Abstract: There is provided a detection ring (600), the structure of which is shown in the perspective view of FIG. 13(a). The detection ring (600) is arranged so that the Z-axis is a central axis on the XY plane as shown in the side view (b), and a planar shape thereof is formed in a circular ring as shown in the bottom view (c). The detection ring (600) is structured so that four sets of detection portions (D1 to D4), each constituted with a blade spring which undergoes elastic deformation, are coupled with four sets of circular arc-shaped coupling portions (L1 to L4). A supporting substrate is arranged below the detection ring (600) and fixing points (P1, P2) arranged on the Y-axis are fixed to the supporting substrate. When force or moment to be detected is exerted on exertion points (Q1, Q2), the four sets of detection portions (D1 to D4) undergo elastic deformation.

Abstract: A tabular structure having flexibility extends from a root end portion to a distal end portion along a reference axis. The root end portion is fixed to a pedestal. Three sectioned parts are provided in the tabular structure. Weights are joined to the lower surfaces of the respective three sectioned parts. The three sectioned parts respectively have different thicknesses. As a result, spring constants are different. When vibration energy from the outside is applied to the pedestal, the weights vibrate and a bend occurs in the tabular structure. If a charge generating element such as a piezoelectric element is stuck to the tabular structure, an electric charge is generated by bending stress. A frequency band capable of generating electric power is expanded by providing a plurality of weights in the tabular structure in which the spring constants are different in each of the sectioned parts.
