Special Issue Information

Dear Colleagues,

Piezoelectric materials are widely used in sensors, actuators, transducers, manipulators, and robots. As a typical functional material, piezoelectric materials have the merits of small size, high power density, high displacement resolution, high sensitivity, and more. The research of piezoelectric materials is mainly focused on the development of new materials and their new applications. Furthermore, the applications of piezoelectric materials include piezoelectric robots, piezoelectric actuators, ultrasonic motors, piezoelectric sensors, piezoelectric transducers, nano manipulations, piezoelectric microjets, piezoelectric pumps, and more. The piezoelectric robot is a new concept for the robot using the piezoelectric element as the actuating element. The unique merits of this approach include a large working range, high resolution (nanometer level), large load-carrying ability, and multi-DOF motion. The demand for robots with high performance in cross-scale and multi-DOF motion has been continuously increasing in recent years, which the piezoelectric robot can satisfy well. This Special Issue aims to provide a forum for researchers to generate, exchange, and follow up the ideas, recent trends, and achieved results related to new piezoelectric materials and new applications of piezoelectric materials. Original innovative research works from both academia and industry are welcomed. Topics of interest include, but are not limited to:

Force sensors on climbing robots give important information to the robot control system, however, off-the-shelf sensors can be both heavy and bulky. We investigate the optimisation of a lightweight integrated force sensor made of piezoelectric material for the multi-limbed climbing robot MAGNETO. We focus on three design objectives for this piezoelectric component. The first is to develop a lightweight component with minimal compliance that can be embedded in the foot of the climbing robot. The second objective is to ensure that the component has sensing capability to replace the off-the-shelf force sensor. Finally, the component should be robust for a range of climbing configurations. To this end, we focus on a compliance minimisation problem with constrained voltage and volume fraction. We present structurally optimised designs that satisfy the three main design criteria and improve upon baseline results from a reference component. Our computational study demonstrates that the optimisation of embedded robotic components with piezoelectric sensing is worthy of future investigation. Full article

Nonlinear piezoelectric materials are raised as a great replacement for devices that require low power consumption, high sensitivity, and accurate transduction, fitting with the demanding requirements of new technologies such as the Fifth-Generation of telecommunications (5G), the Internet of Things (IoT), and modern radio frequency (RF) applications. In this work, the state equations that correctly predict the nonlinear piezoelectric phenomena observed experimentally are presented. Furthermore, we developed a fast methodology to implement the state equations in the main FEM simulation software, allowing an easy design and characterization of this type of device, as the symmetry structures for high-order tensors are shown and explained. The operation regime of each high-order tensor is discussed and connected with the main nonlinear phenomena reported in the literature. Finally, to demonstrate our theoretical deductions, we used the experimental measurements, which presented the nonlinear effects, which were reproduced through simulations, obtaining maximum percent errors for the effective elasticity constants, relative effective permittivity, and resonance frequencies of 0.79%, 2.9%, and 0.3%, respectively, giving a proof of the potential of the nonlinear state equations presented for the unifying of all nonlinear phenomena observed in the piezoelectric devices.
