The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project concerns the most common problems with complex prosthetic hands: lack of robustness, lack of waterproofing, lack of sensory feedback, and high cost. This project will advance the development of waterproof multi-articulated hands with a touch feedback system, offering an affordable solution to restore confidence and independence to over 10 million amputees worldwide.This Small Business Innovation Research (SBIR) Phase II project will extend the work done in Phase I to develop an affordable, robust myoelectric prosthetic hand that provides natural, compliant grasps with pressure feedback to users. The work in this proposal will involve advanced mechanical design techniques necessary for waterproofing a multi-articulated prosthetic hand. Additionally, the project will advance the development of a variable grip strength, semi-automatic contact reflex system to improve the range of manipulation tasks possible with upper limb prosthetic devices. Technical tasks include: 1) development of contact reflexes through integration of position control, pressure sensing interface, and speed control for both fine, compliant manipulation of delicate objects and gross manipulation of objects requiring high grip force; 2) waterproofing to an IP67 rating, a significant technical challenge because of the many potential points of ingress and required level of manufacturing precision; 3) the mobile application user interface; and 4) standardization for manufacturing at scale.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) 第二阶段项目的更广泛影响/商业潜力涉及复杂假手最常见的问题：缺乏坚固性、缺乏防水、缺乏感官反馈和高成本。该项目将推进带有触摸反馈系统的防水多关节手的开发，提供一种经济实惠的解决方案，帮助全球超过 1000 万截肢者恢复信心和独立性。这个小型企业创新研究 (SBIR) 第二阶段项目将扩展第一阶段的工作，开发一种经济实惠、坚固的肌电假手，为用户提供自然、顺从的抓握和压力反馈。该提案中的工作将涉及多关节假手防水所需的先进机械设计技术。此外，该项目还将推进可变握力、半自动接触反射系统的开发，以改善上肢假肢装置可能执行的操作任务范围。技术任务包括：1）通过集成位置控制、压力传感接口和速度控制来开发接触反射，以实现对精致物体的精细、柔顺操纵和需要高抓力的物体的粗略操纵； 2) 防水等级达到IP67，这是一项重大的技术挑战，因为存在许多潜在的进入点和所需的制造精度水平； 3）移动应用程序用户界面； 4) 大规模制造标准化。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
