摘要
E-ACE作为压电材料的一种,因其自身具有的变形量大、比能量高等优势受到了广泛关注。针对当前能源形势危机的问题,提出了基于E-ACE材料的机械能转化为电能,从而对环境中的机械能量进行收集利用。为了研究压电材料对环境中机械能量的收集情况,对该材料的种类、发电原理、发电模式进行分析,并搭建了基于E-ACE的机械能转化为电能实验台。实验结果表明:在相同拉伸量条件下,基础偏置电压越高,发电电压越高;而E-ACE施加外力使其变形时,变形越大电容的改变量越大,从而使发电能力越强,因此基础偏置电压和拉伸量都是影响E-ACE机械能转化为电能的影响因素。
As a kind of piezoelectric material,E-ACE have received extensive attention due to their own advantages such as large deformation and high specific energy.In response to the critical issue of the current energy situation,it is proposed to convert mechanical energy based on E-ACE materials into electrical energy,so as to collect and utilize mechanical energy in the environment.In order to study the material's ability to harvest mechanical energy in the environment,The article analyzes the types of E-ACE materials,the principle of power generation,and the power generation mode,and builds an experimental platform for converting E-ACE mechanical energy into electrical energy.The experimental results show that the higher the base bias voltage,the higher the power generation voltage under the same stretching condition.However,when E-ACE is deformed by external forces,the larger the deformation,the greater the capacitance change,and the stronger the generating capacity.Therefore,both the foundation bias voltage and the stretching amount are the influential factors affecting the transformation of E-ACE mechanical energy into electric energy.
