Original Abstract Submitted

A microelectromechanical accelerometer is provided that includes one or more proof masses. The accelerometer also includes four sets of stator combs that form a set of four measurement capacitors together with rotor combs. Some rotor combs have a positive offset in a direction in the device plane in relation to stator, while others have a negative offset. Some rotor combs have a negative offset in a direction perpendicular to the device plane in relation to stator combs. Moreover, some stator combs have a negative offset in the direction perpendicular to the device plane in relation to rotor combs.
