SBIR Phase I: Advanced Prosthetic Hand

这项小型企业创新研究(SBIR)第一阶段研究项目将开发一种基于上下文的反射控制假手的概念设计。这项工作将为灵巧假手的全面开发奠定基础，在该假手上，将基于一套传感器，包括姿势、接近、手指扭矩和肌电传感器，在假肢上局部实施自反式手运动控制。这将解放用户以自然和直观的方式专注于更高级别的功能控制。该项目的研究目标是(1)选择最佳运动学，在灵活性与成本、重量和耐用性之间进行权衡，(2)开发反射控制算法，(3)提出一个完整的概念设计，可以在第二阶段进一步开发和测试。该项目将在上肢截肢和先天性出生缺陷患者使用的假肢领域进行商业应用。假手的开发有望改善仅在美国每年就有大约1万名上肢截肢患者的生活质量和正常生活，以及数千名患有先天性出生缺陷的患者。国际社会也将同样受益。

This Small Business Innovation Research (SBIR) Phase I research project will develop a conceptualdesign for a context-based reflex-controlled prosthetic hand. This work would set the stage for full development of a dexterous prosthetic hand in which the reflexive hand motor control would be implemented locally on the prosthetic based on a suite of sensors, including pose, proximity, finger-torque, and myo-electric sensors. This would free the user to focus on higher-level functional control in a natural and intuitive way. The research objectives of this project are (1) to select optimal kinematics, trading off dexterity with cost, weight, and durability, (2) to develop the reflex control algorithm, and (3) to propose a complete conceptual design that can be further developed and tested in Phase II.The commercial application of this project will be in the area of prosthetics for use by people with upper limb amputation and congenital birth defects. Development of a prosthetic hand promises to improve the quality and normalcy of life for the roughly 10,000 patients of upper-limb amputation annually in the United States alone as well as the thousands more suffering from congenital birth defects that leave the person without a hand. The international community will likewise benefit as well.
