Abstract Scope |
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. Three-dimensional (3D) printing is being extensively adopted in manufacturing 3D piezoelectric structures that deliver anisotropic and directional responses, yet most 3D printing techniques face the speed-accuracy trade-off and either limit themselves to macroscale devices or require prolonged fabrication time. On the contrary, micro continuous liquid interface production (μCLIP) has shown its efficacy in high-speed, high-quality productions of 3D structures.
Here, we report rapid, high-resolution 3D printing of piezoelectric composite structures via μCLIP. We formulated functionalized resins utilizing piezoelectric nanoparticles (PiezoNPs) like barium titanate (BTO) with concentrations up to 30 wt% to print 3D structures that deliver piezoelectric performance comparable to other vat-polymerization-based works at unprecedented speeds of up to ~ 60 μm/s. Proof-of-concept demonstrations further validate their capability in flexible and wearable sensing applications. |
