A piezoelectric meta‐transducer generates an ultrasonic rainbow, steering guided elastic waves to different angles according to frequency. A dithering‐based binary electrode design enables a closer realization of the target wavenumber filter, improving directional purity and suppressing unwanted lobes. Numerical and experimental validation demonstrates

Paper‐Templated Porous Piezoceramics
ABSTRACT Targeted porosity design enables deliberate modification of piezoceramics to enhance selected functional properties. Here, we introduce a simple, efficient processing route for porous piezoceramics based on organic paper templating and demonstrate it for Ba(Zr,Ti)O3–(Ba,Ca)TiO3 (BZT–BCT).

Textured Piezoelectric Ceramics Printed With Baffled Nozzles
To better align platelet particles in additively manufactured textured ceramics, baffled nozzles were simulated and tested. The simulation included a novel CFD heuristic that considers the entire print path. Printed parts were characterized via microscopy, X‐ray diffraction, and electromechanically and results were compared to the simulation, finding ...
