Abstract
This paper introduces a new category of electrical current transducers based on piezoelectrets with thermoformed channels exhibiting magnetic characteristics. These magnetic characteristics gave rise to a new class of piezoelectrets called Thermoformed Magneto-Piezoelectrets (MPTs). Testing the MPTs reaction to external electrical currents showed that these devices respond proportionally to the magnetic fields generated by the applied electrical current. The occurrence of the direct piezoelectric effect is thus verified, and when subjected to magnetic fields produced by electrical currents, the sensor evidenced piezoelectric and piezo-magnetic coefficients of 8300 pC/N and 4980pC/G, respectively. Therefore, the additional layer of magnetostrictive material optimized the piezoelectric characteristics of the MPTs, but also allowed them to respond to external magnetic fields produced by electrical currents.
