“…Wearable robots for locomotion augment able‐bodied people and assist people with mobility disabilities in activities including walking, [ 26–30 ] running, [ 31 ] and sit‐to‐stand motions, [ 18,32 ] which enable the user to begin locomotion. These devices can be used as assistive garments or as training and rehabilitative devices.…”

“…[ 33,37 ] In addition, textile‐based foam composites and meshes dampen the applied forces for wearer comfort. [ 31 ] The fluidic actuation approach implements global patterning of woven textile pouches with high tensile stiffness (described in more detail in Section 4.2) to create tailored fluidic actuators that can assist with flexion at a joint, [ 17 ] extend at a joint, [ 30,32 ] provide support through a change in material stiffness, [ 7,29 ] or implement a combination of these strategies. Few instances of “shape‐changing‐material‐based” wearable robots for locomotion have been demonstrated to date, and those developed employ few textile‐based components.…”

“…Because fluidic textile actuators rely on expansion of bladders, in addition to “pulling” as seen in cable driven systems, they are able to “push,” and are used to press up the limbs of a wearer as stabilizing structures. [ 22,32,60 ] In these actuators, textile microstructures and textile‐based patterning are leveraged to generate a wide array of functional motions for wearable robotics including contraction, extension, and bending. Graduated pressure levels within the same actuator have been used for the actuator to serve as a variable stiffness material.…”

Textiles have emerged as a promising class of materials for developing wearable robots that move and feel like everyday clothing. Textiles represent a favorable material platform for wearable robots due to their flexibility, low weight, breathability, and soft hand‐feel. Textiles also offer a unique level of programmability because of their inherent hierarchical nature, enabling researchers to modify and tune properties at several interdependent material scales. With these advantages and capabilities in mind, roboticists have begun to use textiles, not simply as substrates, but as functional components that program actuation and sensing. In parallel, materials scientists are developing new materials that respond to thermal, electrical, and hygroscopic stimuli by leveraging textile structures for function. Although textiles are one of humankind's oldest technologies, materials scientists and roboticists are just beginning to tap into their potential. This review provides a textile‐centric survey of the current state of the art in wearable robotic garments and highlights metrics that will guide materials development. Recent advances in textile materials for robotic components (i.e., as sensors, actuators, and integration components) are described with a focus on how these materials and technologies set the stage for wearable robots programmed at the material level.

Wearable robots are undergoing a disruptive transition, from the rigid machines that populated the science-fiction world in the early eighties to lightweight robotic apparel, hardly distinguishable from our daily clothes. In less than a decade of development, soft robotic suits have achieved important results in human motor assistance and augmentation. In this paper, we start by giving a definition of soft robotic suits and proposing a taxonomy to classify existing systems. We then critically review the modes of actuation, the physical human-robot interface and the intention-detection strategies of state of the art soft robotic suits, highlighting the advantages and limitations of different approaches. Finally, we discuss the impact of this new technology on human movements, for both augmenting human function and supporting motor impairments, and identify areas that are in need of further development.

“…This action, which does not pose a significant difficulty for healthy people, could be a challenge for the elderly who begin to have alterations in motor function [ 7 ]. The Sit-to-Stand test (STS) is a functional test widely used in both research and clinic, since getting up and sitting in a chair is a functional movement that is frequently repeated in daily life [ 8 , 9 ]. During its execution, basic functional abilities such as coordination, balance, range of motion and force are evaluated, as well as the ability to move the centre of mass forward from a broad support base towards a more narrow one [ 9 ].…”

Background: The use of rehabilitation protocols carried out in water has been progressively increasing due to the favorable physical properties of the water. Electromyography allows one to register muscle activity even under water. Aim: To compare muscle activity between two groups (healthy young adults (HYA) and healthy older adults (HOA)) in two different environments (dry land and aquatic) using surface electromyography during the execution of four different test/functional movements. Methods: Analytical cross-sectional study. HYA and HOA carried out four functional tasks (Step Up and Down, Sit TO Stand test, Gait Initiation and Turns During Gait) in two different environments (dry land and aquatic). Absolute and relative muscle activation was compared between each group and between each environment. In addition, the stability of the measured was calculated through a test-retest (ICC 2:1). Results: Within the same environment there were significant differences between young and older adults in three of the four functional tasks. In contrast, in the gait initiation, hardly any significant differences were found between the two groups analysed, except for the soleus and the anterior tibial. Measurement stability ranged from good to excellent. Conclusions: Level of the musculature involvement presents an entirely different distribution when the test/functional task is performed on dry land or in water. There are differences both in the relative activation of the musculature and in the distribution of the partition of the muscles comparing older and young adults within the same environment.
