Micromachines - MDPI - Publisher of Open Access Journals

Inflatable soft microactuators typically consist of an elastic material with an internal void that can be inflated to generate a deformation. A crucial feature of these actuators is the shape of ther inflatable void as it determines the bending motion. Due to fabrication limitations low complex void geometries are the de facto standard severely restricting attainable motions.
