“…Wang et al measured the nonlinear behavior of PZT 3203 HD from Motorola, classified as soft PZT ceramic, up to an electric field of 0.15 kV mm −1 by measuring the tip deflection and blocking force of cantilever beams using an optical fiber displacement sensor and a force load cell, respectively [17]. The results were compared to nonlinear analytical solutions by Chattaraj et al [18] and Yao et al [19]. The behavior of 'soft' piezoelectric ceramics (PZT5H from Morgan Matroc, PZT 3203 HD from Motorola and PK1550 from Piezo Kinetic Inc.) at a sinusoidal electric field up to 0.14 kV mm −1 was studied by Kugel et al using strain gauges [20].…”

In this paper, we compare the performance of 8 PZT ceramics and one PMN-PT material for typical bending actuator applications. This includes the measurement of nonlinear transverse charge coefficient at high electric field strength and related quantities such as the Young's modulus, relative permittivity, coercive field and their temperature dependencies, and the Curie temperature. Most materials show much higher strains than what is expected from the datasheet values. We further study the operating region for fields against the polarization direction in different operating cycles and demonstrate a long-term stable quick re-poling method which increases the operating range of negative-only cycles from 50% of E c to 66% of E c .

“…In addition, the electro-mechanical coupling coefficient affects the selfinduced electric displacement field. Chattaraj & Ganguli [23] analysed the performance of the piezoelectric bimorph actuator considering the self-induced electric displacement field at high electric field. Ahoor et al [91] performed dynamic analysis of bimorph actuators considering strain as a function of higher order electric field to express peizoelectric material non-linearity.…”

The paper aims at reviewing the modeling of piezoelectric laminated structures for stress distribution, vibration and noise control, shape control, health monitoring, and energy harvesting. Accurate modeling of piezoelectric laminates using linear and non-linear modeling techniques is essential at the high and low electric fields. The review is done in the field application of (1) different deformation theories (2) geometric non-linear theories (3) material non-linear models for the analysis of piezoelectric laminates. The literature review emphasizes using a higher-order non-linear model to analyze piezoelectric laminates and their effect on the composite structure.

“…One active layer contracts and the other expands when voltage is applied; thus, the bimorph bends. 19 This feature can be used to implement robotic-driven actuator and some mobile robots driven by piezoelectric actuators have been proposed. 1,[20][21][22] …”

In this study, a micro converter for driving a piezoelectric actuator is designed and implemented. The converter can produce 100 V, 80 Hz AC voltage from 3.7 V DC voltage. With regard to the requirements of micro mobile robots, the main contributions of this study are the design and implementation of a circuit topology supplying power for micro mobile robots at low power and the miniaturization of this topology to make it suitable for driving a centimeter-level robot. The 91 mg mass (excluding printed circuit board mass), 14 Â 12 Â 4 mm size, and 84.6% efficiency of the converter indicate that this circuit could be applied in micro mobile robots driven by piezoelectric actuators.
