ABSTRACT:
Torque sensing methods and systems are disclosed. In general, a sensing element and a sensor housing can be provided for maintaining the sensing element. A plurality of wirebond posts can be assembled perpendicular to a plane of the sensing element. The sensing element can then be wire bonded to the plurality of wirebond posts, such that the sensing element, the sensor housing and the plurality of wirebond posts form a sensor housing assembly thereof for torque sensing applications thereof. The sensor housing assembly is then connected to a shaft to form a hermetic seal thereof. The sensor housing assembly can also be electrically attached to an antenna for wirelessly communicating data to and from the sensing element. The sensing element can be configured, for example, as a surface acoustic wave (SAW) sensing component.
