Damped linear accerelometer

A linear accelerometer comprising:

• a fixed part,
• a rotationally moving part in a plane of the accelerometer around an axis of rotation orthogonal to the plane of the accelerometer, the moving part comprising a center of gravity distinct from a point of intersection of the axis of rotation and the plane of the accelerometer,
• suspension means between the moving part and the fixed part, forming a pivot link between the moving part and the fixed part and limiting translational displacements of the moving part with respect to the fixed part,
• a detector for detecting the displacement of the moving part with respect to the fixed part,
• viscous damping means for damping the displacement of the moving part in said plane, said viscous damping means comprising interdigitated combs, at least one first comb on the moving part and at least one second comb on the fixed part, the first comb and the second comb being interdigitated and the first comb and the second comb being at the same electric potential.
