“…For pneumatic and hydraulic actuators, research on the structure and functional design enables this type of actuator to achieve complex motions with simple strategies. Further, the efficiency of these actuators has been improved through the integration of motors, pumps and valves [170]. Recently, the combination of pneumatic and hydraulic actuators and textiles allows us to see new possibilities [22] which make the pneumatic/hydraulic wearable robots not limited to medical treatment and rehabilitation.…”

The booming wearable market and recent advances in material science has led to the rapid development of the various wearable sensors, actuators, and devices that can be worn, embedded in fabric, accessorized, or tattooed directly onto the skin. Wearable actuators, a subcategory of wearable technology, have attracted enormous interest from researchers in various disciplines and many wearable actuators and devices have been developed in the past few decades to assist and improve people’s everyday lives. In this paper, we review the actuation mechanisms, structures, applications, and limitations of recently developed wearable actuators including pneumatic and hydraulic actuators, shape memory alloys and polymers, thermal and hygroscopic materials, dielectric elastomers, ionic and conducting polymers, piezoelectric actuators, electromagnetic actuators, liquid crystal elastomers, etc. Examples of recent applications such as wearable soft robots, haptic devices, and personal thermal regulation textiles are highlighted. Finally, we point out the current bottleneck and suggest the prospective future research directions for wearable actuators.

“…They need to possess a high switching frequency and be capable of swiftly transitioning from fully open to fully closed positions in under 5 ms. Additionally, they should minimize pressure losses, accommodate high flow rates, and maintain a compact size [8]. However, it is worth noting that the current highest achievable switching frequencies for the fastest valves range from 50 to 150 Hz, and for very small valves, they can reach up to 1000 Hz for short-term operation [26]. These characteristics have led to use of HFSVs in the automotive industry, particularly for controlling the ABS (Anti Brake-locking System) brakes of cars and actuating wet clutches, specifically dual clutch systems, which contribute to enhancing vehicle safety [27], [28].…”

“…As a result, the pressure 𝑝 𝑛 increases above the supply pressure 𝑝 𝑠 , allowing the fluid to be redirected back to the supply line (HP) through check valve (a) [40]. Scheidl et al investigated the application of digital hydraulic buck converters in advanced casting systems to facilitate mold oscillation [26]. These converters were employed as substitutes for conventional spool valves.…”
