In this paper, we consider transverse steady oscillations of a piezoactive bimorph in the formulation plane deformation. The problem is solved within framework linear thermoelectroelasticity, while temperature separately and distribution taken into account constitutive relations electroelasticity. On basis Kirchhoff-Love type hypothesis for mechanical quantities symmetric quadratic electric pot...

Although widely investigated, novel electromechanical actuators with high overall actuation performance are still in urgent need for various practical and scientific applications, such as robots, prosthetic devices, sensor switches, and sonar projectors. In this work, combining the properties of unique environmental perturbations-actuated deformational isomerization of polydiacetylene (PDA) and...

The paper presents the assessment of electric output rendered by a unimorph and bimorph piezoelectric harvester, with one two active piezoceramic wafers, using numerical simulations. Expected sinusoidal voltages were obtained in time-dependent study, time step corresponding to eigenfrequency found after conducting an Eigenfrequency study. terminal agree Euler-Bernoulli beam theory distance laye...

This paper explores a concept for dynamic amplification of piezoelectric actuator motion using repeated impacts between the active transducer and compliant mechanism. The design shows good performance in amplifying vibration lead–zirconate–titanate (PZT) bimorph while down-converting output frequency from more than 150 Hz to less 20 Hz. A simple model is used identify conceptual opportunities i...
