Piezoelectric Materials and Applications

Dear Colleagues,

Piezoelectric materials have been of interest for many decades now in the framework of several applications fields, ranging, for instance, from sonar, historically, to integrated sensors and actuators more recently, along with biomedical applications. Indeed, with the growing interest in high-efficient compact actuators and micro-electromechanical systems (MEMS), piezoelectric material elaboration along with use in innovative applications (memory, energy harvesting, actuators, etc.), such materials and devices have received increasing attention, yet there is still large room of improvement for a better understanding of processes and physical effects of such transducers, also including current socio-economic stakes such as SDGs. Thus, this Topic aims to gather cutting-edge progress or topical reviews in the field of piezoelectric materials and their application.

Potential topics may cover but are not limited to:

• Lead-free piezoelectric materials
• Piezoelectric polymers
• Energy-efficient synthesis and fabrication of piezoelectric materials
• Small and large-signal characterization
• Analytical and numerical modeling
• Application in actuators
• Piezoelectric MEMS and NEMS
• Energy harvesting
• Energy and information storage (FRAM, etc.)
