用海浪使压电材料发电美国新泽西州普林斯顿海洋动力技术公司正在研究一种从海洋获取廉价而洁净能源的方法，即把一种压电聚合物置于海浪和海流中，利用海浪和海流产生的压力和应力使压电聚合物发电。压电材料是能把机械力转变成电能的一种材料，当压电材料的分子被挤压或... Powering Piezoelectric Materials with Waves Princeton, NJ, of the United States of America, is working on a way to get cheap, clean energy from the oceans by placing a piezoelectric polymer in waves and currents, using waves and ocean currents to create pressure And the stress makes the piezoelectric polymer generate electricity. Piezoelectric material is a material that can convert mechanical force into electrical energy. When the piezoelectric material molecules are squeezed or ...
