This Small Business Innovation Research Phase I project will develop a self-sensing piezoelectric actuator. The piezoelectric actuator will act at the same time as the sensor that will provide information to the actuators and as its own actuator. No separate sensor is needed. The self-sensing piezoelectric actuator uses an unconventional impedance approach for both dynamic (AC) and static (DC) force measurements By using piezoelectric materials, the load sensor will have a much wider dynamic range than those of conventional strain gage sensor. The simplicity in structure and electronic circuitry have made this design inexpensive, when compared to crystal resonator pressure sensors, and feasible for a wide range of applications in both sensing and control industries. During Phase I, a pre-prototype self-sensing and actuating unit will be developed for the proof of concept. A variety of targeted tests will be carried out in this phase to test and examine the accuracy and limitations of the innovation. Commercial applications include machine components; intelligent structures, intelligent self-acting machine components including bearings and seals, high-precision positioning devices, advanced electronic consumers goods, toys.

该小型企业创新研究第一阶段项目将开发一种自感应压电执行器。 压电致动器将与传感器同时工作，该传感器将向致动器提供信息并作为其自己的致动器。不需要单独的传感器。 自感应压电执行器采用非常规阻抗方法进行动态（AC）和静态（DC）力测量。通过使用压电材料，负载传感器将具有比传统应变计传感器更宽的动态范围。与晶体谐振器压力传感器相比，结构和电子电路的简单性使得该设计成本低廉，并且适用于传感和控制行业的广泛应用。在第一阶段，将开发预原型自感知和驱动单元以进行概念验证。 这一阶段将进行各种有针对性的测试，以测试和检验创新的准确性和局限性。商业应用包括机器部件；智能结构、包括轴承和密封件在内的智能自动机械部件、高精度定位装置、先进电子消费品、玩具。
