dc.description.abstractInhomogeneous strain allows the manifestation of an unexplored component of stress-driven caloric effect (flexocaloric effect) and enhanced pyroelectric performance, obtainable significantly beyond the Curie point. A peak temperature change of 1.5K (at 289K) was predicted from first-principles-based simulations for Ba0.5Sr0.5TiO3 under the application of a strain gradient of 1.5μm-1. Additionally, enhanced pyro-paraelectric coefficient (pyroeelctric coefficient in paraelectric phase) and flexocaloric cooling 11x10-4C.m-2K-1 and 1.02K, respectively, could be obtained (at 330K and 1.5μm-1). A comparative analysis with prevailing literature indicates huge untapped potential and warrants further research.en
