Wearable Electronics and Self-Powered Sensors

Dear Colleagues,

The advancement of the Internet of Things (IoT), big data, and artificial intelligence depends on a broadly distributed sensing network, driven by energy storage units that have finite lifespans and environmental impacts. The wide distribution and high mobility of these sensors necessitate renewable, distributed energy sources to ensure the success of the IoT and sustainable human development. Mechanical energy has emerged as the most abundant renewable resource in various environments and is unaffected by weather conditions. This Special Issue, “Wearable Electronics and Self-Powered Sensors”, explores harvesting ambient mechanical energy (e.g., body motion) to create battery-free, autonomous systems. Core technologies, such as Triboelectric Generators (TENGs) and Piezoelectric Generators (PENGs), enable intrinsically self-powered sensing for physiological, biochemical, and environmental parameters. Innovations in flexible materials and fabrication facilitate wearable integrated technologies (patches, e-textiles). Key challenges include system integration (harvesters, power management, sensors, ultra-low-power electronics, and wireless communications like BLE/NFC) into robust, autonomous packages. Addressing stability, biocompatibility, and scalable manufacturing is crucial for deployment. The Special Issue highlights self-powered technology's potential to enable pervasive, sustainable wearable and IoT sensing networks, which are essential for future digitalization and societal progress.

Yours faithfully,

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 250 words) can be sent to the Editorial Office for assessment.

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. Sensors 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 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.
