摘要

Shape-transformable garments are an emerging field in smart textiles which provide both aesthetic adaptability and functional benefits. The proposed system consists of actuating units, each composed of an active film coated with a conductive AgNW-PEDOT:PSS electrode and a 3D-printed support frame. To optimize performance, we investigated two design parameters: the electrode thickness of the active film and the curvature radius of the support frame. Experimental results showed that the electrode fabricated with bar number 7 achieved the best balance between conductivity and flexibility. Moreover, a curvature radius of 100 mm provided the most effective actuation. Based on these optimized parameters, we demonstrated the feasibility of a self-deformable skirt by integrating four actuating units with a waist fixture and covering them with silk fabric. The proposed spreading mechanism enables reversible silhouette transformation between A-line and pencil shapes. The fabricated system demonstrated reliable silhouette transformation at a low operating power of 0.045 W with a fast dynamic response above 10 Hz. These outcomes emphasize the potential of the proposed spreading mechanism as a platform for next-generation smart garments that combine versatility and functionality.
