Spring constant and damping coefficient of springs built into the LSM6DS3H

[robi]

I am conducting research on robot control, and to handle data obtained from the LSM6DS3H embedded in the robot, I want to understand how acceleration and angular velocity are measured. Specifically, I would like to learn about the internal structure of the accelerometer and gyroscope within the LSM6DS3H. My general understanding is that the structure consists of a mass connected to other parts by springs, and acceleration and angular velocity are measured based on voltage changes due to the compression and extension of these springs. The specific information I am looking for includes the following:

• Diagrams illustrating the connection between the springs and the mass
• Spring constant and damping coefficient
• Mass of the weight
• Natural frequency and damping ratio of the spring-mass system
• Formulas used to calculate acceleration and angular velocity.

Any information on these points would be greatly appreciated.

Hi @robi ,

We can't provide information about the internal structure of our IMUs on ST Community.

However, you can find some answers on the datasheet and looking at the design notes on our website.

Hope this helps.
