    • A meta-material vibration energy harvester includes a housing element encapsulating a multiplicity of oscillators capable of harvesting a significant percentage of the total mechanical energy diffusely distributed throughout the vibrating structure, the harvester design resulting in a rapid transfer of mechanical energy entering it via the housing element from the element to the oscillators wherein the energy remains trapped while accumulating over an extended time, the percentage of energy transfer primarily depending on the ratios of the sum of the oscillator masses to the sum of the housing mass and of the measure of the mass of the vibrating structure and of the width of the band spanned by the oscillators to its center frequency, both the relevant measure of the vibrating structure mass and the values of the mass and frequency ratios that maximize the percentage of internal energy transfer depending on the harvesting scenario.
    • 超级材料振动能量收集器包括壳体元件,其包封多个振荡器,其能够收集漫射在整个振动结构中的总机械能的相当大的百分比,收割机设计导致经由壳体进入其的机械能的快速传递 元件从元件到振荡器,其中能量在累积超过时间的同时保持被捕获,能量传递的百分比主要取决于振荡器质量的总和与壳体质量的总和与质量的量度的比率 的振动结构和由振荡器跨越的频带的宽度到其中心频率,振动结构质量的相关度量和质量和频率比的值,其根据收获最大化内部能量转移的百分比 情景。
