The folded springs are symmetrically disposed about the axis. Each folded spring has a moving end and a fixed end, the moving end is connected to the rotary element, and the fixed end is connected to the at least one restraint. The moving end is not located on the axis, and the fixed end is not located on the axis. A moving distance is defined as a distance between the moving end and the axis, a fixed distance is defined as a distance between the fixed end and the axis. A spring length is defined as a distance between the moving end and the fixed end. The spring length is varied according to the rotation of the rotary element.

Abstract: A microelectromechanical gyroscope structure for detecting angular motion about an axis of angular motion. A drive element is suspended for one-dimensional motion in a direction of a drive axis, and a sense body carries one or more sense rotor electrodes and is coupled to the drive element with a first directional spring structure that forces the sense body to move with the drive element and has a preferred direction of motion in a direction of a sense axis. The drive element includes an actuation body and a drive frame wherein the first spring structure couples the sense body directionally to the drive frame, and a second directional spring structure that couples the drive frame to the actuation body and has a preferred direction of motion in the direction of the sense axis.

Abstract: A method of making a micro electromechanical system (MEMS) package includes patterning a substrate to form a MEMS section. The method further includes bonding a carrier to a surface of the substrate. The carrier is free of active devices. The carrier includes a carrier bond pad on a surface of the carrier opposite the MEMS section. The carrier bond pad is electrically connected to the MEMS section. The method further includes bonding a wafer bond pad of an active circuit wafer to the carrier bond pad. The bonding of the wafer bond pad to the carrier bond pad includes re-graining the wafer bond pad to form at least one grain boundary extending from the wafer bond pad to the carrier bond pad.

Abstract: A MEMS apparatus with dynamic displacement control includes a MEMS parallel plate capacitor integrated with one or more memristors in a series configuration wherein a displacement is observable as a function of memristance, such that an upper electrode position is capable of being interpreted in a form of a resistance rather than a capacitance. The current is limited by said MEMS parallel plate capacitor restricting a change in the resistance of the memristor(s). The memristor(s) can be employed in some embodiments a sensor element to improve a MEMS operation range.

Abstract: A MEMS structure includes a planar substrate, a support body coupled to the planar substrate, a fixed electrode coupled to the planar substrate and a moveable portion. The movable portion is spaced from and faces the fixed electrode. The movable electrode includes a movable weight and an intermediate frame surrounding an outer edge of the movable weight. A plurality of elastic supports connect the movable weight to the intermediate frame. The elastic supports are elastically deformable in a first direction extending parallel to the plane of the substrate such that the movable weight can move in the first direction. At least one torsion bar pivotally connects one end of the intermediate frame to the support body so as to allow the intermediate frame, and with it the movable weight, to pivot around an axis which extends parallel to the plane of the substrate and perpendicular to the first direction.
