SENSOR, SENSOR PAD AND SENSOR ARRAY FOR DETECTING INFRASONIC ACOUSTIC SIGNALS

摘要

A sensor, sensor pad and sensor array for detecting infrasonic signals in a living organism is provided. The sensor, sensor pad and/or array can be utilized for detecting, determining and/or diagnosing level of stenosis, occlusion, or aneurysm in arteries, or other similar diagnosis. The sensor can include unique circuitry in the form of a piezoelectric plate or element sandwiched between two conductive O-rings.
