Abstract

A torque sensing system generally includes a torque sensor comprising a torque sensing element configured upon a substrate in association with an antenna for sending and receiving wireless signals. A plurality of electronic controlling components for controlling the torque sensor, wherein the electronic controlling components are configured upon another substrate in association with an antenna for sending and receiving the wireless signals to and from the torque sensor, such that the torque sensor is located on a rotating member in order to generate signals indicative of a torque associated with the rotating member, and wherein the signals are wirelessly transmittable from the torque the via the antenna configured upon the substrate in association with the torque sensor.
