Special Issue Information

Dear Colleagues,

Piezoelectric materials, known for their ability to convert electrical energy into mechanical motion and vice versa, have revolutionized various fields of engineering and technology. Today, piezoelectric actuators, motors, and transducers are applied across diverse industries. From precise positioning in nanotechnology to ultrasonic imaging in medical diagnostics, the versatility and efficiency of piezoelectric devices have significantly impacted modern engineering solutions. This Special Issue aims to provide insights into the design considerations, operational mechanisms, and practical implementations of innovative piezoelectric devices.

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. Applied Sciences 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.

Abstract
In this study, to develop the composition ceramics for the application of an ultrasonic transducer device for alleviating temporomandibular joint disorder pain, Pb0.88 (La0.6 Sm0.4)0.08(Mn1/3 Sb2/3)0.02Ti0.98 O3 ceramics were manufactured [...] Read more.
In this study, to develop the composition ceramics for the application of an ultrasonic transducer device for alleviating temporomandibular joint disorder pain, Pb0.88 (La0.6 Sm0.4)0.08(Mn1/3 Sb2/3)0.02Ti0.98 O3 ceramics were manufactured using CuO as sintering aids, and their piezoelectric and resonant properties were investigated. For the specimen sintered at 1200 °C, excellent values of piezoelectric properties appeared: the dielectric constant (εr) of 202, piezoelectric constant (d33) of 56 pC/N, first and third overtone electromechanical coupling factors kt of 0.548 and kt3 of 0.219, and first and third overtone mechanical quality factors Qmt1 of 345 and Qmt3 of 292, respectively, made the device suitable for application as an ultrasonic transducer. When the length of the piezoelectric device was 7.7 mm, the first and third overtone electromechanical coupling factors kt1 of 0.555 and kt3 of 0.196, first and third overtone mechanical quality factors Qmt1 of 381 and Qmt3 of 393, and first and third overtone dynamic ratios (D.Rs) of 63.7 (dB) and 37.7 (dB) were suitable for device applications as an ultrasonic transducer and facial skin massage, respectively.
