Volume 19 number 12, december 2010 a larger tip displacement (400 µm) than silicon-based actuators (1404 µm) when both of the films were driven by 10 v at the . These behaviors caused appreciable magnetoelectric responses based on magnetic-mechanical-electric coupling our results indicated that the thickness of the pb(zr052ti048)o3 film was important in obtaining strong magnetoelectric coupling. This paper studies the application of laminate magnetoelectric (me) material in displacement sensor we studied the l-l block composite thanks to designed structure by coupling displacement signal with the displacement potential of me composite.
A passive alternating current sensor for sensing a current-carrying conductor is disclosed the passive alternating current sensor includes a substrate, a magnetic body, at least one coil and a first measuring circuit. Based on the distributed parameter model, the transverse displacement of a one-side fixed beam with a tip mass can be represented by an absolutely and uniformly convergent series of the eigenfunctions as 34,35 34 d. Recent demonstrations of composite structures based upon piezoelectric – magnetic metallic alloy materials have shown the ability to generate significant power density under applied mechanical and magnetic fields , for example - self-biased magnetoelectric coefficients on the order of 3 v/cm e has been obtained from the piezoelectric films .
