US Patent 7709757 Microsystem comprising a deformable bridge

The invention relates to a microsystem comprising a deformable bridge, the ends of which are connected to a substrate. According to the invention, at least one actuation electrode, which is solidly connected to the bridge, is disposed between the center of the bridge and one of the ends next to a counter electrode which is solidly connected to the substrate. The electrodes are intended to deform the deformable bridge such that a lower face of the bridge comes into contact with a contact element formed on the substrate.
