ABSTRACT:
The invention provides an apparatus for measuring torque of a torque tool by using an indirect structure arranged on one side of the torque tool, in which the apparatus comprises a microstructure part connected with a side surface of the torque tool. The microstructure part further comprises a sensing structure for sensing the strain or displacement generated by a force exerted on the torque tool and converting the strain or displacement into an electrical signal. The electrical signal is then properly calibrated and processed for transforming units by a System-on-Chip (SoC), and converted into the torque value exerted by the user and the value is displayed on a display device.
