PDMS-based dual-channel pneumatic micro-actuator

This paper presents a monolithic novel polydimethylsiloxane-based dual-channel bellows-structured pneumatic actuator, fabricated through a sacrificial molding technique. A finite element analysis was performed to find the optimal structure and analyze the bending performance of the square-bellows ac...
