Devices including a substrate and a plurality of coil portions disposed on the substrate. The plurality of coil portions electrically coupled to form a coil structure.

High density coil design and process

A suspension assembly is described. The suspension assembly including a rigid interposer circuit; a plurality of flexible circuits configured to attach to the rigid interposer circuit and movable about an x-axis and a y-axis with respect to the static plate; and a sensor mounting region on the rigid interposer circuit.

Sensor shift structures in optical image stabilization suspensions

A suspension assembly is described. The suspension assembly including a static member or plate; a moving member or plate movable about an x-axis and a y-axis with respect to the static plate; a sensor mounting region on the moving plate; and one or more shape memory alloy (SMA) elements extending between and coupled to the static plate and moving plate. The SMA elements, when driven by a controller, move the moving plate and the sensor mounting region thereon about the x-axis and the y-axis with respect to the static plate.

An apparatus is described. The apparatus may include a substrate and one or more sensors mounted to the substrate. The one or more sensors may be mounted to the substrate using adhesive material and one or more spot welds.

Integrated sensors

SMA actuators and related methods are described. One embodiment of an actuator includes a base; a plurality of buckle arms; and at least a first shape memory alloy wire coupled with a pair of buckle arms of the plurality of buckle arms. Another embodiment of an actuator includes a base and at least one bimorph actuator including a shape memory alloy material. The bimorph actuator attached to the base.

Shape memory alloy actuators and methods thereof

Electric tabs and methods for manufacturing are described. A method includes disposing a dielectric layer on a second side of a base material, the base material having a first side and the second side. The method including developing the dielectric layer on the second side of the base material. And, the method including etching the first side of the base material to form an electrode tab.
