Shape Memory Alloys and Shape Memory Polymers in Origami-Inspired Self-Bending Micro-Actuators

While SMAs (shape memory alloys) have established a significant presence in microscale self-folding/bending actuators for origami devices due to their mature fabrication techniques and robust performance, SMPs and SMPCs (shape memory polymers/composites) demonstrate considerable potential. Their versatility in material choice and simpler fabrication methods make them promising candidates for future research and application in microscale actuators. The ongoing advancements in both SMA and SMP technologies are likely to expand theirapplicability, paving the way for more sophisticated and efficient origami-inspired devices. Future research should focus on overcoming the fabrication challenges associated with SMAs and exploring the untapped potential of SMPs at the microscale to fully leverage their capabilities in origami-inspired micro-actuation.
