Enhancing power output of magnetoelectric films in miniature device enclosures

An apparatus of a magnetoelectric film comprising:

• an enclosure;
• a plurality of magnetoelectric (ME) minifilms arranged along an inner perimeter of the enclosure with a spacing in between adjacent ME minifilms of the plurality of ME minifilms, positioned such that a plane of the ME minifilms is parallel to a plane of the enclosure, and wherein the ME minifilms are comprised of:
• at least one layer of magnetostrictive material with a thickness configured to be magnetized inducing a mechanical strain when an external magnetic field that is generated by a transmitter coil, is applied;
• and
• at least one layer of piezoelectric material on the at least one layer of magnetostrictive material configured to generate an electrical signal in response to the mechanical strain from the at least one layer of magnetostrictive material.

An apparatus comprising:

• an enclosure having a lid to cover one end of the enclosure along a longitudinal axis;
• a magnetoelectric film that is embedded in the lid along surface of the lid such that the magnetoelectric film is perpendicular to the longitudinal axis of the enclosure, wherein the magnetoelectric film comprises:
• at least one layer of magnetostrictive material configured to be magnetized inducing a mechanical strain when an external magnetic field, is applied;
• and
• at least one layer of piezoelectric material on the at least one layer of magnetostrictive element configured to generate an electrical signal in response to the mechanical strain from the at least one layer of magnetostrictive material;
• and
• a plurality of coils positioned above the enclosure, configured to generate the external magnetic field in a direction perpendicular to an orientation of the ME film.
