Closed-Loop Control of Soft Active Composites

This paper presents the possibility of closed-loop regulation of position or force at features (posts) on an active composite membrane. Active composite membranes are multilayered membranes with different functions, actuation, sensing, interconnect, mechanical compliance tuning assigned to them. Here we demonstrate the ability to perform closed-loop control on an array of four posts on a membrane stamp designed for micro-transfer printing. The paper also assesses the positioning and force resolution obtaining from such membranes.
