PROTECTION OF A CHIP OR SYSTEM IN PACKAGE (SIP) USING THE GIANT MAGNETOIMPEDANCE (GMI) EFFECT

摘要

A chip type device (100) or a housing type electronic system comprising at least one protective element (114) from at least a portion of at least one surface (116) of the device, the protective element comprising at least:-An attack detection element (118) of a device having at least one conductive material having a GMI effect, and-The magnetic field transmitter to be borne by the above GMI effect conductive material,Among them, the GMI effect is designed to be realized when the conductive material with the GMI effect passes through the AC excitation current and receives the magnetic field from the magnetic field transmitter (126).
