Mechanical Monolithic Sensors

Project Description

The Mechanical Monolithic Sensors project aims to innovate the field of precision mechanical sensors for the measurement of low frequency displacements and accelerations through the development, production and marketing of a monolithic mechanical sensor, based on the innovative UNISA Folded Pendulum technological platform, invented and consolidated, also internationally, by the startup Advanced Scientific Sensors and Systems s.r.l., a spin-off of the University of Salerno. As part of this project, this platform was aimed at the simple and direct implementation of a broadband, high sensitivity, compact, lightweight and low cost sensor for local and/or distributed monitoring applications.

The realization of the project was facilitated thanks to the contribution coming from the Notice for the creation and consolidation of innovative start-ups: “Campania Start Up Innovativa”, implemented by the POR FESR of the Campania Region and financed by the European Union, by the Italian State and by the Campania Region for a contribution of € 53,656.56.

 

Goal

The goal of the project is the development, production and marketing of a mechanical monolithic position and acceleration sensor, characterized by broad band in the low frequency region and high sensitivity, compact, light and cheap, usable for high quality locally and/or distributed monitoring, aimed at safeguarding and securing architectural and monumental structures belonging to the historical/artistic heritage, and, more generally, for large civil infrastructures (bridges, dams, buildings, etc.).

The features of this innovative sensor allow users to create high-precision and low-cost monitoring systems for the study of broadband and low-frequency vibrations of structures, which have been difficult to acquire due to the absence of suitable sensors on the international market. making it possible to evaluate in real time their static and dynamic behaviour in order to prevent collapses and / or other types of damage, with a correct and targeted structural maintenance, reducing the risks for the heritage and for the population.

 

Results

The innovative mechanical sensor developed has characteristics that allow its direct application in the field of the preservation of historical and artistic heritage, guaranteeing easy planning of local and/or distributed monitoring networks.

The modular architecture of the sensor allows both its simple application and specialization to solve specific problems and, at the same time, the marketing of individual parts constituting the sensor, such as for example the monolithic mechanical oscillator or the mechanical signal readout system, allowing also the customer to operate specializing it to his specific application.

The sensor produced in the context of this project, model GJ17, is already present on the international market, presented by Advanced Scientificic Sensors and Systems s.r.l. at international fairs in Europe and in USA, which made it possible to make its features known and to promote their marketing also for industrial and scientific monitoring networks.
