智能凝胶微执行器及其在光学器件中的应用

In this project, the properties of hydrogel were investigated by optical techniques, and the applications of hydrogel in optical devices and systems were explored. Two optical measurement methods, laser interferometry and laser beam refraction technique were designed to in situ monitor the gelation of hydrogel and the diffusion processing of molecules in hydrogel. The laser interferometry offers high measurement precision, and the laser beam refraction technique is simple and with cheap instruments, the precision can satisfy the requirement of measurements. For the applications of hydrogels, acted as sensing elements, hydrogels were combined with fiber grating to perform salinity sensors. The sensitivity of this kind of sensors can be improved by etching clad layer of fiber grating to reduce its stress. By modify the structure of hydrogel, this new kind of fiber sensors can be used to detect other physical or chemical quantity.
