N2 - Brain puncture procedures generate complex lateral forces that, if excessive, can damage healthy tissue and deviate the needle from its intended path, increasing surgical risk. Traditional metallic force sensors are unsuitable for MRI environments due to their size and electromagnetic interference. To overcome these limitations, this study presents a fiber Bragg grating (FBG)-based lateral force sensing system integrated into a piezoelectric-driven brain puncture device, enabling real-time force monitoring under MRI conditions. Three FBG sensors are arranged at 120° intervals around the needle shaft, forming a compact, MRI-compatible sensing structure. A mechanical calibration model with temperature decoupling was established to ensure accurate measurements. Simulation and experimental results show a lateral force sensitivity of 990 pm/N in the 0-1 N range, with measurement error below 4.5% full scale (FS), and reliable operation in strong magnetic fields. This work offers a high-sensitivity, electromagnetically immune solution for force sensing in minimally invasive neurosurgery, providing technical support for safer and more precise MRI-guided brain puncture procedures.
