“…Multilayer‐textured Pb(Mg 1/3 Nb 2/3 )O 3 ‐Pb(Zr,Ti)O 3 (PMN‐PZT) ceramics have been used to fabricate the 31‐mode type‐I PEHs operating at resonance frequency. [ 98 ] The d 31 × g 31 value was also considered as FOM on for this PEH. [ 98 ] The d 31 value of the textured PMN‐PZT ceramic considerably increased in compared with that of PMN‐PZT ceramic, although the increase in g 31 of the textured PMN‐PZT ceramic was not significant owing to its large ε r value.…”

[ 98 ] For the multilayer‐textured PMN‐PZT specimen, the d 31 and g 31 values increased and decreased n times, respectively, where n is the number of multilayers, indicating that the d 31 × g 31 value is the same as that of the single‐layer specimen.…”

[ 98 ] However, with an increase in the number of layers, the output current of the PEH increased owing to an increase in d 31 , whereas output voltage decreased owing to a decrease in g 31 .…”
