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.
