Abstract

A mixture of glycerin with salt water is proposed as a mean for piezoresistive strain measurement. Electrochemical impedance spectroscopy (EIS) is conducted for the investigation of the electrical conductive behavior of the mixture confined within a definite volume. The role of glycerin is to increase the viscosity of the mixture, to reduce water loss due to evaporation and to lower the rate of corrosion on the electrode. The applied strain has caused an increase in both the resistance to charge transfer (Ret) and the resistance of the salt solution which is reflected in an increase in the resistance of the system (Rsys). A linear relationship between Z re and ε in the strain range up to about 30 % is verified. The use of ionic liquids for green chemistry has been suggested for years and its use as an electrical conductive media in strain gauge technology is found to be environmentally friendly.
