传统外骨骼在可穿戴式人体助力和运动康复领域做出巨大贡献。然而,外骨骼仍然面临一些挑战,如质量大、结构复杂、刚度高、噪音大,且关节处有固定旋转中心,给老年人和肌肉虚弱者带来使用困难。相反,基于柔性智能材料的人工肌肉具有质量轻、结构紧凑、刚度低和静音驱动等特性,被认为是与天然肌肉最相似的材料。介电弹性体(dielectric elastomers,DE)和聚氯乙烯(polyvinyl chloride,PVC)凝胶致动应变和致动应力大,响应速度快,驱动寿命长,在可穿戴式人体助力和运动康复领域具有很大应用潜力。然而,这两种材料在这些领域少有研究。在这篇综述中,我们首先分别介绍DE和PVC凝胶的工作原理。接着,总结常用DE材料和PVC凝胶材料。然后,回顾这两种材料所需要的驱动电极和自传感系统。最后,介绍这两种材料在可穿戴式人体助力和运动康复领域的初步应用。
Traditional exoskeletons have made considerable contributions to people in terms of providing wearable assistance and rehabilitation. However
exoskeletons still have some disadvantages
such as being heavy
bulky
stiff
noisy
and having a fixed center of rotation that can be a burden on elders and patients with weakened muscles. Conversely
artificial muscles based on soft
smart materials possess the attributes of being lightweight
compact
highly flexible
and have mute actuation
for which they are considered to be the most similar to natural muscles. Among these materials
dielectric elastomer (DE) and polyvinyl chloride (PVC) gel exhibit considerable actuation strain
high actuation stress
high response speed
and long life span
which give them great potential for application in wearable assistance and rehabilitation. Unfortunately
there is very little research on the application of these two materials in these fields. In this review
we first introduce the working principles of the DE and PVC gel separately. Next
we summarize the DE materials and the preparation of PVC gel. Then
we review the electrodes and self-sensing systems of the two materials. Lastly
we present the initial applications of these two materials for wearable assistance and rehabilitation.
