建立了确定热释电系数（PY coef.）通过二次热电效应的增强，利用热电锆钛酸铅（PZT）和弹性层压层的2-2连接性。基于这一分析的预测，层状不锈钢（St）PZT/St结构已被制造和超过100%的PY系数增强。在这些结构中观察到。通过考虑St和PZT界面处的应变传递损失，获得了理论和实验结果之间的良好一致性。
A mathematical model has been developed to determine the pyroelectric coefficient (PY coef.) enhancement through secondary pyroelectric effect, utilizing a 2-2 connectivity of the pyroelectric lead zirconate titanate (PZT) and elastic laminate layers. Based on the prediction of this analysis, laminar stainless steel (St) PZT/St structures have been fabricated and more than 100% enhancement in PY coef. has been observed in these structures. Good agreement between the theoretical and experimental results was obtained by taking into account of the stain transfer loss at the St and PZT interface.
