Piezoelectric sensors and actuators are used in various applications. They have electromechanical properties. Electric voltage is generated when strain is applied on them and vice versa. These patches can be used at cryogenic temperatures as well as elevated temperatures according to different applications. Piezoelectric patches are pasted on the surface of the structure to sense the vibrations. Different adhesives can be used to paste piezoelectric patches on the structure. In this paper, two different Adhesives, Araldite and Cyanoacrylate are used to paste piezoelectric patches. Two test set up are prepared using two different adhesives. Sensor voltage is obtained from piezoelectric patches at reference temperature and at elevated temperatures. Results are obtained, compared and analyzed. Performance of adhesives is compared at reference temperature and at elevated temperature. Where, Cyanoacrylate is found to be better adhesive to paste piezoelectric patches on the surface of structure as compared to Araldite adhesive.
