Sensor Incorporating Multiferroic Materials For Detecting Both Electric and Magnetic Fields

摘要

A sensor for detecting both magnetic fields and electric fields can include at least one Sawyer-Tower (ST) circuit that can incorporate a multiferroic capacitor. An odd number of ST circuits coupled together in a ring configuration, so that for each ST circuit, the output of one ST circuit is an input to another of the ST circuits. The multiferroic capacitors can include a multiferroic layer that can be deposed on a substrate. For each multiferroic capacitor, the deposition process can cause an inherent amount of impurities in the multiferroic layer. The number of said odd number of ST circuits to be coupled together is chosen according to the amount of impurities, to “forgive” the impurities. The higher the level of impurities in the multiferroic layers, that more ST circuits that are required in the ring to achieve the same sensor sensitivity. BDFO can be chosen for the multiferroic material.
