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
【課題】感圧発電装置全体の発電効率が良く、良好な歩行感を呈し、衝撃力等から感圧発電装置を保護でき、敷設面の状態（凹凸や不陸の有無）を選ばないで敷設できる発電床材を提供する。【解決手段】上面体１と、下面体２と、該上面体と該下面体を接合する接合壁３と、該上面体と該下面体と該接合壁とで形成される収納部４に配置された一以上の感圧発電装置５とを備え、下面体２が可撓性を有し、下向きに突出する凸部６を備えている構成の発電床材とする。上面体２に歩行圧力が加えられて発電床材が下方に移動すると、下面体２の凸部形成部分とその周辺部分が相対的に上方に撓み変形して感圧発電装置５を上面体１と下面体２で挟圧し、その圧力変動で効率良く発電する。【選択図】図２
