Force feedback plays a very important role in medical surgery. In minimally invasive surgery (MIS), however, long and stiff bars of surgical instruments diminish force-feedback to the surgeon. In the case of minimally invasive robotic surgery (MIRS), force-feedback is totally eliminated. Previous researchers have reported that the absence of force-feedback increased the average force magnitude applied...
This paper describes two kinds of the tactile sensors using the optical fiber sensors. One is the tactile sensor using fiber Bragg grating (FBG) sensor. Bragg grating inscribed in an optical fiber causes reflect of a spectral component at the Bragg wavelength. This sensor can detect external force using change of the reflective wavelength. The other is the tactile sensor using the microbending optical...
