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： A torque sensor system and method. An automotive engine is located opposite a torque converter, such that a shaft extends from the engine and interacts with the torque converter. A target is located between the engine and torque converter. One or more torque sensors can be integrated with one or more position sensors for detecting a position associated with the shaft, wherein the torque sensor(s) and the position sensor(s) are integrated into a single torque sensor package to thereby provide enhanced sensing of the target in association with a rotation of shaft during an actuation of the engine.

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.
