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： A plurality of acoustic wave sensing devices can be provided, which are mechanically simulated for implementation upon a quartz wafer substrate. The quartz wafer substrate is appropriately etched to produce a quartz diaphragm from the quartz wafer substrate. A plurality of torque SAW sensing resonators can then be located upon the quartz wafer substrate, which is based upon previously mechanically simulated devices for implementation upon the substrate, together with a quartz cover to thereby produce a quartz torque sensor package from the quartz wafer substrate.

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： Sensor systems and methods are disclosed herein, including a sensor chip, upon which at least two surface acoustic wave (SAW) sensing elements are centrally located on a first side (e.g., front side) of the sensor chip. The SAW sensing elements occupy a common area on the first side of the sensor chip. An etched diaphragm is located centrally on the second side (i.e., back side) of the sensor chip opposite the first side in association with the two SAW sensing elements in order to concentrate the mechanical strain of the sensor system or sensor device in the etched diagram, thereby providing high strength, high sensitivity and ease of manufacturing thereof.

摘要： A torque sensor is disclosed based on a SAW die configured on a surface of a plate, and an isolator formed from a flexible material. The isolator is rigidly mounted to the plate, such that the isolator flexes when a force perpendicular to the surface of the plate are applied while transferring a torque that is applied within a plane of the plate to the SAW die, thereby eliminating or minimizing the effect on the SAW die of out-of-plane forces on the plate so as to isolate the torque transferred to the plate.
