Next-Generation Materials for Wearable Sensors

Dear Colleagues,

Wearable technology has revolutionized various sectors, from healthcare and fitness to entertainment and personal safety. Central to this revolution are wearable sensors, devices integrated into textiles or directly attached to the skin to monitor physiological signals, environmental conditions, and user activities. However, the effectiveness and widespread adoption of these devices are heavily dependent on the materials used in their construction. Next-generation materials for wearable sensors promise to address current limitations and open new horizons for functionality, comfort, and durability.

Traditional materials often fail to meet the multifaceted requirements of wearable sensors, such as flexibility, stretchability, biocompatibility, and mechanical robustness. Emerging materials like conductive polymers, nanomaterials (including graphene and carbon nanotubes), and advanced composites offer superior electrical, mechanical, and chemical properties. These materials enable the creation of sensors that are not only highly sensitive and accurate but also lightweight, flexible, and capable of conforming to complex body contours. Additionally, innovations in fabric-based sensors, where conductive fibers and electronic components are woven directly into textiles, have paved the way for seamless integration of sensors into everyday clothing, making the technology more user-friendly and discreet.

The development of next-generation materials also facilitates the creation of multifunctional sensors. For instance, materials that can simultaneously monitor multiple physiological parameters (such as heart rate, temperature, and sweat composition) and environmental factors (like UV exposure and air quality) are becoming increasingly feasible. Moreover, the use of biodegradable and sustainable materials aligns with the growing emphasis on environmental responsibility in technology development.

This Special Iaims to explore the latest advancements in materials science that drive the innovation of wearable sensors. It will cover a broad spectrum of topics, including the synthesis and characterization of novel materials, their integration into wearable devices, and their applications in real-world scenarios. By highlighting cutting-edge research and developments, this Special Iseeks to foster a deeper understanding of the role of advanced materials in the future of wearable technology.

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.
