Microfluidic array, method of manufacture, measuring system comprising the microfluidic array, and use

A variable-stiffness module includes a rigid structure having a first stiffness, an intermediate substrate having a second stiffness less than the first stiffness, and a flexible substrate having a third stiffness less than the second stiffness. The rigid structure is disposed on the intermediate substrate and the intermediate substrate is disposed on the flexible substrate. A conductor is disposed partially on the intermediate substrate and partially on the flexible substrate and is connected to the rigid structure. The conductor extends from the rigid structure to the intermediate substrate to the flexible substrate. In some embodiments, a variable-stiffness module includes any combination of multiple rigid structures, multiple intermediate substrates, and multiple conductors. The conductor can be an optical conductor or an electrical conductor and can be disposed over the rigid structure or between the rigid structure and the intermediate substrate.

Variable stiffness modules

A method for producing a security element () and a security element () in the form of a multilayered film body having a top side facing the observer. The security element () has a volume hologram layer, in which a volume hologram is recorded, which provides a first optically variable information item. The security element () has a replication layer, in the surface of which a relief structure providing a second optically variable information item is molded and which is arranged above the volume hologram layer. A partial metallic layer is arranged between the volume hologram layer and the replication layer, wherein the metallic layer is provided in one or a plurality of first zones of the security element and the metallic layer is not provided in one or a plurality of second zones of the security element.

Security element and method for producing a security element

The invention concerns a security element () having a top side and an underside and a process for the production thereof. The security element has a transparent layer () with a non-homogenous refractive index, in which a plurality of Bragg planes are formed by a refractive index variation. The transparent layer () is of a layer thickness of between 5 &#x3bc;m and 200 &#x3bc;m and the transparent layer () has a plurality of first zones () of a smallest dimension of less than 300 &#x3bc;m, which are arranged in accordance with a first grid raster in a one-dimensional or two-dimensional succession in mutually adjacent relationship and in which the Bragg planes of the transparent layer are respectively shaped to provide a respective transmissive optical imaging function.

Security element and process for the production of a security element

The invention concerns a security element in the form of a multi-layer film body having a volume hologram layer with two different items of optical information and a process for the production of such a security element.
