Design and research of micro-pump based on photo-induced bending material

Based on a photo-induced bending material which has two-way shape memory function,a novel micro-pump with valves was designed and made.Combined with material deformation principle,the micro-pump's finite element model was built by using the finite element software ANSYS,and the pumping capacity calculated by ANSYS was gained and compared with the one came from the pump prototype's experimental results,then the consistency of which validates this micro-pump design's rationality.The material application on micro-pump has some reference values for relative engineering application and the photo-induced bending effect equivalent also provides research methods for similar problems.
