“…A soft muscle glove containing SMA wires has been developed to replicate the functionalities of a human hand. The glove can achieve functional range of motion of the human hand and can perform a wide range of grasp types (Figure 4b) [43]. A suit-type wearable robot (STWR) containing SMA fabric muscle has been developed to assist the muscular strength of wearers [44].…”

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 or accessories, or tattoos 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 the 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.

“…It is not necessary to use a tendon/cable–pulley system to imitate the natural motion of a finger. Yao et al [74] used SMA springs to actuate the finger into flexion or extension and to retain its resting position. The iH glove (Figure 2c) uses a cable-actuated wearable glove to support patients in performing ADL [59].…”

“…Another innovative biomimetic design can be seen in the soft muscle glove (Figure 2e). This device uses SMA springs and tendon actuators to control the motion of the wearable glove, and its motion is similar to natural hand motion [74].…”

“…In 2017, eight articles reported the use of pneumatic/hydraulic actuators [9,14,26,33,46,49,76,77], while seven articles presented the use of a tendon/cable-driven system [23,52,59,72,73,74,75]. One of the unique designs uses SMA springs to mimic the function of a finger endoskeleton muscular tendon during flexion and extension motion [74]. The glove weighs only 85.03 g, which is considerably less than many other five-fingered tendon/cable-driven exoskeletons.…”

Moving toward Soft Robotics: A Decade Review of the Design of Hand Exoskeletons

et al. 2018

View full text Add to dashboard Cite

Soft robotics is a branch of robotics that deals with mechatronics and electromechanical systems primarily made of soft materials. This paper presents a summary of a chronicle study of various soft robotic hand exoskeletons, with different electroencephalography (EEG)-and electromyography (EMG)-based instrumentations and controls, for rehabilitation and assistance in activities of daily living. A total of 45 soft robotic hand exoskeletons are reviewed. The study follows two methodological frameworks: a systematic review and a chronological review of the exoskeletons. The first approach summarizes the designs of different soft robotic hand exoskeletons based on their mechanical, electrical and functional attributes, including the degree of freedom, number of fingers, force transmission, actuation mode and control strategy. The second approach discusses the technological trend of soft robotic hand exoskeletons in the past decade. The timeline analysis demonstrates the transformation of the exoskeletons from rigid ferrous materials to soft elastomeric materials. It uncovers recent research, development and integration of their mechanical and electrical components. It also approximates the future of the soft robotic hand exoskeletons and some of their crucial design attributes.
