Publication number: 20230012461Abstract: A magnetoelectric (“ME”) device is disclosed. In one aspect, the ME device includes a first piezoelectric substrate portion and a second piezoelectric substrate portion; a magnetostrictive body with a magnetization oriented in a first direction, the magnetostrictive body arranged on and extending between the first and second portions; a pair of input electrodes arranged on the first portion; and a pair of output electrodes arranged on the second portion. The input electrodes are configured to induce a fringing electric field extending between the input electrodes via the first portion, thereby causing a deformation of the first portion which in turn causes a deformation of the magnetostrictive body such that the magnetization thereof is re-oriented to a second direction due to a reverse magnetostriction. An output voltage is induced between the output electrodes by a deformation of the second portion caused by the re-orientation of the magnetization of the magnetostrictive body.Type: ApplicationFiled: July 8, 2022Publication date: January 12, 2023Inventors: Hanns Christoph ADELMANN, Florin CIUBOTARU
