Functional Materials Promote Triboelectric Nanogenerator Toward High Performance and Multifunction

Dear Colleagues,

The rapid development of wearable electronics has created an urgent need for energy harvesting technology that can be rationally integrated into efficient, sustainable, and potable systems. In this case, triboelectric nanogenerators (TENGs) are expected to be a major impetus to such innovation because they can not only power a sensor by scavenging mechanical energies and transforming them into electricity but also act as the chemical/physical sensors themselves due to their intrinsic sensitivity towards the both the contact force and chemical reaction that occur at the triboelectric–piezoelectric interface.

In the past years, triboelectric nanogenerators have been widely studied for their advantages of easy design/manufacturing, small size, and flexibility in energy harvesting and environmental monitoring. However, reaching high performance for practical applications is still a huge challenge, as is integrating multiple functions into a single TENG device, especially for those with different or even opposite requirements in electrical properties. This Special Issue aims to cover the recent research progress of TENGs by presenting, in detail, their incorporation of various functional materials such as magnetic materials, ferroelectric materials, semi-conducitong materials, dielectric materials, and so on. It discusses their key roles in promoting operating principles, integration concepts, and performance enhancement strategies, with a focus on their theoretical innovation, structural simplification, function expansion, system integration, and performance improvement. In the present Special Issue, we welcome contributions from any groups in the field with the aim of giving a balanced view of the current state-of-the-art in this discipline.

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.
