Abstract
Conventional accelerometers are based on test masses that are suspended in some kind of spring damper system. According to an exemplary embodiment of the present invention, a two-dimensional adaptive accelerometer based on dielectrophoresis is provided, which measures an acceleration of a test mass freely floating in a medium by determining the movement of the test mass due to an accelerating force acting on the test mass. A non-uniform electric force field provides for a wide and adjustable dynamic range.
