Abstract
A multi-purpose sensor a single unit is capable of measuring both electric signals from the object and pressures at the same time and which yet is compact, lightweight and cheap enough to be used as a disposable product. Element in a disk form that is composed of carbon fibers superposed in layers at low density to produce a felt-like texture is surrounded with concentric cylindrical holder. Terminal is connected to an end face of each of element and holder whereas terminal is connected to the other end face, whereby the deformation of element due to an externally applied force is picked up as a voltage change.
