Bicontinuous piezoelectric composites, consisting of a continuous piezoelectric ceramic skeleton and a flexible polymer phase interconnected in three-dimension (3D), possess an excellent property combination of mechanical flexibility and piezoelectricity. The piezoelectric performances of these materials are dependent on the meso-scale geometry of the interface between the active piezoelectric ceramic phase and the passive polymer phase. In this research, we investigate the design and fabrication of bicontinuous piezocomposites with tailorable hydrostatic performance utilizing a suspension enveloped projection stereolithography process (SEPS). Triply periodic cellular structures are used to design the active piezoelectric ceramic phase, due to the large elastic constants with respect to their rod-connected counterparts. Post processes including debinding, sintering, poling and polymer infiltration are presented. Mechanical and piezoelectric properties of the achieved bicontinuous piezocomposites are analyzed through experimental characterization and finite element modeling.
