Piezoelectric/Electrostrictive Device Material Selection TRIZ Cases
- Lead-Free Piezoelectric Composition With Template-Oriented Crystals
A lead-free Na-K-Nb-Sb-Sr-Zr-CuO piezoelectric composition uses template-guided crystal orientation to retain strong piezoelectric properties.
- 3D-Printed Ferroelectric Metamaterial With In-Situ Poling and Toughness
Intercalated electrodes and Li-KNN polymer layers enable true 3D ferroelectric printing with high piezoelectric response and bone-like toughness.
- Ytterbium-Doped AlN Piezoelectric Films for High-Output MEMS
A tuned Yb-doped AlN composition and lattice ratio boosts d33 and g33 while improving crystallinity for high-frequency MEMS sensors and actuators.
- Flexible Piezo-Composite Transducer for Curved Surface Sensing
A PZT-5H and PDMS transducer with flexible AgNW electrodes conforms to irregular surfaces while preserving sensitivity, bandwidth, and contact reliability.
- Porous Ceramic Pre-Firing for Thick Acoustic Transducer Bodies
Staged pre-firing removes binders and pore formers gradually, preventing cracks and warping in thick porous ceramics for direct electroding.
- Piezoelectric Actuator Electrode Design for Stress Reduction
Local quality design prevents stress and cracks in piezoelectric layers while maintaining dielectric strength.
- Piezoelectric Resin Blend Decoupling Mechanical and Electrical Properties
A piezoelectric resin blend combines active polymer with a matrix to modulate electrical output independently from mechanical strength.
- Piezoelectric Force Sensor With Insulating Adhesive
Insulating adhesive bonds the piezoelectric element to the base, preventing short circuit risks from conductive paste while maintaining mechanical strength.
- Multi-Piezoelectric Microcantilever Sensor for SPM Deflection
A microcantilever sensor uses multiple piezoelectric elements to detect deflection with high precision.
