Preface: Proceedings of the 11th International Electronic Conference on Sensors and Applications ^†

This issue of Engineering Proceedings gathers the papers presented at the 11th International Electronic Conference on Sensors and Applications (ECSA-11), held online on 26–28 November 2024, through the sciforum.net platform developed by MDPI. The annual ECSA conference was initiated in 2014 on an online basis only, to allow participation from all over the world with no concerns of travel and related expenditures. This type of conference looks particularly appropriate and useful because research related to sensors is still rapidly growing, and a platform for a direct exchange of information about the latest findings can provide a further burst in the development of novel ideas.

This year’s edition saw a continuously increased collaboration among the authors and the audience, through live session presentations of a limited number of contributions selected among the around 100 submissions, all formerly reviewed and accepted by the Chairs and/or by the Conference Committee members. Video recordings of the sessions and open access to papers and presentations can be found online at https://ecsa-11.sciforum.net/, accessed on 23 April 2025.

ECSA-11 collected contributions concerning eight thematic areas which are deeply affected by the rapid development of sensors and data processing: Chemo- and Biosensors; Physical Sensors; Sensor Networks, IoT, Smart Cities and Heath Monitoring; Sensors and Artificial Intelligence; Smart Agriculture Sensors; Electronic Sensors, Devices, and Systems; Wearable Sensors and Healthcare Applications; Robotics, Sensors, and Industry 4.0. Two keynote presentations were also delivered by Maria Lepore, Professor at the Department of Experimental Medicine of the University of Campania “Luigi Vanvitelli”, and by Andreoni Giuseppe, Professor and Director of the Technology and Design for Healthcare (TeDH) Laboratory at Politecnico di Milano.

The Student session gathered sixteen submissions, all competing for a Student Award. After the conference, the Chairs unanimously decided the winner of this competition to be Stephanie Lopes Morais from Instituto Politécnico do Porto, for her contribution titled “Electrochemical genosensors as a new approach on plant DNA detection and quantification for honey authentication”. Another award was established for the Best Contribution to the Conference, and was granted to Moshe Avraham et al. from Technion—Israel Institute of Technology, for their contribution titled “The Influence of MIM Metamaterial Absorbers on the Thermal and Electro-Optical Characteristics of Uncooled CMOS-SOI-MEMS Infrared Sensors”, and to Grzegorz Madejski et al. from Blekinge Institute of Technology, for their contribution titled “Lens Distortion Measurement and Correction for Stereovision Multi-Camera System”. Our sincere congratulations to the awardees for the great results achieved in their research activities and for the enthusiastic presentations during the live sessions.

A companion Special Issue of Sensors, see https://www.mdpi.com/journal/sensors/special_issues/L2NVEL3P7O, accessed on 23 April 2025, will collect full-length versions of the accepted papers.
