| Abstract: | Using the converse piezoelectric effect , the sensing properties of integrating fiber grating with pizoelectric material for voltage sensing head under low frequence or direct supply conditions are analyzed in this pepar ,the relational expression of Bragg reflected wavelength λ B against detected voltage U is obtained uniting PZT-5H and SbSI two piezoelectrical materials with fiber grating,among U, Δ λ B ,λ B , Δ L/L four parameters for calculated curves are also given , and that is correlated with brief discussion. |
