The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project addresses the current lack of useful, realistic feedback in commercially available bionic prosthetic devices. There are currently no prosthetic devices available to amputees that provide closed loop control through sensory feedback. Without this type feedback, prosthesis users tend to avoid manipulating certain objects because they run the risk of handling them incorrectly or destroying them. Consequently, there is a market need for a richly expressive sensory feedback system for upper limb prosthetics. The proposed research seeks to develop a device capable of such feedback with electrotactile stimulation. The expected outcomes of this research are: a controller that can regulate both intensity and quality sensation and a user study which evaluates the effectiveness of this device deployed with a sensation controller for day-to-day manipulation tasks. These outcomes have the potential to restore a significant amount of function to over 10 million upper limb amputees worldwide and improve their quality of life.This Small Business Innovation Research (SBIR) Phase II project seeks to enhance a portable, energy-efficient electrotactile stimulator, by integrating a control system that will be able to regulate both intensity and quality of sensation. The design and controller of this stimulator are unique. The stimulator will integrate existing prosthetic hand systems. The sensation controller will modulate stimulation parameters to compensate for changes in measured resistance between the electrode-skin interface, thus reducing the likelihood of device rejection due to discomfort. The sensation controller will also maintain a consistent quality of sensation throughout usage. Upon completion of the Phase II project, the prosthetic technology will be a market-ready sensory feedback system that is compliant with regulatory standards for medical equipment.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.

该小企业创新研究 (SBIR) 第二阶段项目具有更广泛的影响/商业潜力，解决了目前商用仿生假肢设备缺乏有用、现实反馈的问题。目前还没有可供截肢者使用的假肢装置可以通过感觉反馈提供闭环控制。如果没有这种类型的反馈，假肢使用者往往会避免操纵某些物体，因为他们面临着错误处理或破坏它们的风险。因此，市场需要一种用于上肢假肢的表达丰富的感觉反馈系统。拟议的研究旨在开发一种能够通过电触觉刺激进行反馈的设备。这项研究的预期结果是：一个可以调节强度和质量感觉的控制器，以及一项用户研究，该研究评估部署有感觉控制器的该设备对日常操作任务的有效性。这些成果有可能使全球超过 1000 万上肢截肢者恢复大量功能，并提高他们的生活质量。这个小型企业创新研究 (SBIR) 第二阶段项目旨在增强便携式、节能的电触觉刺激器，通过集成一个能够调节感觉强度和质量的控制系统。该刺激器的设计和控制器是独一无二的。 该刺激器将集成现有的假肢系统。感觉控制器将调节刺激参数以补偿电极-皮肤界面之间测量的电阻的变化，从而减少由于不适而导致设备排斥的可能性。感觉控制器还将在整个使用过程中保持一致的感觉质量。二期项目完成后，假肢技术将成为符合医疗设备监管标准、可投入市场的感觉反馈系统。该奖项反映了 NSF 的法定使命，并通过利用基金会的智力优势进行评估，认为值得支持以及更广泛的影响审查标准。
