In laparoscopic surgery, surgeons do not feel accurate force applied to surgical devices. Therefore, development of force sensors for surgical devices is highly required. In this paper, we propose a non-contact whistle sensor together with a method of thermal compensation. The principle of the non-contact whistle sensor is based on the change in frequency when the distance between the air plenum and the slider is varied, which plays the role of air resistance while keeping non-contact. This sensor removes the problems with friction and loading on surgical devices which the previous contact-type whistle sensor has. The non-contact whistle sensor can measure vertical and axial displacements within error of 2 percent of the measuring range.
