Abstract:
A strain/electrical potential transducer includinga rigid base, an elongate stack of dielectric substance having electrical contactors arranged to be subjected to an electric potential associated with electro-deformation of the dielectric substance, a first end of the elongate stack being hinged to the base at a stack hinge position; a rigid beam hinged at a first end thereof to the base at a beam hinge position, the rigid beam being transversely spaced from the elongate stack and extending generally longitudinally with the elongate stack; a rigid connecting link extending transversely between and interconnecting opposed ends respectively of the elongate stack opposite to said first, hinged end, and of the rigid beam opposite to said first, hinged end, the configuration being such that longitudinal deformation in the elongate stack and transverse displacement in said opposed end of the rigid beam are causally connected.
