Pneumatic Soft Actuators With Kirigami Skins.

Soft pneumatic actuators have become indispensable for many robotic applications due to their reliability, safety, and design flexibility. However, the currently available actuator designs can be challenging to fabricate, requiring labor-intensive and time-consuming processes like reinforcing fiber wrapping and elastomer curing. To address this issue, we propose to use simple-to-fabricate kirigami skins-plastic sleeves with carefully arranged slit cuts-to construct pneumatic actuators with pre-programmable motion capabilities.
