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.
Claims7
A multi-purpose sensor for detecting more than one kind of vital sign from a subject, when the sensor is attached to the skin surface of the subject, the multi-purpose sensor comprising:
- an element formed of conductive fibers in a shape of a plate having a top face and a bottom face, said bottom face being closer than said top face to the skin surface of the subject;
- a flat holder having a top face and a bottom face and a center hole, said flat holder disposed around an outer perimeter of said element, an adhesive layer being provided on said bottom face of said holder, said holder being no more than generally the same in thickness as said element;
- and
- a pair of terminals respectively connected electrically to both said top and said bottom faces of said element and held on both said top and said bottom faces of said holder, a first of said terminals being connected to said top faces and a second of said terminals being connected to said bottom faces.
