PROBLEM TO BE SOLVED: To provide a power generating floor material that offers excellent overall power generation efficiency of a piezoelectric generator and comfort in walking, capable of protecting the piezoelectric generator from impacts and others, and may be installed regardless of a condition (irregularities and unevenness) of an installed surface.SOLUTION: A power generating floor material includes a top surface body 1, an undersurface body 2, a connecting wall 3 connecting the top surface body and the undersurface body, and one or more piezoelectric generators 5 disposed in a storage part 4 formed by the top surface body, the undersurface body, and the connecting wall. The undersurface body 2 is flexible and has a convex part 6 projecting downward. When the top surface body 2 is pressed by walking and the power generating floor material moves downward, a portion of the undersurface body 2 that forms the convex part and a portion in the surrounding are deformed by deflection relatively upward, thus press-pinching the piezoelectric generator 5 between the top surface body 1 and the undersurface body 2. Electricity is generated efficiently by the pressure fluctuation.SELECTED DRAWING: Figure 2 |
