摘 要：Various soft actuators have been investigated to overcome the drawbacks of conventional solid machines and explore the applications of soft *** particular,and because they are expected to be applicable in minimally invasive medicine because of their safety,soft inflatable microactuators using an actuation conversion mechanism from balloon inflation to bending motion have been proposed for high-output bending *** microactuators could be applied to create an operation space by safely moving organs and tissues;however,the conversion efficiency could be further *** study aimed to improve conversion efficiency by investigating the design of the conversion *** contact conditions between the inflated balloon and conversion film were examined to improve the contact area for force transmission,with the contact area dependent on the length of the contact arc between the balloon and force conversion mechanism and on the amount of balloon *** addition,surface contact friction between the balloon and film,which affects actuator performance,was also *** generated force of the improved device is 1.21 N at 80 kPa when it bends 10 mm,which is 2.2 times the generated force of the previous *** improved soft inflatable microactuator is expected to assist in performing operations in a limited space,such as in endoscopic or laparoscopic operations.
