The session focuses on sensors and experimental methodologies in preventive conservation, particularly for microclimate monitoring, vibration and shock analyses, and localization of artwork. Regarding microclimate monitoring, specific attention is given to case studies involving the measurement of physical and chemical parameters, as well as transduction principles, procedures, and data processing methods.

A critical aspect concerns the movement of artifacts during transportation, including localization, especially in the case of loans for temporary exhibitions. The approach encompasses various facets, such as device features, characterization, measurement methods (including uncertainty evaluation), validation and intercomparison studies.


Submissions are welcome on, but not limited to, the following topics:

  • Physical and chemical parameters measurement for microclimate monitoring;
  • Preventive conservation during exposition, loan and transport of artwork;
  • Innovative transduction principles and devices for preventive conservation;
  • Emerging technologies for microclimate monitoring;
  • Measurements and optimization strategies for preventive conservation;
  • Algorithms and procedures for microclimate monitoring;
  • Development of measurement and data analysis protocols;
  • Intercomparison and accuracy studies;
  • Best practices, guidelines and legislation for CH.


Carlo Trigona, presently serves as an Associate Professor of Electronic Instrumentation and Measurements at the University of Catania, Italy, within the Department of Electrical, Electronic, and Computer Engineering (DIEEI). His academic journey began with the attainment of an M.S. degree (cum Laude) in Automation Engineering and Control of Complex Systems from the University of Catania in 2006. Continuing his pursuit, he embarked on his Ph.D. studies at the same university from 2006 to 2009, culminating in the achievement of a Ph.D. degree in Electronic, Automation, and Control of Complex Systems in 2010. His post-doctoral endeavors took him across Europe. From 2010 to 2011, he served as a post-doc and lecturer at the University Montpellier II – LIRMM (France). Subsequently, he continued his post-doc and lecturer roles at DIEEI, University of Catania, from 2011 to 2017. In 2017 to 2018, he furthered his research as a post-doc at the Chemnitz University of Technology (Germany). Returning to the University of Catania, he served as an Assistant Professor of Electronic Instrumentation and Measurements at DIEEI from 2018 to 2020. Continuing his academic progression, he held the position of tenure-track Professor of Electronic Instrumentation and Measurements at the same department from 2020 to 2023. He actively engages in numerous national and international academic and engineering projects, contributing as both coordinator and partner. Additionally, he significantly impacts the Instrumentation and Measurement community through various activities, including editorial roles and serving as a reviewer for esteemed journals from 2006 up to the present. Professor Trigona has received several awards for his research endeavors, notably the 2020 IEEE I&M Outstanding Young Engineer Award for his exceptional contributions to advancing I&M concepts in sensors and transducers for energy harvesting. Regarding his research profile, Prof. Trigona's first paper surfaced in 1997, and presently, he co-authors more than 250 scientific publications with over 2200 citations. These contributions span chapters in books, papers in international journals, proceedings of international conferences, trademarks and patents. His research interests encompass sensors, transducers, MEMS, NEMS, fluxgate magnetometers, energy harvesting, as well as innovative areas such as green and biodegradable sensors and transducers based on living organisms.

Anna Maria Gueli, is a Professor in Applied Physics at the University of Catania and the Head of PH3DRA (Physics for Dating Diagnostics Dosimetry Research and Applications) laboratories, included in the European Research Infrastructure for Heritage Science through the INFN Cultural Heritage Network (CHNet). Her research mainly concerns the dating of archaeomaterials through stimulated luminescence (TL&OSL) and analytical techniques in Art Conservation. These last include interdisciplinary approaches to microclimate monitoring and applied colorimetry starting from the optical properties of materials. She received the Master in Physics from the University of Catania discussing a thesis in archaeometry related to the experimental research performed during the Erasmus Project at the University of Bordeaux (France). In this last academy she obtained the DESS (Diplôme d'études supérieures spécialisées) in Physical Methods in Archaeology and Museography. After obtaining a scholarship from INFM, she received a Ph.D. in Physics from the University of Catania with a thesis in radiation dosimetry, mainly focused on archaeological dating. She obtained a post-doc scholarship from CNR and a research grant from the University of Catania. She was Chercheur Associé of the European program GRUNDTVIG Adult Education Program and Professeur Invitée à temps plein of the University of Bordeaux. She coordinated the activities of Italian researchers within the European Research Group GdRE-TCA “Ceramic Building Materials and new dating methods”. Elected member of the Executive Council of the Italian Association of Archaeometry (AIAr) covering the role of General Secretary and Treasurer. Professor Gueli is the Catania’s University Delegate in the Permanent Thematic Working Group of the Regional Strategy of the Innovation for the Intelligent Specialization in the area of "Tourism, cultural heritage, culture" and in the National Technological Cluster Project TICHE - Technological Innovation in Cultural Heritage.
