Abstract
A rolled-up electromagnetic component for on-chip applications comprises: a multilayer sheet in a rolled configuration comprising at least one turn about a longitudinal axis; a core defined by a first turn of the rolled configuration; and a soft magnetic material disposed within the core, where the multilayer sheet comprises a conductive pattern layer on a strain-relieved layer. A method of making a rolled-up electromagnetic component for on-chip applications includes forming a rolled-up device comprising: a multilayer sheet in a rolled configuration having at least one turn about a longitudinal axis, where the multilayer sheet comprises a conductive pattern layer on a strain-relieved layer; and a core defined by a first turn of the rolled configuration. The method further includes introducing a soft magnetic material into the core.
