An experimental study on thermal energy harvesting using Ca0.15(Sr0.5Ba0.5)0.85Nb2O5 pyroelectric ceramics
Abstract Pyroelectric materials can be used for energy harvesting in integrated Micro-Electro-Mechanical-Systems (MEMS) and low power electronics devices. This paper considers the thermal energy harvesting using Ca0.15(Sr0.5Ba0.5)0.85Nb2O5 (CSBN) pyroelectric ceramics. Hot/cold air was used to generate a continuous temporal temperature profile on the material surfaces. The maximum open circuit voltage was observed as 0.26V. The maximum stored energy was 1.9 μJ in 47 μF capacitor (without load resistance). The maximum power was found to be 2.07nW across 3 MΩ and 47 μF.
期刊介绍：
Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals.
Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
