Special Issue Information

Dear Colleagues,

Recent progress in flexible piezoelectric transducer technology has been nothing short of revolutionary, ushering in a new era of innovation in energy harvesting and sensing applications. The ability to harness mechanical energy from everyday movements and convert it into electrical energy holds immense potential for powering various electronic devices sustainably. This progress has been fueled by advancements in materials science, particularly in the development of novel materials with enhanced piezoelectric properties and mechanical flexibility. Moreover, the synergy between piezoelectric materials and flexible electronics has opened up new avenues for the seamless integration of energy harvesting and sensing functionalities into flexible electronic systems. This Special Issue is dedicated to current research activities in flexible piezoelectric transducers and materials. It aims to provide a comprehensive platform for researchers to share their latest findings and insights into the piezoelectric material design, fabrication, characterization, and application of flexible piezoelectric devices. We welcome both review articles that offer comprehensive reviews of recent advancements and original research papers that present novel concepts, methodologies, and experimental results.

We invite contributions covering a wide range of topics, including, but not limited to, the following:

  • Novel materials synthesis and design strategies to enhance the piezoelectric performance and mechanical flexibility of flexible transducers.
  • Advanced fabrication techniques for the scalable and cost-effective production of flexible piezoelectric devices.
  • Integration strategies for combining flexible piezoelectric transducers with flexible electronics for multifunctional applications.

Applications of flexible piezoelectric transducers in energy harvesting, self-powered systems, health monitoring, human–machine interfaces, and environmental sensing.

To explore the nonlinear dynamics of a piezoelectric energy harvesting device, we consider the simultaneous parametric and external excitations. Based on Bernoulli–Euler beam theory, a new dynamic model is proposed taking into account the curvature of the beam, geometric and electro-mechanical coupling nonlinearities, and damping nonlinearity, with inextensible deformation. The system is discretized by using the Galerkin–Bubnov procedure and then is investigated by the optimal auxiliary functions method. Explicit analytical expressions of the approximate solutions are presented for a complex problem near the primary resonance. The main novelty of our approach relies on the presence of different auxiliary functions, the involvement of a few convergence-control parameters, the construction of the initial and first iteration, and much freedom in selecting the procedure for obtaining the optimal values of the convergence-control parameters. Our procedure proves to be very efficient, simple, easy to implement, and very accurate to solve a complicated nonlinear dynamical system. To study the stability of equilibrium points, the Routh–Hurwitz criterion is adopted. The Hopf and saddle node bifurcations are studied. Global stability is analyzed by the Lyapunov function, La Salle’s invariance principle, and Pontryagin’s principle with respect to the control variables. Full article
