Abstract:
A combination thermal and vibration sensor, comprising:(a) a plastic film exhibiting pyroelectric and piezoelectric properties with first and second major surfaces and having a predetermined shape configuration, said predetermined shape configuration including a generally rectangular central segment with first and second obliquely projecting arms at adjacent corners thereof and an elongated tab disposed between said obliquely projecting arms; (b) a thin layer of conductive material deposited upon and substantially covering the first and second major surfaces; (c) first and second elongated conductive leads individually connected at a first end thereof to the layers of conductive material on the first and second major surfaces; (d) a layer of a material for changing the thermal mass of the sensor adhered to the layer of conductive material on at least one of the first and second major surfaces, and coextensive with the predetermined shape configuration of the film; and (e) a layer of adhesive on an exposed surface of the layer of material for changing the thermal mass of the sensor for adhering the sensor to a subject's upper lip with the elongated tab adapted to be affixed to the base of the subject's nasal septum.
