ABSTRACT:
A generally tubular flexure sensor is constituted by winding a piezoelectric element including a polymeric piezoelectric strip provided with oppositely disposed surface electrode layers on both surfaces around a central axis (helical axis) so that the surface electrode layers are disposed substantially in parallel with an extension direction of the helical axis, and combining the helically wound piezoelectric element with a detection circuit for detecting a flexural deformation of the piezoelectric element in a direction perpendicular to the helical axis. The flexure sensor allows a large degree of flexural deformation in any direction to provides a good sensitivity and can be suitably used as a fish catch signal sensor for a fishing rod.
