Abstract:
The invention relates to a method for producing a device (120) having a three-dimensional magnetic structure (132), comprising a step of applying magnetic particles (130) onto or into a carrier element (122), wherein a plurality of hollow spaces that are at least partially connected to one another are formed between the magnetic particles, and wherein the magnetic particles are brought into contact with one another at contact points. The method also comprises a step of joining the magnetic particle at the contact points by coating the assembly formed by magnetic particles and the carrier element, wherein the hollow spaces are penetrated at least partially by the layer generated by the coating. The device comprises a conductor loop assembly (124) on the carrier element or a further carrier element, such that in the event of a current flow through the conductor loop assembly (1), an inductivity of the conductor loop assembly is altered by the three-dimensional magnetic structure, or (2) a force acts on the three-dimensional magnetic structure or the conductor loop assembly via a magnetic field generated by the current flow, or (3) in the event of a change of position of the three-dimensional magnetic structure, a current flow is induced via the conductor loop assembly.
Abstract:
A mechanical device includes a long, narrow element made of a rigid, elastic material. A rigid frame is configured to anchor at least one end of the element, which is attached to the frame, and to define a gap running longitudinally along the element between the beam and the frame, so that the element is free to move within the gap. A solid filler material, different from the rigid, elastic material, fills at least a part of the gap between the element and the frame so as to permit a first mode of movement of the element within the gap while inhibiting a different, second mode of movement.
Abstract:
The invention relates to a flat coil and to a lithographic method for producing microcomponents with metal component structures in the sub-millimeter range. According to the inventive method, a resist material is structured by means of selective exposition and removing the unexposed zones and filling in the gaps between the resist structures with metal by means of a galvanic method to produce the metal component structures. The aim of the invention is to improve such a method so that the microcomponents can be subdivided during said process. To this end, a structured three-dimensional sacrificial metal layer is produced during the production of the microcomponent, said sacrificial layer delimiting the microcomponent and being removed once the microcomponent is due to be subdivided. The invention also relates to a method for producing microcomponents with component structures of cross-linkable resist material and to a flat coil for micromotors with at least one coil layer with strip conductors in the sub-millimeter range.
Abstract:
A platform includes first and second actuation layers. The first actuation layer includes first and second frames and a plurality of actuators connected between the first frame and the second frame, wherein the plurality of actuators are adapted to move the first and second frames with respect to each other in a first direction. The second actuation layer includes third and fourth frames and a plurality of actuators connected between the third frame and the fourth frame, wherein the plurality of actuators are adapted to move the third frame and the fourth frame with respect to each other in a second direction, different from the first direction. Thereby, the fourth frame of the second actuation layer and the second frame of the first actuation layer are mechanically connected to each other, such that the second actuation layer experiences the movement in the first direction induced by the first actuation layer.
Abstract:
Miniature camera modules that achieve autofocus (AF) and optical image stabilization (OIS) using piston-tube electrostatic actuators are disclosed. Various embodiments of the camera modules that work on two main mechanisms are disclosed. The two mechanisms are the whole barrel motion leading to AF and OIS and the single lens motion leading to AF. The MEMS actuator is integrated within a housing which is, in turn, coupled with an image sensor module. Autofocus is achieved by a translational motion of the piston-tube electrostatic actuator to translate the whole barrel back and forth. OIS is achieved by tilting the whole barrel using the tilting action of the piston-tube actuator.
