Abstract:
1. A sensor, comprising: a first sheet of piezoelectric material defining first and second broad sides, and, in registry on said first and second broad sides, first, second and third nonoverlapping regions, said first sheet of piezoelectric material further defining proximal and distal ends: a first sheet of electrical conductor extending over, and in contact with, said second and third regions of said first broad side of said first sheet of piezoelectric material, and not over or in contact with said first region; a second sheet of electrical conductor extending over, and in contact with, said first and second regions of said second broad side of said first sheet of piezoelectric material, and not over or in contact with said third region; whereby that second region of said first sheet of piezoelectric material lying between said second regions of said second and third sheets of conductive material, when strained, produces a sensor voltage between said second and third sheets of electrical conductor; and first and second electrically conductive means making contact with said first and second sheets of electrical conductor, for making signals from said first sheet of piezoelectric material available as a sensor signal.
