摘要： A device, system, and method for measuring torque, comprising an acoustic wave device removably attached to a rotatable shaft by a variably-shaped retainer, wherein removal of the acoustic wave device with the variably-shaped retainer facilitates servicing and replacement of the torque measurement device. The acoustic wave device can be removably attached to the rotatable shaft by using one or more connectors. Other acoustic wave devices such as acoustic wave resonators, surface acoustic wave delay lines, surface acoustic wave filters, and surface transverse waves can also be removably attached to the rotatable shaft to measure torque.

摘要： A magneto-elastic torque sensor and system include a substrate and a magneto-elastic sensing component formed from or on the substrate. The magneto-elastic sensing component and the substrate together form a magneto-elastic torque sensor, which when subject to a stress associated with a torque, shifts a characteristic frequency thereof linearly in response to the torque, thereby inducing a pathway by which magneto-elastic energy is coupled to excite vibrations in a basal plane of the magneto-elastic sensor, thereby generating torque-based information based on a resonant frequency thereof.

摘要： Many mechanical systems contain rotating parts used to transfer power from one part of the system to another. The system's efficiency and longevity can be increased by measuring the speed and loading of the rotating parts. Passive wireless sensors are ideal for instrumenting rotating parts because they require no connecting wires and no stored energy. The sensor measurements contain read errors when the stationary interrogation circuit and the rotating sensor are not ideally aligned. The read errors are a function of the angular offset between the stationary interrogation circuit and the passive sensor. As such, the read errors are deterministic. A measurement of the angular offset between the stationary interrogation circuit and the passive sensor is used to determine a correction factor that cancels out the read error to produce a compensated sensor signal.
摘要翻译：许多机械系统包含用于将电力从系统的一部分传递到另一部分的旋转部件。通过测量旋转部件的速度和载荷可以提高系统的效率和寿命。被动无线传感器是仪器旋转部件的理想选择，因为它们不需要连接线，也不需要存储能量。当固定询问电路和旋转传感器不理想地对准时，传感器测量包含读取错误。读取错误是静态询问电路和无源传感器之间的角度偏移的函数。因此，读取错误是确定性的。使用静态询问电路和无源传感器之间的角度偏移的测量来确定校正因子，其消除读取误差以产生经补偿的传感器信号。
