外文摘要：In this paper, a cement-based magnetoelectric (ME) laminated composite is fabricated by bonding the piezoelectric material lead zirconate titanate (PZT) between two C-M layers made of the mixture of cement and magnetostrictive material to form a sandwich structure. As well known, inherent measurement errors of traditional electric sensors are definitely induced by magnetic interference in magnetic field. Thus, it is impossible to measure the magnetostrictive strain due to a variable magnetic field. In this paper, the fiber Bragg grating (FBG) sensors were used instead of the traditional strain gauges to measure the strain of the cement-based magnetostrictive layers in a variable bias magnetic field. It can be concluded that the FBG sensors is a reliable choice as its tiny size, high sensitivity and immunity to magnetic interference. (C) 2017 Elsevier Ltd. All rights reserved.
