Title: Andre Piorra: Innovator in Magnetoelectric Technology
Introduction
Andre Piorra is a notable inventor based in Kiel, Germany. She has made significant contributions to the field of magnetoelectric technology, holding two patents that showcase her innovative approach to magnetic field measurement.
Latest Patents
Her latest patents include a method for magnetoelectric magnetic field measurement with frequency conversion. This method utilizes a magnetoelectric composite element as an oscillator, where a time-dependent measurement magnetic field influences the magnetostrictive phase of the composite element. An electrical measurement voltage is extracted across the piezoelectric phase, which is then used to infer the measurement magnetic field. Additionally, at least one dielectric phase is bonded to the magnetostrictive phase, exhibiting a change in length when an electrical voltage is applied. This change is non-linear and is modulated periodically by an electrical voltage.
Another significant patent is for a magnetoelectric sensor and its production method. These sensors can be manufactured using established thin film technology and produce a magnetoelectric voltage that is significantly higher for a predetermined magnetic field compared to traditional cantilever-beam sensors. The design features a thick dielectric layer positioned between the ferroelectric and magnetostrictive phases, with an electrode arrangement designed to tap the magnetoelectric voltage along the layer's extent. This innovative design allows for easy manufacturing by coating conventional dielectric substrates with functional layers.
