For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website. Research articles, review articles as well as short communications are invited. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. All submissions that pass pre-check are peer-reviewed. Manuscripts can be submitted until the deadline. Once you are registered, click here to go to the submission form. Manuscripts should be submitted online at by registering and logging in to this website. Attendees to PIEZO2021 will enjoy a 10% discount of the APC for publishing the work presented at the Conference. The editors are members of the European Institute of Piezoelectric Materials and Devices that is the co-organizer of the Conference “ PIEZO2021: Piezoelectrics for End Users XI”, 21–24 February 2021, University of Sassary, Italy. For this reason, the investigation of ecological materials, without lead (lead-free), has experienced great growth in recent years, and examples of commercial applications are currently available.Ĭontributing manuscripts and review papers on the topics of new lead-free compositions and processing routes for bulk ceramics, thin and thick films and composites, on the structural, mechanical, coupled phenomena, ferroelectric and dielectric characterization, on modeling, and on application-oriented studies of these materials are welcomed. Commercial devices use lead titanate zirconate ceramics, which are prepared from lead oxide, a highly toxic compound, which must be replaced in devices according to the most recent regulations in force, e.g., in the European Community. For this purpose, compulsorily, their processing has continuously been revised, and new cost-effective routes ensuring repeatability of the material production are tested.

However, they must comply with strict mechanical properties’ requirements for long endurance in use.

Good electromechanical properties are a good starting point for applications. Piezoelectric ceramics, as they connect electrical and mechanical magnitudes, are complex to design for devices. The limits of the use of piezoceramics are the limits of human ingenuity. In addition, these versatile materials have in recent years found new uses in the field of the clean and renewable energy production systems, e.g., as mechanical harvesters.

Further, piezoelectric scanners are a fundamental piece in all kinds of probe microscopes with a nanometer resolution. Indeed, telescopes use deformable mirrors containing hundreds of actuators. They have been classically used as sensors and actuators in all areas of daily life (telecommunications, industry, health, transport, etc.) and from the exploration of the universe to the exploration of the nanoworld. The poled polycrystalline ferroelectric materials, also known as piezoelectric ceramics, are the best example of multifunctionality.
