A feasibility study on using polymer fiber Bragg sensors (PFBG) for providing force feedback to minimally invasive
surgical devices is carried out. For this purpose a 3 mm long PFBG is fabricated and characterized for strain and
temperature sensitivities. The PFBG sensor is then integrated onto a commercial laparoscopic clip applicator which is
used as a proof of concept device. The force characterization of the clip applicator is carried out, with a replica setup
which simulates the clip forming process of the device. An original clip is then formed without and with synthetic tissue
samples of different hardness. The replica device force profile and original clip forming force profile follows the same
pattern and thus the calibration data can be used to calculate the original force exerting on the tissues which can help in
optimizing the clip formation process or can be used for providing force feedback capability to the device.
