Abstract
Piezoelectric materials have been extensively studied in recent years for the development of electromechanical harvesting devices; however, much of the research that is available in open literature focuses on increasing mechanical and electrical performance, increasing efficiency, consequently harvesting. The conversion of mechanical energy to electric energy is provided by the electromechanical coupling between flexible structure and piezoceramic element. There are basically two types of strategies adopted when integrating piezoelectric sensors and actuators into flexible structures: bonding to the host structure surfaces or incorporation into a laminated structure of thin patches or layers of piezoelectric ceramics. In both cases, the interface between the host structure and the piezoelectric device plays a decisive role in terms of mechanical stress and voltage transfer mechanisms. This work presents a study on the influence of parametric uncertainties on the thickness properties and Young's modulus of adhesive bond strength, based on the expected statistical properties of variables, such as expected nominal value, dispersion and positivity.
