Abstract: The present invention relates to a strain gauge having a conductive fluid made of a glycerin/aqueous salt mixture, and methods of making the strain gauge. The strain gauge comprises a polymer sleeve; a fluid piezoresistive material made by the glycerin/aqueous salt mixture; a metal tube, a metal conductive pad or a conductive polymer pad arranged on both ends of the polymer sleeve, wherein the fluid piezoresistive material is included in the polymer sleeve. According to the invention, the strain gauge is capable of measuring large displacement of around 30% true strain.
本发明涉及一种具有由甘油/水盐混合物制成的传导流体的应变体以及一种制造这种应变计的方法,所述应变计包括:聚合体套管;由甘油/水盐混合物制成的流体压阻材料;设置在所述聚合体套管两端的金属管、金属传导垫或传导聚合体垫;其中所述流体压阻材料包含在所述聚合体套管之中。根据本发明,所述应变计能测量30%左右实际应变的大位移。
