Design and optimization of piezoelectric actuators for microflap-embedded micropumps

Advances in Mechanical Engineering, 2023
In this paper, we propose a new method to use cost-effective multi-sheet off-the-shelf piezoelectric material (e.g. PZT) as an actuator for micropumps.

Domain evolution of BaTiO3 ultrathin films under electric field: a first-principles study

, 2006
A first-principles-derived method is used to study the morphology and electric-field-induced evolution of stripe nanodomains in (001) BaTiO3 (BTO) ultrathin films, and to compare them with those in (001) Pb(Zr,Ti)O3 (PZT) ultrathin films.

Voltage-induced strain to control the magnetization of bi FeRh/PZT and tri PZT/FeRh/PZT layered magnetoelectric composites [PDF]

AIP Advances, 2020
The bi- and tri- layered magnetoelectric composites were fabricated from magnetic Fe49Rh51 and piezoelectric PbZr0.53Ti0.47O3 materials. It was shown the electric field-induced stresses reduce the magnetization around magnetic phase transition temperature of Fe49Rh51: by 5.4% for tri-layer PZT/FeRh/PZT composite and by 3.6% for bi-layer FeRh/PZT ...

Pixelation‐Free, Monolithic Iontronic Pressure Sensors Enabling Large‐Area Simultaneous Pressure and Position Recognition via Machine Learning

Advanced Functional Materials, EarlyView.
A pixelation‐free, monolithic iontronic pressure sensor enables simultaneous pressure and position sensing over large areas. AC‐driven ion release generates spatially varying impedance pathways depending on the pressure. Machine learning algorithms effectively decouple overlapping pressure–position signals from the multichannel outputs, achieving high ...
