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.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力解决了目前缺乏市售仿生假体设备中有用的，现实的反馈。目前，截肢者没有可用的假肢设备，可以通过感觉反馈提供封闭的循环控制。没有这种类型的反馈，假体用户倾向于避免操纵某些对象，因为它们有错误处理或破坏它们的风险。因此，市场需要用于上肢假体的丰富表现力的感觉反馈系统。拟议的研究旨在开发能够通过电动刺激来反馈的设备。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用户研究，该控制器评估了该设备使用Sensation Controller部署的该设备的有效性，以完成日常操作任务。这些结果有可能将大量功能恢复到全球超过1000万个上肢截肢者，并改善其生活质量。本小型企业创新研究（SBIR）II期项目旨在通过整合能够调节强度和质量质量的控制系统来增强便携式，能富的电力电动刺激器。该刺激器的设计和控制器是独一无二的。 刺激器将整合现有的假肢手动系统。感觉控制器将调节刺激参数，以补偿电极界面之间测得的电阻的变化，从而降低了由于不适而引起的设备排斥的可能性。感觉控制器还将在整个使用过程中保持一致的感觉质量。第二阶段项目完成后，假肢技术将是一种符合医疗设备的监管标准的市场就绪的感官反馈系统。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来评估的支持，并具有更广泛的影响。
