项目摘要

WAM is a project which started from asking a question about what would make a transformational difference to someone who is experiencing difficulties in walking. The answer was to be able to walk without visible (or audible) assistance. Following some initial work in an EPSRC project called RELEASE, WAM is starting on the road to developing just this sort of assistive technology: an exoskeleton that can be worn and that can also act as a muscle so that it can support the whole walking cycle, providing support and control to the user and enabling them to walk otherwise unaided. We have selected some of the likely possibilities from those explored during the RELEASE project and WAM will develop these further, combine them and test them against the strength, stiffness, flexion and strain requirements of the walking process. Three technologies will be explored in parallel: (1) using Vanadium Oxide (V2O5) as a chemical actuator, (2) using magnetic gels as a dynamic controllable mechanism and (3) using interlockable ceramic tiles as a surface medium. V2O5 is able to flex when exposed to an electrostatic potential and can exhibit strength (about 10 times the strength found in skeletal muscle) so this would seem to be a useful substance to use as the basis for an actuator. Macroporous magnetic gels can be used to compress rapidly under a magnetic field to deliver drugs (by squeezing the drugs from the pores as the material compresses under the influence of an induced magnetic field). Interlockable ceramic tiles can provide the stiffness needed for the rigidity needed by a skeleton, but once unlocked an allow the structure to bend in a required direction. These will be tested separately and in combination to see if the V2O5 working with the magnetic gel could act as a sufficiently strong actuator and key for the locking/unlocking mechanism so that the material can demonstrate sufficient strength, stiffness and strain capabilities to be worth scaling up in a future project to assist walking. Other possibilities would also be available from such material - it does not have to be used only for walking as it could be used for other joints which can need support but which also need to bend - elbow, wrist, ankle as well as knee are all candidates for such support. Also, it might provide an interesting support where it is desirable to make the assistance variable - when the person needs support and when they would benefit from being encouraged to take on the activity themselves. A variably flexible material of this sort would therefore be of use in conditions such as limb fractures (where absolutely fixed support is essential at one point on the process, but rehabilitation of associated muscles would be beneficial as the facture is healing, but is still weak, before the fixed support can be removed) or conditions such as Carpal Tunnel Syndrome where support needs might vary. While the technological work is underway we will be working with a patients' group and a group of clinicians to understand more about what end users might be looking for in their assistive technology and how this particular type of support might be useful for them. It is important to realise that this is a novel way of providing dynamic support for activities such as walking and thus there is a sense of all sides needing to understand how best to use the technology as it emerges from the laboratory. The present project will not deliver the full working prototype of a walking support system, but it will develop, test and show what can be done in terms of the material and its control system and the extent to which this approach to actuation of locomotory support could be achieved. The final tests will show how much stiffness and strength it can deliver and thus whether or not this is the right way to proceed in further projects.
WAM是一个项目,它从问一个问题开始,这个问题是关于什么会对行走困难的人产生变革性的影响。答案是能够在没有可见(或可听)辅助的情况下行走。在EPSRC的一个名为RELEASE的项目中进行了一些初步工作之后,WAM开始开发这种辅助技术:一种可以穿戴的外骨骼,也可以作为肌肉,这样它就可以支持整个步行周期,为用户提供支持和控制,使他们能够在没有帮助的情况下行走。我们已经从RELEASE项目中选择了一些可能的可能性,WAM将进一步开发这些可能性,将它们联合收割机结合起来,并根据行走过程的强度、刚度、屈曲和应变要求对其进行测试。将同时探索三种技术:(1)使用氧化钒(V2 O 5)作为化学致动器,(2)使用磁性凝胶作为动态可控机制,(3)使用可互锁瓷砖作为表面介质。V2 O 5在暴露于静电势时能够弯曲,并且可以表现出强度(约为骨骼肌中发现的强度的10倍),因此这似乎是用作致动器的基础的有用物质。大孔磁性凝胶可用于在磁场下快速压缩以递送药物(当材料在感应磁场的影响下压缩时,通过从孔中挤压药物)。可互锁陶瓷砖可以提供骨架所需的刚度所需的刚度,但是一旦解锁,就允许结构在所需方向上弯曲。这些将单独和组合进行测试,以查看与磁性凝胶一起工作的V2 O 5是否可以作为锁定/解锁机构的足够强的致动器和钥匙,以便材料可以表现出足够的强度,刚度和应变能力,值得在未来的项目中扩大规模以帮助行走。从这种材料也可以获得其它可能性-它不必仅用于行走,因为它可以用于可能需要支撑但也需要弯曲的其它关节-肘、腕、踝以及膝都是这种支撑的候选者。此外,在需要使援助可变的情况下-当有关人员需要支助时,以及当鼓励他们自己从事活动将使他们受益时,它可能提供一种令人感兴趣的支助。因此,这种柔性材料可用于诸如肢体骨折的情况(其中在过程中的某一点绝对固定的支撑是必要的,但相关肌肉的康复将是有益的,因为骨折正在愈合,但在固定支撑可被移除之前仍然很弱)或诸如腕管综合征的情况(其中支撑需求可能变化)。在技术工作进行的同时,我们将与一个患者小组和一组临床医生合作,更多地了解最终用户可能在他们的辅助技术中寻找什么,以及这种特殊类型的支持如何对他们有用。重要的是要认识到,这是一种为行走等活动提供动态支持的新方法,因此各方都需要了解如何最好地使用该技术,因为它来自实验室。本项目将不会提供步行支撑系统的完整工作原型,但它将开发,测试和展示在材料及其控制系统方面可以做些什么,以及这种驱动运动支撑的方法可以实现的程度。最终的测试将显示它可以提供多大的刚度和强度,从而确定这是否是在未来项目中进行的正确方法。
