Published: Aug. 19, 2024

Abstract Flexible robotic systems (FRSs) and wearable user interfaces (WUIs) have been widely used in medical fields, offering lower infection risk shorter recovery, supporting amiable human–machine interactions (HMIs). Recently, soft electric, thermal, magnetic, fluidic actuators with enhanced safety compliance innovatively boosted the use of FRSs WUIs across many sectors. Among them, hydraulic offer great speed, low noise, high force density. However, they currently require bulky electric motors/pumps, pistons, valves, rigid accessories, complex controllers, which inherently result cost, adaptation, setups. This paper introduces a novel fibrous syringe architecture (SFSA) consisting two or more hydraulically connected artificial muscles that enable electricity‐free actuation, motorless control, built‐in sensing ability for WUIs. Its capabilities are experimentally demonstrated various applications including teleoperated flexible catheters, cable‐driven continuum arms, In addition, its abilities to detect passive active touch, surface texture, object stiffness also proven. These excellent results demonstrate feasibility using current‐free motor‐less control approach WUIs, enabling new methods actuation field.
