Patent ID: 6840106

Claim:
A sensing structure comprising: a substrate; a movable mass positioned over the substrate and movable laterally with respect to the substrate; a first sensing electrode fixably coupled to the substrate and positioned adjacent to a first portion of the movable mass to form a first capacitive structure for sensing a change in location of the movable mass along a first axis of lateral movement of the movable mass; a second sensing electrode fixably coupled to the substrate and positioned adjacent to a second portion of the movable mass to form a second capacitive structure for sensing a change in location of the movable mass along a second axis of lateral movement of the movable mass, the second axis is generally orthogonal to the first axis; an actuating electrode fixably coupled to the substrate and positioned adjacent to a third portion of the movable mass, wherein a voltage differential between the actuating electrode and the third portion provides a force for lateral movement of the movable mass in a diagonal direction, the diagonal direction being at a first angle with respect to the first axis and at a second angle with respect to the second axis.
