However, at present, the study about piezoelectric energy collection focuses on the power supply for the MEMS ( micro electro mechanical system ). The study which is in relation to use piezoelectric materials to generate power cannot be common, it also nearly blank in domestic. 但是,目前有关压电集能的研究主要集中在为微机电系统的供电上,利用压电材料来进行发电的研究并不多见,国内这方面的研究更是接近空白。
