Investigation on Energy Output Performance of IPMC Optical-Controlled Composite Driving Based on PLZT Ceramic

Abstract

 Ionic polymer-metal composite (IPMC), as an intelligent material, exhibits advantages such as rapid responsiveness, large deformation angles, and high flexibility, leading to its extensive application in biomimetic machinery, biomedicine and other fields. In this paper, based on the previous proposed IPMC optical-controlled composite driving method under lanthanum-modified lead zirconate titanate (PLZT) ceramic configuration, the output energy characteristic is analyzed by establishing a novel model and conducting a series of experiments. The analysis and experimental results show that under different light intensities, the driving force and output deformation of IPMC with varying dimensions exhibit similar trends, both increasing gradually and reach a maximum value. Furthermore, the deformation curves of IPMC driven by light source are consistent with those driven by direct current, confirming that IPMC under light excitation also possesses stable and excellent energy output properties. Therefore, the research on the energy output of IPMC optical-controlled composite driving not only provides deeper theoretical guidance for its application in flexible driving area, but also promotes the vigorous development of IPMC in other innovative technological fields.
