Abstract
An instrument for viscoelastic measurement, particularly for breast palpation, uses a plurality of spaced elongated electret strips which are pressed into the body being examined by a pressure member which applies a given periodic or steady stress to the tissue beneath the electret strips. Electronic measuring means then interrogates the output voltage of each of the strips in turn and the output of each strip is displayed to produce a display characteristic which will show the presence of an inclusion in the breast tissue being examined.
