Piezoelectric Sensing and NDT Testing
Piezoelectric materials can convert mechanical or vibrational forces (e.g. wind, wave, pressure) into an electric current, and vice versa. This phenomenon is very useful for numerous applications including electric generation, sound detection, strain sensor and actuators. Conventional piezoelectric materials are ceramics with anisotropic crystal structures (i.e. lead zirconate titanate), however they have low strain and they are heavy, restricting their applications in sensing and NDT testing for civil infrastructures. Our group focuses on developing polymer based piezoelectric materials and devices for energy harvesting, NDT testing and health monitoring for pavement, building structures and bridges.
