A rotating power tool is provided. The rotating power tool may include a bevel gear set having a bevel gear and a conductive spiral disposed on the bevel gear. The conductive spiral may be configured to, in response to the bevel gear deforming due to a torque being applied to the bevel gear, change a resistance of the conductive spiral. The rotating power tool may further include an antenna electrically connected to the conductive spiral. The antenna may be configured to emit an output signal at a frequency that is based on the resistance value of the conductive spiral. The frequency of the output signal may be indicative of an amount of torque being applied to the bevel gear.

A torque measurement system includes a first rotatable carrier structure mechanically coupled to a rotational shaft; a second rotatable carrier structure mechanically coupled to the rotational shaft; a first mutually coupled structure including a first track mechanically coupled to the first rotatable carrier structure and a second track mechanically coupled to the second rotatable carrier structure, where the first track and the second track are coupled together by a first torque dependent coupling; a second mutually coupled structure including a third track mechanically coupled to the first rotatable carrier structure and a fourth track mechanically coupled to the second rotatable carrier structure, where the third track and the fourth track are coupled together by a second torque dependent coupling. In response to a rotation of the rotational shaft, the first torque dependent coupling is configured to increase and the second torque dependent coupling is configured to decrease.
