Abstract
A system includes a magnetostrictive strip configured to be wrapped at least partially around an outer surface of a structure. A plurality of coil circuits are disposed on at least one flexible PCB that is configured to be disposed adjacent to the magnetostrictive strip. Each coil circuit is individually controllable by a plurality of channels to at least one of excite or detect guided waves in the structure. A plurality of magnets are configured to induce a magnetic field in the magnetostrictive strip. A connector is configured electrically connect at least one of the plurality of coil circuits and at least one the plurality of channels. A body constructed from a flexible material is sized and configured to at least partially encapsulate at least one other component of the system.
