Pyroelectricity of PZT-based thick-films

Thermal energy harvesting through pyroelectricity

“…C p in PZT cells were in the range of 30-60 nF. The relative permittivity, ε r , was found in the range 220-260, which is in reasonable agreement with similar thick-film layers [28]. Smaller values of C p were measured for the PVDF cells.…”

Influence of the densification parameters on screen-printed component properties

“…14 In the same way, pyroelectric sensors based on PZT porous layers exhibit higher figures of merit in voltage and current compare to PZT ceramics. 15 Another type of porous thick films application such as lanthanum-strontium cobaltite cathode for zirconia-based solid oxide fuel cells is also very promising. 16 Nevertheless, improvements of the densification process of thick films may be required when firing occurs at temperatures lower than the sintering ones of bulk materials.…”

Pyroelectric properties of BST/PLT composite thick films with addition of xPbO–(1−x)B2O3 glass

“…The porous structure films exhibit lower values for the heat capacitance as well as the thermal conductivity. Although the pyroelectric coefficient is lower than that of the ceramics counterpart, the figure-of-merits result to be higher [9].…”
