Abstract
Methods and devices related to current sensing are provided. Magnetoresistive sensor elements are provided on opposite sides of a conductor.
Claims22
A method comprising:
- providing a plurality of magnetoresistive sensor elements on opposite sides of an electrical conductor;
- and
- providing the plurality of magnetoresistive sensor elements on a flexible printed circuit board,
- wherein the electrical conductor is provided on a subset of the plurality of magnetoresistive sensor elements, and
- wherein providing the plurality of magnetoresistive sensor elements on the opposite sides of the electrical conductor comprises folding the flexible printed circuit board around the electrical conductor.
2 more elements
A device, comprising:
- an electrical conductor;
- a flexible printed circuit board at least partly surrounding the electrical conductor;
- a first housing provided on the flexible printed circuit board, the first housing comprising a first magnetoresistive sensor element and a first resistive element, wherein the first housing is provided on a first side of the electrical conductor;
