“…According to the TAM, perceived usefulness and ease of use are significantly correlated with the intention to use [ 25 ]. In addition to perceived usefulness and ease of use, the perceived comfort [ 26 , 30 , 31 ] and safety [ 26 , 32 ] can affect the purchase intention of products like MSC. It would be helpful to investigate how users’ perceptions of usefulness, ease of use, comfort, and safety affect their intention to use and purchase MSCs.…”

This study aimed to explore the needs and wants of older adults in the context of movement-assistive clothing (MSC), with a focus on muscle strength and posture correction. A survey was conducted to understand the needs and wants of older adults, considering aspects of functions and designs, and to evaluate the comfort, safety, ease of use, usefulness, and intention of users to purchase and use products. A total of 408 individuals aged > 65 years participated in the study. The data were analyzed using descriptive analyses, such as mean, standard deviation, percentages, Cronbach’s alpha, chi-square test, independent t-test, analysis of variance, and regression using IBM SPSS 27.0. Exploratory Factor Analysis was also conducted to test the hypotheses. Open-ended questions were extracted using major themes after color-coding. Based on the results, design recommendations were derived, including the development of pants and innerwear with casual, minimalist styles, featuring achromatic colors, and utilizing stretchy, breathable fabrics. Comfort, safety, ease of use, and usefulness emerged as critical factors influencing the purchase and use of MSC by older adults. This study aimed to establish design guidelines by understanding the needs and wants of older adults and considering the aspects of movement-assistive clothing to relieve musculoskeletal issues. Accordingly, these findings are expected to aid in the creation of wearable suits using flexible fabric artificial muscles for active musculoskeletal correction in older adults.

“…This is because the core of wearable technology that touches the body is a very important factor in ensuring a comfortable fit. 7 Wearable robots have a specific wearer and purpose for wearing them; thus, the process of evaluating clothing and solving the problems derived from them is important. 8 Recently, when developing robots that interact with humans, developers have tried to identify user needs and ergonomic elements to apply to the designs.…”

“…After the user test, participants completed the questionnaire survey using a 5-point Likert scale and open-ended questions. The questionnaire consisted of 101 measurement items, including seven questions about demographic characteristics; 40 questions about wear satisfaction by body part; 7 36 questions about subjective pressure evaluations; 33 15 questions about design satisfaction, including durability, thermal comfort, fit/stability, and cognition, which are key aspects of wearables' comfort and usability; 37,38 and three questions about purchase intention. 39 The measurement items were modified to fit to the purpose of this research (i.e.…”

The purpose of this study was to develop a clothing-type platform of wearable robots for industrial workers who usually lift loads to prevent accidents and increase their work efficiency. First, fabrics were selected through test analyses of the elongation recovery rate and tensile strength. Second, a suit-type platform embedded with electrostatic clutch band actuators was prototyped and measured the friction force, and a washing dimension change rate of the test with the platform was conducted. Third, clothing pressures were measured after the developed prototype was worn, using an air injection sensor system at nine points and with four motions. Next, subjective clothing pressure and satisfaction surveys were conducted. The study produced four major results: (a) the selected fabrics and the prototype with the electrostatic clutch actuator met the performance requirements; (b) the greatest clothing pressure occurred at the back, back waist, and back knee, where actuators were connected, and the clothing pressure was sufficient for positional stability; (c) the subjective pressure was different in each section from the actual clothing pressure measurement; and (d) participants were satisfied with the developed prototypes, and they showed willingness to purchase them. The results can help developers of wearable robots increase comfort and user satisfaction.

“…Liu et al [14] assessed comfort by measuring body pressure and established a subjective evaluation standard for comfort using the Likert scale. Subsequently, Eom et al [15] evaluated the comfort of the rehabilitation robot by measuring the surface temperature of the rehabilitation robot under two actions and using a 7-point Likert scale. Similarly, there were some studies that established comfort evaluation indicators by measuring the interaction forces between users and robots [16][17] .…”

Due to the advantages of high durability, great repeatability and task orientation, the upper extremity rehabilitation robots have become a gospel for the rehabilitation treatment of stroke patients. The evaluation system for the comfort performance of rehabilitation robots has always been a research hotspot, and how to calculate the human-robot interaction forces is a challenge for the comfort evaluation. In this article, a four degrees of freedom (4-DOFs) upper extremity robot mechanism that is kinematically compatible with the upper limb is presented. Then, taking this mechanism as the research object, an algorithm for estimating human-robot interaction forces is addressed based on Newton-Euler dynamic. Subsequently, a prototype of the proposed robot is developed, and a comparison experiment of interaction forces is carried out on the prototype. The comparative experimental outcomes indicate that the presented algorithm for calculating the human-robot interaction forces is feasible. The findings of this paper provide a prerequisite for the evaluation of the robot comfort, which is of great practical significance.
