摘要：

A　flexible　printed　meander　coil　(FPMC)-based　magnetostrictive　sensor　(MsS)　which　has　a　central　frequency　around　1.25　MHz　is　presented　in　this　paper.　The　FPMC-based　MsS　can　be　easily　wrapped　onto　the　twisted　strand　surface　and　disassembled　from　the　strand.　It　can　be　also　installed　onto　the　central　rod　of　the　strand　after　being　wrapped　into　multiple　layers.　That　is,　this　FPMC-based　MsS　can　fit　for　the　tested　sample　of　different　diameters.　With　the　proposed　megahertz-range　FPMC-based　MsS,　the　rods/strands　inspection　system　is　potential　to　be　applied　for　practical　inspections,　having　higher　axial　inspection　resolution　and　sensitivity　to　small　defects.　©　2011　IEEE.
