本文建立了开路条件下的热释电（PY）效应的解析模型和各种PY与非热释电（NP）/弹性材料对的2-2连接层合板。从我们的分析中可以明显看出，在短路和开路条件下，各种PY-NP对的PY系数和效率优值之间确实存在很大的差异。我们认为，这意味着应该有一个更大的区别，这两个电气条件下的PY系数比以前认为的。各种PY-NP材料对，可以用来确定其在开路条件下的PY系数增强潜力的指标已被确定。研究的PY材料是锆钛酸铅（PZT-5 H和PZT-5A），钛酸钡，钽酸锂，钛酸锂和聚偏氟乙烯（PVDF），而NP材料是不锈钢，聚四氟乙烯（PTFE或Teflon），氯化...
An analytical model for the pyroelectric (PY) effect under open circuit condition and 2-2 connectivity laminates of various pairs of PY and nonpyroelectric (NP)/elastic materials has been developed. It is evident from our analysis that there indeed is a substantial dissimilarity between the PY coefficients and figure of merit for efficiency for various PY-NP pairs under short circuit and open circuit conditions. We believe this implies that there should be a greater distinction made between the PY coefficients under these two electrical conditions than previously thought. The indicators for various PY-NP material pairs that can be utilized to determine their PY coefficient enhancement potential under open circuit condition have been identified. The investigated PY materials are lead zirconate titanate (PZT-5H and PZT-5A), barium titanate, lithium tantalate, lithium niobate, and polyvinylidene fluoride (PVDF), while the NP materials are stainless steel, polytetrafluoroethylene (PTFE or Teflon), chlorinated...
