Abstract

A pyroelectric coefficient enhanced 2–2 connectivity laminate composites’ energy harvestingcredentials have been assessed. The use of the electrothermal coupling factor for laminate composites(kLam2) for such an assessment has been appraised while the experimental samples are evaluatedto show a significant improvement in their performance via pyroelectric coefficientenhancement, demonstrative of their great potential in energy harvesting applications. Alead zirconate titanate and stainless steel laminate composite with an 88% pyroelectriccoefficient enhancement is shown to increase its maximum power density, efficiency,and electrothermal coupling factor by 254%, while other material pairings havealso been evaluated to exhibit great promise in this application owing to a largepyroelectric coefficient enhancement accompanied by a reduction in total thermal mass.
