Sensitive synthetic dry adhesives for pick and place application in MEMS

我们建议将新型生物启发粘合剂集成到机器人拾取和放置系统的末端执行器中，用于MEMS和微流体的组装和包装。MEMS或微流体技术商业化的最具挑战性的问题之一是微制造管芯的最终封装。每个单独的芯片必须小心地放置在包含电气或微流体互连的封装中，密封和粘合。传统上，拾取和放置机器人使用主动吸力来将管芯保持在适当位置，同时将它们移动到适当位置，但这需要主动气动装置，复杂的末端执行器尖端，并且可能损坏具有自由移动部件的设备，如MEMS的情况。不能使用普通的粘合剂，因为它们不可切换，传统的粘性材料会在MEMS表面留下残留物

We are proposing the integration of novel bio-inspired adhesives into the end-effectors of robotic pick and place systems for assembly and packaging of MEMS and microfluidics. One of the most challenging issues for commercialization of MEMS or microfluidics is the final packaging of the microfabricated die. Each individual die must be carefully placed in a package containing electrical or microfluidic interconnections, sealed and bonded. Traditionally, pick and place robots have used active suction to hold die in place while moving them into position, but this requires active pneumatics, a complex end effector tip and can potentially damage devices with freely moving parts, as in the case with MEMS. Normal adhesives cannot be used because they are not switchable, and traditional tacky materials will leave residues on the surfaces of MEMS
