Piezoelectric composites are thriving in the field of self-sustainable wearable electronics owning to their intrinsic capability of converting mechanical energy to electrical energy and vice versa. Additive manufacturing (AM), also known as 3D printing, refers to as a category of robust techniques in manufacturing 3D architected piezoelectric structures. Nonetheless, most of the 3D printing techniques often face the inherent speed-accuracy trade-off. Herein, we report rapid, high-resolution 3D printing of architected piezoelectric composite structures using micro continuous liquid interface production (CLIP). Resins with chemically functionalized piezo nanoparticles, including barium titanate (BTO) and lead zirconate titanate (PZT), were prepared and printed continuously at high printing speeds. Quantitative studies on the 3D printed BTO and PZT composites reveal their piezoelectric performance comparable to other stereolithography-based works but come at >10 times faster speeds. Proof-of-concept demonstrations further validate its capability in a variety of flexible and wearable sensing applications.
