In-Vivo Tissue Identification on Mice Using a Fiber Optical Tip Force Sensing Needle

This paper presents in-vivo tissue identification on mice by our recently developed novel fiber optical tip force sensing needle. The needle can directly measure the axial force required to penetrate a tissue at its tip, which can then be used for in-vivo identification of tissues. Both ex-vivo and in-vivo tissue experiments were carried out on 32 mice. Ex-vivo tissue insertions were conducted on ...
