Sensing device for acoustic energy
First Claim
1. A sensing device for capturing cardiac output and acoutstic output, said sensing device comprising:
- a pliable diaphragm formed from a piezoelectric transducer material for generating voltage signals in response to excitation by acoustic vibratory outputs;
metallization layers on opposed surfaces of said diaphragm for receiving and transmitting said excitation signals generated by said diaphragm; and
a layer of adhesive material attached to and in direct contact with one of said metallization layers for mechanically coupling the sensing device to a subject'"'"'s flesh in a way that said sensing device and said flesh conform and become one so as to insure a maximum amount of said acoustic and vibratory outputs being received by said diaphragm.

Abstract
A sensing device for capturing acoustic heart sounds has a diaphragm formed from a piezoelectric transducer material which generates excitation signals in response to acoustic and vibratory energy outputs. The sensing device includes metallization layers on the diaphragm for receiving and transmitting the excitation signals to an output display device via associated electrical contacts and electrical leads and also includes a layer of adhesive material for coupling the sensing device to the subject. The sensing device further includes snap connectors for allowing the device to be quickly disengaged from electrical leads and discarded. A patch sensor device is disclosed which enables acoustic outputs to be triangulated and pinpointed.
