Monolithic oxide-metal composite thermoelectric generators were fabricated using multilayer co-fired ceramics technology. These devices consisted of Ni_<0.9>Mo_<0.1> and La_<0.035>Sr_<0.965>TiO3 as p- and n-type thermoelectric materials, and Y_<0.03>Zr_<0.97>O_2 was used as an insulator, sandwiched between p- and n-type layers. To co-fire dissimilar materials, p-type layers contained 20wt% La_<0.035>Sr_<0.965>TiO_3; thus, these were oxide-metal composite layers. The fabricated device had 50 pairs of p-i-n junctions of 5.9mm×7.0mm×2.6mm. The calculated maximum value of the electric power output from the device was 100μW at ΔT=10K and operated a radio frequency (RF) transmitter circuit module assumed to be a sensor network system.
