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 Ca-0.15(Sr0.5Ba0.5)(0.85)Nb2O5 (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 J in 47 F capacitor (without load resistance). The maximum power was found to be 2.07nW across 3 M and 47 F.
