Special Issue Information
Dear Colleagues,
Stretchable conductive hydrogels represent a class of emerging materials that uniquely integrate electrical conductivity of traditional conductors with mechanical flexibility and biocompatibility of hydrogels. These materials have garnered significant attention in recent years, particularly in the development of flexible sensors and bioelectronic devices. Owing to their high water content, tunable mechanical properties, and soft tissue-like elasticity, conductive hydrogels can establish intimate and stable interfaces with biological tissues, thereby minimizing mechanical mismatch and enhancing signal fidelity in physiological monitoring applications. Moreover, their intrinsic stretchability allows them to accommodate dynamic deformations, such as bending, twisting, and stretching, which are commonly encountered in wearable and implantable systems. Through the incorporation of conductive fillers—such as carbon-based nanomaterials, metal nanowires, or intrinsically conductive polymers—hydrogels can be endowed with robust electrical pathways without compromising their softness. This synergistic combination of properties positions stretchable conductive hydrogels as promising candidates for next-generation biointegrated electronics, enabling applications ranging from electrophysiological signal acquisition to on-skin human–machine interfaces.
We look forward to your contributions.

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. Gels 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 2100 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.
