Flexible coil arrangement for a magnetoelectric displacement sensor, displacement sensor and manufacturing method

摘要

A coil assembly according to the present invention comprises an electrically insulating, at least partially flexible support (202) having a first surface (230) and a second surface (232) and at least one through opening (210) extending between the first and second Surface extends. At least one first conductive line (204) is disposed on the first surface (230), and at least one second conductive line (206) is disposed on the second surface (232), the first and second conductive lines electrically interconnecting via at least one via (208) are connected to form at least a first coil winding. A magnetic core member (212, 218) is mechanically connected to the flexible support and extends through the opening (210) such that at least a first portion of the core member engages an outer surface of the flexible support adjacent the first surface and at least a second Part of the core element with one of the second surface adjacent outer surface of the flexible support in abutment.
