    • An energy harvesting device which can produce electrical power from vibrational energy over a wide range of frequencies and a method using the same are disclosed The energy harvester (10) includes a housing (20) having opposing slots (22) A bendable substrate (30) is at least partially positioned within the housing (20) and at least extends through the opposing housing slots (22) A piezoelectric element (40) is positioned on the bendable substrate (30) and a weight(50) cooperates with the bendable substrate (30) A stopper (60) is positioned on each end of the bendable substrate (30) that extends outside the housing (20) The stoppers (60) are configured to maintain a portion of the bendable substrate (30) within the housing (20) such that the bendable substrate is freely movable within the housing (20) Vibrational energy causes collisions between the bendable substrate (30) and the housing (20) such that the forces on the piezoelectric element (40) generate power.
    • 公开了一种能够在宽频率范围内从振动能产生电力的能量收集装置及其使用方法。能量收集器(10)包括具有相对的狭槽(22)的壳体(20)。可弯曲基底(30) 至少部分地定位在所述壳体(20)内并且至少延伸穿过所述相对的壳体狭槽(22)。压电元件(40)定位在所述可弯曲基底(30)上,并且配重(50)与所述可弯曲基底 止动器(60)被配置为将可弯曲基底(30)的一部分保持在壳体(20)内部(30)上。止动器(60)被定位在可弯曲基底(30) ),使得可弯曲的衬底在壳体(20)内可自由移动。振动能量引起可弯曲衬底(30)和壳体(20)之间的碰撞,使得压电元件(40)上的力产生动力。
