Abstract
Flexoelectric effect is acquiring increased attention owing to its potential advantages towards sensor/transducer applications. Flexoelectricity can be employed to raise the functional working temperature of most ferroelectric devices beyond Curie temperature. Few recent studies have claimed significant (flexoelectric) piezoelectric performance above Curie temperature. However, little effort has been made to develop the pyroelectric capabilities of such materials. This paper aims to highlight the pyro-paraelectric (pyroelectric above Curie temperature) attributes of multiple ferroelectric systems, under the influence of inhomogeneous strain. Furthermore, cantilever shaped system is optimised for enhanced pyroelectric performance to generate a large output signal, in a wide temperature range.
