Thermal-electrical energy converters based on pyroelectric effect were investigated for energy harvesting and possible use in ultralow-power sensor modules. Thermal energy harvesting using pyroelectric effects in PZT-based ceramics with different Tc, PVDF films, and PMN-PT crystals were investigated. With decreasing Curie temperature (Tc) of the PZT-based ceramics, the output voltage due to pyroelectric effects increased. The output power and power density of PZT ceramics with Tc of 145°C were 5.2μW and 1.66 μW/cm2 under 5 K/s temperature change, respectively. PLZT ceramics withTc of 140°C exhibited large energy generation of 54.8 J/L/cycle with temperature variations from 30°C to 200°C and field variations from 0 to 20kV/cm. Ba(Zr0.2Ti0.8)O3 ceramics withTc of 40°C exhibited energy generation of 58.6 J/L/cycle with temperature variations from30°C to 125°C and field variations from 0 to 20kV/cm.

研究了基于热释电效应的热电能量转换器用于能量收集和在超低功耗传感器模块中的可能应用。研究了不同Tc PZT基陶瓷、PVDF薄膜和PMN-PT晶体的热释电效应。随着PZT基陶瓷居里温度（Tc）的降低，热释电效应产生的输出电压增加。在5 K/s的温度变化下，Tc为145°C的PZT陶瓷的输出功率和功率密度分别为5.2μW和1.66 μW/cm 2。当温度变化范围为30°C ~ 200°C，电场变化范围为0 ~ 20 kV/cm时，Tc为140°C的PLZT陶瓷具有54.8J/L/cycle的大能量产生。Tc为40°C的Ba（Zr0.2Ti0.8）O3陶瓷在30 °C ~ 125°C的温度范围内和0 ~ 20 kV/cm的电场变化范围内的能量输出为58.6J/L/cycle。
