Dear friends,

I am modelling an optical based underwater acoustic sensor to detect the acoustic sound wave which is induced inside the water-filled tank using COMSOL Multiphysics software. Due to the acoustic waves strike to the sensor there is deformation on it. My question is how to calculate the sensitivity of the sensor.

For understanding the question, please find the below attached fig.

I would be grateful if somebody guides me in this regard.

Thanks & Regards
