Jia, Y. (author), Or, S.W. (author), Chan, H.L.W. (author), Jiao, J. (author), Luo, H. (author), Van der Zwaag, S. (author)We report a power supply-free, bidirectional electric current-voltage converter based on a coil-wound laminated composite of magnetostrictive alloy and piezoelectric crystal. An electric current applied to the coil induces a magnetic field, resulting in an electric voltage from the composite due to the direct magnetoelectric effect. Conversely,...journal article 2009
