In this work, we propose the use of a magnetic damper in the FBG-based cantilever accelerometer (FCA) to reduce the distortion of signal due to the infinite signal amplification at the resonant frequency. The magnetic damper comprises a permanent magnet and a U-shape aluminum structure. The permanen...
