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