounds. The acoustic sensor device is designed to sense the flexing of a patient'sskin that is a result of the localized nature of internal body sounds, especially thepatient's heart sounds, and generate an electrical signal analogous to the flexure of theskin. The acoustic sensing device of the present invention has as its principal componentstwo thin film piezoelectric sensing portions, preferably formed from polyvinylidenefluoride or a similar piezoelectric material, two layers of a compliant, substantiallyincompressible material, a flexible and elastic adhesive layer between respective ones ofthe sensing portions and the incompressible material layers, an electrical connector atone end of the sensing device, an optional neutral plane inducer, an electrostatic shieldfor the electrical connector, a moisture barrier/protective coating, and an optionaladhesive or cream layer for adhering the sensor device to the skin of the patient.
