摘要

提出了一种利用形状记忆合金(SMA)作动器将低品位热能机电转化为电能的能量收集原型。建立了该系统的模型，并通过实验验证了SMA温度与发电机旋转角度之间的关系。实验还证明了SMA能量收集原型的循环振荡能力。能量收集原型产生10.2V的峰值电压。

Electromechanical conversion of low-grade heat into electricity with shape memory alloy actuators

An energy harvesting prototype is presented to electromechanically convert low grade heat into electricity using shape memory alloy (SMA) actuators. A model is presented for the system, and the relationship between the SMA temperature and the angle of rotation of the generator is experimentally validated. The ability of the SMA energy harvesting prototype to cyclically oscillate is also demonstrated. A 10.2V peak voltage is generated with the energy harvesting prototype.
