Abstract:Multi‐material direct ink writing (DIW) of smart materials opens new possibilities for manufacturing complex‐shaped structures with embedded sensing and actuation capabilities. In this study, DIW of UV‐curable piezoelectric actuators is developed, which do not require high‐temperature sintering, allowing direct integration with structural materials. Through particle size and ink rheology optimization, the highest d33*g33 piezoelectric constant compared to other DIW fabricated piezo composites is achieved, enab… Show more
