BIOMEDICAL APPLICATIONS OF A COMMERCIAL CAPACITANCE TRANSDUCER,

Abstract

A capacitive displacement transducer with a linear response and constant sensitivity for a frequency range of 0-1,000 Hz is described. Its application to measurement of chest wall motions was verified using static displacements from flat and curved surfaces and both metal and human tissue. The transducer has been used to obtain recordings of apex motion, heart sounds, brachial and radial pulses. (Author)
