  • The development of microtweezers using topology optimization

抄録

<p>In this study, topology optimized microtweezers was designed and fabricated. The displacement of the tips of the microtweezers was maximized by using topology optimization based on level set method which was developed by Nishiwaki Laboratory, Kyoto University. Then, the optimized microtweezers were fabricated by using a single-photon micro stereolithography system developed by our laboratory. To prove the performance of topology optimized microtweezers, a diving system including a linear actuator, a fixed stage and a microscope was built. The movement of the tips of the microtweezers was observed while being added a load. The relationship between the gap of tips and the load was analyzed. Finally, a microparticle (diameter: 100 μm) was grasped, transported and released successfully by using the microtweezers.</p>
