mechanical pressure on the sensor affects the calibration of the accelerometer

Well, I’m currently using an icm-20948 with a house calibration to improve sensor performance (accelerometer) and it works very well. On the other hand, we notice that it is affected when one presses on the sensor. A simple mechanical pressure on the sensor affects the calibration of the accelerometer. The sensor serves to do the motion analysis and must be inserted between the feet and the shoe so it is affected by the pressure. We tried to use the epoxy to reduce the impact of mechanical pressure on the accelerometer. We have a decrease but it is not enough. I would like to know if you have ever encountered this kind of problem. If so is that you can help us in encapsulation or other method to lessen the impact.
