DESCRIPTION (provided by applicant): Innovations in battery technology and microelectronics are now finding wide acceptance in the design of new prosthetic and orthotic appliances, while the actuators used to produce motion and force in these devices remain essentially unimproved. The overall goal of this multi-phase, expanded SBIR project is to adapt a new class of "active" materials--developed to efficiently convert electrical energy directly into motion and force for aircraft and spacecraft applications--into a technically advanced "bioactuator." Specifically designed for high-performance prosthetic devices such as hands, wrists, elbows, and shoulders, these novel bioactuators will also allow clinicians to create a new generation of "intelligent," "power-assisted" orthotic braces and supports that are not currently feasible. In Phase I, active material actuator capsules will be designed and integrated into additional hardware needed to drive practical appliances. Extensive functionality and reliability testing will be conducted on a prototype device to validate its performance and to make a determination of overall feasibility for continued development in Phases II and II. Successful completion of these multiple phases of work is expected to yield a family of bioactuators-each providing different output characteristics required for various appliances, but all tailored to provide the natural appearance and wide-ranging functionality that users desire in synthetic hand and limb replacements. These robust new bioactuators are anticipated to replace the fragile micrometer and gear-based devices that represent the current state of the art by offering much greater reliability, smaller size, lower weight, and lower overall cost to users. Their substantially improved performance and flexibility will allow clinicians to create prosthetic and orthotic appliances offering the comfort, natural appearance, and functionality long sought by users. In addition, the compact nature of active materials will be fully exploited to create small appliances ideally suited to children's functional needs.

描述（由申请人提供）：电池技术和微电子学的创新现已在新型假肢和矫形器的设计中得到广泛接受，而用于在这些设备中产生运动和力的执行器基本上仍未得到改进。这个多阶段、扩展的 SBIR 项目的总体目标是将新型“活性”材料（开发用于有效地将电能直接转化为飞机和航天器应用的运动和力）转变为技术先进的“生物致动器”。 ”这些新型生物执行器专为手、手腕、肘部和肩部等高性能假肢设备而设计，也将使临床医生能够创造出目前尚不可行的新一代“智能”、“动力辅助”矫形支架和支架。 在第一阶段，活性材料执行器胶囊将被设计并集成到驱动实际设备所需的附加硬件中。将在原型设备上进行广泛的功能和可靠性测试，以验证其性能并确定第二阶段和第二阶段继续开发的总体可行性。成功完成这些多个阶段的工作预计将产生一系列生物执行器，每个生物执行器都提供各种设备所需的不同输出特性，但所有这些都经过定制，以提供用户在合成手和肢体替代物中所需的自然外观和广泛的功能。 这些强大的新型生物执行器预计将取代脆弱的千分尺和基于齿轮的设备，这些设备代表了当前的技术水平，为用户提供更高的可靠性、更小的尺寸、更轻的重量和更低的总体成本。它们显着提高的性能和灵活性将使临床医生能够制造出用户长期以来寻求的舒适性、自然外观和功能性的假肢和矫形器。此外，将充分利用活性材料的紧凑特性来制造最适合儿童功能需求的小家电。
