采用多层共烧陶瓷技术制备了氧化物-金属复合材料单片热电发电器。这些器件由Ni0.9Mo0.1和La0.035Sr0.965TiO3作为p型和n型热电材料组成，Y0.03Zr0.97O2用作绝缘体，夹在p型和n型层之间。为了共烧不同的材料，p型层包含20 wt. %的La0.035Sr0.965TiO3;因此，这些是氧化物-金属复合层。所制备的器件有50对p-i-n结，尺寸为5.9mm × 7.0mm × 2.6mm，在ΔT = 360 K时，器件的最大输出功率为450 mW/cm 2。此外，该器件在ΔT = 10 K时产生100 μW的功率，并运行假定为传感器网络系统的射频（RF）发射器电路模块。
Monolithic oxide–metal composite thermoelectric generators (TEGs) were fabricated using multilayer co-fired ceramic technology. These devices consisted of Ni0.9Mo0.1 and La0.035Sr0.965TiO3 as p- and n-type thermoelectric materials, and Y0.03Zr0.97O2 was used as an insulator, sandwiched between p- and n-type layers. To co-fire dissimilar materials, p-type layers contained 20 wt. % La0.035Sr0.965TiO3; thus, these were oxide–metal composite layers. The fabricated device had 50 pairs of p–i–n junctions of 5.9 mm × 7.0 mm × 2.6 mm. The calculated maximum value of the electric power output from the device was 450 mW/cm2 at ΔT = 360 K. Furthermore, this device generated 100 μW at ΔT = 10 K and operated a radio frequency (RF) transmitter circuit module assumed to be a sensor network system.
