文中研究了聚合物基双层悬臂梁在光强和温度变化的激励下的挠度特性,并利用建立的数学模型通过采用M atlab程序进行了模拟和优化。实验得出:在热激励下聚合物(PMMA)悬梁镀金以及悬梁和金属膜厚度比值为0.1时最优化;在光激励下聚合物悬梁镀铬以及悬梁和金属膜厚度比值为0.03时最优化。研究为制作聚合物双层传感器的研制提供了理论分析和优化设计的基础。

The bi-metallic micro-cantilevers can exhibit static defection as a result of thermal effects. This paper presented the performance of the biomaterial polymeric-based cantilever excited by the temperature and light. The experiment shows that the optimization result of cantilever excited by the heat is that gold is coated and the thickness rate is 0.1. And the optimization result of cantilever excited by the light is that chromium is coated and the thickness rate is 0. 03. The research applied the basis for the theory analysis and optimization of the invention of the novel sensors.
