ABSTRACT:
A mechanical/thermal stress transducer consisting of a piezo-pyroelectric material in electrical communication with a electroluminescent material, an electrode positioned between the piezo-pyroelectric material and the electroluminescent material forms the electrical communication at disjunct intervals so that the luminous intensity of light emitted by the electroluminescent material at any point is related to the mechanical/thermal stress acting at that point on the transducer. Selected applications of the transducer are included.
