Abstract

See full text

A method for manufacturing a device having a three-dimensional magnetic structure includes applying or introducing magnetic particles onto or into a carrier element. A plurality of at least partly interconnected cavities are formed between the magnetic particles, which contact one another at points of contact, by coating the arrangement of magnetic particles and the carrier. The cavities are penetrated at least partly by the layer generated when coating, resulting in the three-dimensional magnetic structure. A conductor loop arrangement is provided on the carrier or a further carrier. When a current flows through the conductor loop, an inductance of the conductor loop is changed by the three-dimensional magnetic structure, or a force acts on the three-dimensional magnetic structure or the conductor loop by a magnetic field caused by the current flow, or when the position of the three-dimensional magnetic structure is changed, a current flow is induced through the conductor loop.
