The needs of force measurement are getting stronger in advanced medical technologies for realizing advanced treatments and precise assessments. In this paper, a tube shape force sensor using optical fiber is presented. The sensor realizes a precise 3-DOF force measurement using multiple optical fibers. A preliminary test revealed that the sensor has a linear characteristic according to the load. In addition, we conducted frequency analysis of the sensor output which is observed in temperature changing environment. As a result, the sensor also realizes a thermal compensation applying High-pass filter based on frequency analysis.
