Special Issue Information
Dear Colleagues,
Electronic nose (e-nose) and electronic tongue (e-tongue) systems are rapidly advancing as innovative chemical sensing technologies inspired by the human olfactory and gustatory systems. Through the use of multi-sensor arrays and advanced pattern recognition algorithms, these platforms can detect, classify, and quantify complex mixtures in gaseous or liquid phases, making them highly valuable in numerous real-world applications.
Enabled by progress in micro- and nanotechnology, MEMS-based sensors, nanostructured films, sampling systems, and flexible electronics have dramatically improved the sensitivity, selectivity, and miniaturization of these systems. Coupled with artificial intelligence (AI) and machine learning (ML), e-noses and e-tongues now enable robust data analysis of dynamic and noisy environments. Further developments in the Internet of Things (IoT), edge computing, and cloud integration have paved the way for real-time, remote, and distributed sensing. Wearable devices, such as epidermal patches, smart textiles, and electronic tattoos, are enabling continuous monitoring in healthcare and consumer applications.
Of particular interest is the deployment of electronic noses and tongues on unmanned aerial vehicles (UAVs) and drones, which provides new capabilities for airborne sensing and mobile environmental diagnostics. These integrated systems can be used to monitor air quality, detect gas leaks, track agricultural emissions, or support search and rescue missions involving hazardous gases or contamination zones.
This Special Issue will showcase the most recent advances in the design, fabrication, integration, and application of e-nose and e-tongue systems across sectors, including healthcare, food safety, environmental monitoring, agriculture, and smart industries. We welcome both fundamental research and applied innovations that reflect the cutting edge of sensor technology and system integration.

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. 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.
