The broader impact/commercial potential of this I-Corps project is the development of a rapidly customizable, 3D printed, powered hand orthosis to help stroke survivors regain their manual dexterity and independence. Stroke is a debilitating, life-changing event. Part of the brain dies, and the mind-body connection is lost. Stroke survivors experience problems such as lack of hand control, including difficulties grasping and opening, and instability. These problems leave them dependent on others for some of the most basic tasks. Current medical devices are inadequate. The devices come in limited sizes and either prevent motion or constrain the hand to unnatural movement. A custom-sized orthosis could mitigate all these problems, providing a better fit and more effective recovery. Automating the customization process may reduce the risk of design/fitting/fabrication error by the orthotist, as well as the need for a skilled technician, in addition to time and monetary costs. The proposed technology may benefit the orthotics industry, making custom assistive devices more accessible to patients and enabling them to reach new levels of independence.This I-Corps project is based on the development of a rapidly customizable, 3D printed, powered hand orthosis. Prior to design, anatomical data was analyzed to determine mathematical relationships between hand length and width and individual joint and bone positions. The intellectual merit of this innovation involves several key components including a smart computer aided design (CAD) package based on the anatomical relationships to generate custom size part files that can be rapidly 3D printed, reducing the need for a skilled orthosis technician. In addition, flexible joints will enable multiaxial mobility. An active, intelligent control will provide the needed assistance for users to perform activities of daily living independently. Currently, a preliminary CAD package and orthosis prototype have been developed. The primary design challenge remaining is how to fit the entire actuation system within the anthropometric envelope without sacrificing assistive capabilities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是开发快速定制的3D印刷，动力的手矫形器，以帮助中风幸存者恢复其手动敏捷性和独立性。 中风是一个令人衰弱的，改变人生的事件。大脑的一部分死亡，而思维体连接也丢失了。 中风幸存者经历了缺乏手部控制的问题，包括困难抓住和开放以及不稳定。 这些问题使他们取决于其他问题。 当前的医疗设备不足。 设备的尺寸有限，可以防止运动或限制手运动。 定制的矫形器可以减轻所有这些问题，从而提供更好的健康和更有效的恢复。 自定义过程自动化可能会降低矫正师设计/配件/制造错误的风险，以及对熟练技术人员的需求，除了时间和货币成本。 拟议的技术可能会使矫正行业受益，从而使患者更容易获得定制的辅助设备，并使他们能够达到新的独立水平。此I-Corps项目基于开发可快速自定义的3D印刷，动力的手矫形器。 在设计之前，分析了解剖学数据，以确定手长，宽度以及单个关节和骨位置之间的数学关系。 这项创新的智力优点涉及几个关键组件，包括基于解剖学关系的智能计算机辅助设计（CAD）软件包，以生成可以快速打印3D的自定义尺寸零件文件，从而减少了对熟练的矫形器技术人员的需求。 此外，柔性关节将实现多轴迁移率。 积极的智能控制将为用户提供所需的帮助，以独立进行日常生活的活动。 当前，已经开发了初步的CAD包和矫形器原型。 剩下的主要设计挑战是如何在人体测量范围内适应整个致动系统，而无需牺牲辅助能力。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估来审查标准的。
