Nonlinear bending deformation of soft electrets and prospects for engineering flexoelectricity and transverse (d31) piezoelectricity.

Soft Matter, 2018
Soft materials that exhibit electromechanical coupling are an important element in the development of soft robotics, flexible and stretchable electronics, energy harvesters, sensor and actuators. Truly soft natural piezoelectrics essentially do not exist

Simulating the Effects of Porosity on the D31 Piezoelectric Coefficient of Polyvinylidene Fluoride

ASME 2022 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2022
Abstract A piezoelectric, thin film polyvinylidene fluoride (PVDF) material was developed for application as a blood pressure/flow sensor within an artificial heart. In an effort to increase the piezoelectric coefficient, d31, and maximize the sensitivity of the PVDF material, nanoscale pores were introduced into the thin films.

An Attempt to Topology Optimize 3D Printed Piezoelectric Composite Sensors for Highest D31 Output

ASME 2021 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2021
Abstract By adopting topology optimization based on numerical solvers, the geometries of the piezoelectric sensors can be optimized to produce higher electrical output in a certain loading directions. 2D topology optimization and simulation studies are carried out with ANSYS using Piezo and MEMS extensions for coupled systems.

Preparation and electromechanical properties of a piezoelectric ceramic dome-like actuator with d31 gradients

Current Applied Physics, 2011
Abstract We report fabrication by a traditional ceramics process of a dome-like actuator composed of two PZT piezoelectric ceramics, one doped with donors (La 3+ and Nb 5+ ) and the other with acceptors (Fe 3+ and Ni 2+ ). The results show that at 120 °C, the resistivity of PZT doped with La 3+ and Nb 5+ is three orders of magnitude more than ...
