Advanced Conductive Hydrogels for Next-Generation Wearable Biosensors

Dear Colleagues,

Conductive hydrogels represent a revolutionary class of materials uniquely positioned to overcome the critical limitations of traditional rigid electronics in wearable biosensing. Their intrinsic biocompatibility, tunable mechanical properties matching human tissue, excellent ionic/electronic conductivity, and versatile functionalization capabilities make them ideal for seamless, long-term integration with the dynamic human body. This Special Issue seeks to showcase cutting-edge research and reviews addressing the development, characterization, and application of advanced conductive hydrogels specifically for wearable biosensors. We invite contributions exploring novel hydrogel formulations (e.g., nanocomposite, double-network, and stimuli-responsive), innovative fabrication strategies (3D printing and in situ formation), and enhanced functionalities (self-healing, adhesion, and environmental stability). A key focus is the integration of these hydrogels into robust, sensitive, and selective biosensing platforms for continuous, non-invasive monitoring of biomarkers in biofluids (sweat, saliva, tears, ISF, etc.) or physiological signals (ECG, EMG, strain, pressure, temperature, etc.). Manuscripts addressing critical challenges like long-term stability in vivo, signal drift mitigation, biocompatibility assessment, power integration, and scalable manufacturing are particularly encouraged. This multidisciplinary issue aims to advance the frontier of soft, skin-conformable electronics, accelerating the realization of personalized healthcare solutions.

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. Biosensors 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 2200 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.
