Sensor capable of measuring from -200ºC to 450ºC submitted for patent

Sensor capable of measuring from -200ºC to 450ºC submitted for patent

The group that developed the new technology consists of Miguel Neto, Filipe Oliveira, both researchers at CICECO, as well as Rui Ramos e Silva, professor and director of DEMaC, Bernardo Tavares (a PhD student at DEMaC), and technician Jacinto Alves. Miguel Neto, a member of the team, highlights the potential of the sensor: "This is the first time a temperature sensor has been developed that allows measurement, with or without contact, over a wide range of temperatures, from cryogenic temperatures (around -200ºC) to about 450ºC, in particularly harsh environments. The sensor's manufacturing method is also protected by this patent application and results from years of research by our group."

Due to their small size and quick response to minor temperature variations created by different heat transfer processes, these sensors are presented by the research team as the ideal solution for numerous applications. Their high chemical inertia and inherent biocompatibility enhance their use in platforms for immobilizing biomolecules, detecting chemical reactions in processes where heat exchange occurs, and in chemical and biological environments. Their high mechanical robustness and resistance to ionizing radiation also allow these sensors to be used in the mechanical, nuclear, and aerospace industries.

This technology participated in the UI-TRANSFER project for the transfer and valorization of scientific knowledge, driven by the University of Aveiro, University of Trás-os-Montes, University of Porto, TecMinho, and University of Coimbra. Through this project, the technology received support for proof of concept, having prototyped the application of this sensor in personal protective equipment, specifically in a firefighter's helmet for combating structural fires, with the aim of increasing operational safety during search, rescue, and firefighting tasks.

Given the numerous application possibilities of this technology, contacts have been developed with companies to apply this knowledge and use this sensor in real situations. Currently, a Portuguese company is testing the technology, particularly for monitoring and early detection of fires in rural and/or forest areas and in personal protective equipment. However, given the characteristics of this sensor, many other possibilities and commercial applications can still be anticipated.

The research group is currently working on scaling up the technology and applying it to other systems.

This technology has been subject to a national patent application, and international protection has been advanced via the Patent Cooperation Treaty (PCT), the International Patent System, which allows for extended future protection of this technology in different territories.
