“…The number of times work clothes were washed per week was three times ( n = 19, 31.70%) and twice ( n = 16, 26.70%). Industrial workers can sweat a lot and are often exposed to pollution, 19–27 so it is recommended to use materials that dry quickly after washing and maintain functions after repeated washing.…”

The aim of this study was to develop suits for upper-body wearable robots that can satisfy the needs of industrial workers. Firstly, a preference survey was conducted to understand the workers’ preferences in terms of design and functions. Secondly, designs were developed and prototyped after performance tests of the materials used, including washing dimension-change rates and resilience for the stability of sensors and actuators. Thirdly, a satisfaction survey was conducted to evaluate the developed designs. The major results were as follows: (a) the most preferred function was assisting movements while lifting heavy objects or patients from the floor or at lower levels below the waist; (b) the preferred design features included waist-length shirts without collars, a style that can be worn outside, black or blue designs, wicking fabrics, and flexible materials; (c) four designs were developed and prototyped after confirming the fabric and clothing performance tests; (d) upon evaluating design and function satisfaction, more than 73% of participants were satisfied with the four designs, and 85% wanted to wear them. Design D was the most satisfactory in terms of material mapping details (featuring seams along muscular body lines and added three-dimensional (3D) patterns on the elbows). Design B was the most satisfactory regarding purchase and use/wearing. This was the design with tapered lines for raglan sleeves and horizontally cut lines on the shoulders. Participants expected Design C, with seams along muscular body lines and 3D patterns on the elbows, to easily suit patients and nurses. This research will be helpful when developing suits for upper-body movement-assistive wearable robots.

During the past decade, wearable devices such as exoskeletons have gained popularity [1] in different fields, such as the military, [2] industry, [3] and rehabilitation. [4] In the latter, rehabilitation exoskeletons are used to restore or maintain the functionality and mobility of people with physical disabilities. [5] These are receiving greater attention as the number of people with disabilities affecting physical performance will increase in the following decades as the population ages and individuals live longer with noncommunicable conditions (e.g., cerebral palsy, stroke, acquired brain injuries, and muscular dystrophies). [6][7][8] Most current exoskeletons use electric motors and rigid links to realize actuation and often have heavy and bulky designs that are difficult to safely wear outside clinical facilities. [9] Hence, researchers in this area are working to develop soft wearable rehabilitation robots (SWRRs), featuring soft actuators that are agreeable to the users as they have increased compliance, adaptability, comfort, safety, and less weight. [10][11][12] Currently, SWRR relies mainly upon two soft robotic technologies, cable-driven and fluidic actuators. For a cable-driven system, the wire is embedded into clothes or tubes and attached to an anchor point. The other side of the wire is connected to an electric motor to generate the desired movement and force by pulling the cable [13,14] (Figure 1a). Alternatively, in fluidic actuation (Hydraulic/Pneumatic), a pressurized fluid is inserted into a chamber made of highly deformable material to generate a displacement [11,15,16] (Figure 1b). However, these require large and heavy external pumps and valves to compress the fluid. [17] Unfortunately, cable-driven and fluidic actuation need cumbersome components (e.g., electric motors, pumps, and valves) to work, compromising the portability of the systems when used in daily life. [18] Therefore, in recent years, research has been committed to developing new actuator technologies that can overcome the drawbacks of the current actuators used in SWRR. These technologies include artificial muscles based on smart materials (AMSMs). AMSMs are soft actuators composed primarily of material with a low Young's modulus similar to that of soft biological materials (10 ^4-10 ^9 Pa) that can sense and directly convert physical stimulus (e.g., light, electrical, heat) into physical displacement. [19][20][21][22][23] Some examples of smart materials are shape-memory alloy (SMA), [24] dielectric elastomer actuators (DEAs), [25] ionic polymer-metal composites (IPMC), [26] shapememory polymers (SMPs), [27] and twisted and coiled polymer actuators (TCPs). [28] Due to their inherent properties and manufacturing processes, AMSM can be fabricated in various shapes, allowing them to be embedded into flexible and deformable wearable devices. [29][30][31][32] Furthermore, it is possible to fabricate robots with a relatively small weight and volume as they present a power density comparable to the skeletal muscles. [33] Neverthe...
