Abstract
Provided is a torque wrench, or Mechanical Torque Limiting Device (MTLD), that is configured to accurately indicate the torque applied thereby on the object (or vice versa). The measurement of the torque is carried out by incorporating a pressure sensitive material in a gripping portion that is associated with the body of the torque wrench. The pressure sensitive material is configured to exhibit a signal upon application of force thereof. The signal can be an electric-based, color-based, motion-based (vibrations) or audio-based indication.

A torque wrench comprising:
- an elongated handle body extending between a proximal end and a distal end;
- a wrench head unit disposed at the distal end;
- at least one pressure sensing unit associated with the elongated body and configured with at least one user interface gripping portion, each of the gripping portions comprises a pressure sensitive material configured to exhibit a signal upon application of a certain pressure thereon, wherein said signal is indicative of torque applied to the wrench head unit;
- wherein said pressure sensitive material is piezochromic material.
