Flexible Piezoelectric Sensors and Devices

Dear Colleagues,

The recent development of the “Internet of Things” (IoT) suggests the growing importance of the development, integration, and system design of multifaceted wearable devices. The demand for maintenance-free, clean, and green renewable energy sources with re-charging options which are independent of weather conditions and fossil fuels providing long-term energy supply is becoming more and more urgent. Materials with ferroelectricity, a subset of piezo/pyroelectricity, enable various applications, including but not limited to non-volatile memory devices, temperature and tactile sensors, transducers, actuators, and energy harvesters. As a matter of fact, state-of-the-art technology seeks more attention on flexible ferro-, piezo-, and pyro-electric-based sensors and energy-harvesting devices, termed nanogenerators, which have been demonstrated to have excellent potential to harvest electricity from ubiquitous and abundant mechanical and thermal motions, respectively, and operate devices in a sustainable manner.

In this Special Issue, we are inviting research papers, communications, and review articles focusing on the following aspects:

• Innovative developments of flexible sensors and nanogenerators based on ferro-, piezo-, pyro-electricity, and hybrid mechanisms based on both experimental and theoretical study;
• From a materials point of view, devices based on inorganic, organic, and biodegradable materials;
• From an applications perspective, self-power technology, electronic skin, robotic applications, healthcare monitoring sensors, wireless power transfer systems, smart pavement monitoring systems, tire pressure monitoring systems, aerodynamics, and biomedical applications from tissue engineering to implantable 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. Micromachines is an international peer-reviewed open access monthly 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 2600 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.
