  • Patent number: 10688469
    Abstract: The invention relates to a porous hydrogel matrix having substantially interconnected tunnel-shaped micropores with a three-dimensional configuration of an interconnected hollow tetrapod network. Such matrices may be used to entrap motile cells that migrate into the micropores of said matrix. The matrices of the invention are formed by a method comprising the steps of providing a solution of a hydrogel-forming material, providing a template material with a three-dimensional configuration corresponding to the negative configuration of the desired interconnected porous structure of the hydrogel material, said template material comprising interconnected zinc oxide tetrapod (t-ZnO) networks, casting the solution of hydrogel-forming material onto the template and removing the template material from the hydrogel material by acid hydrolysis of the template material.

  • Patent number: 10628927
    Abstract: A computer-aided image correction method for images with at least spatially partially coherent light requiring only a phase-modulated image as input. It does not reconstruct the phases on the image sensor, but rather assumes that they should ideally all be the same. With this assumption, the invention formulates a constraint and an update rule. The result of the iteration is an amplitude distribution of the lightwave field, which could have been measured directly if aberrations in the form of wavefront distortions had not contributed to the actual image acquisition. Further, a device that can, using the image correction method, be used as an adaptive optic for imaging instruments.

  • Patent number: 10613159
    Abstract: A magnetic field measuring method using a magnetoelectric composite element as an oscillator, in which a time-dependent measurement magnetic field acts on the magnetostrictive phase of the composite element, and an electrical measurement voltage is tapped off across the piezoelectric phase of the composite element and is used to infer the measurement magnetic field. At least one dielectric phase is connected to the magnetostrictive phase of the composite element by a material bond. When an electrical voltage is applied, the dielectric phase exhibits a change in length, the magnitude of which depends in a non-linear manner on the magnitude of the voltage, and a temporally periodic electrical modulation voltage is applied to the dielectric phase.

  • Patent number: 9841472
    Abstract: Magnetoelectric sensors that can be manufactured using known methods of thin film technology and output an ME voltage that is many times higher for a predetermined magnetic field than the known cantilever-beam sensor. The design that is termed separator ME sensor is characterized by the arrangement of a thick dielectric layer (14) between the ferroelectric (10) and the magnetostrictive phases (12), and by an electrode arrangement (18) applied on one side of the ferroelectric (10) and that is engineered to tap the ME voltage along the extent of the layer. Advantageously, it can be manufactured easily by coating conventional dielectric substrates (14) on the front and rear with one each of the functional layers (10, 12).
