Piezoelectric oxide films and nanostructures have allowed tremendous development in the fabrication of different devices and applications due to their intrinsic properties such as high quality, good chemical and temperature stability, and low costs of processing, among others. Moreover, advances in micro- and nanofabrication technologies have opened the possibility of implementing a large-scale integration of miniaturized piezoelectric materials into innovative electromechanical devices with nanosized moving parts (MEMS/NEMS), with prospective applications in electronics, biology, and medicine.
The fine control of the stoichiometric ratio between functional oxide precursors allows the preparation of novel piezoelectric oxide materials with different crystalline structures and dimensionality. Several attempts to increase their quality factors and piezoelectric coefficients regarding temperature have been reported, but more investigations are necessary to realize practical applications. In spite of several materials’ deposition processing, patterning, and integration strategies, only a few piezoelectric MEMS devices have been successfully commercialized. Several challenges that currently remain are (i) the use of low-cost chemical solution methods for the deposition of uniform and high-quality piezoelectric films and nanostructures, (ii) the development of techniques for material deposition in thin film form with properties close to those of bulk materials, and (iii) the use of nontoxic, light, and abundant elements.
This Special Issue of Nanomaterials aims to cover the most recent advances in the synthetic approaches for the preparation and integration of piezoelectric and ferroelectric oxide films and nanostructures on technological substrates, relevant to integrating sensing functionalities in MEMS and other resonant systems. Novel or improved applications of the piezoelectric oxide nanomaterials in different areas are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
