This paper presents the principle, structure and performance of a newly developed MR-compatible force sensor. It employs a new optical micrometry that enables highly accurate and highly sensitive displacement measurement. The sensor accuracy is better than 1.0 %, and the maximum displacement of the detector is about 10 μm for a range of the applied force from 0 to 6 N.
