The Smart Structures and Systems Laboratory (S3 Lab) is situated at Politecnico di Torino, in the Department of Mechanical and Aerospace Engineering.

The S3 Lab accommodates state-of-the-art facilities, cutting-edge instrumentation, and advanced test benches to enable the design, modeling, and characterization of multifunctional and integrated structures and systems with advanced performance metrics, based on innovative materials and production processes.  

Research and Development

Structural mechanics. Our research aims to devise innovative solutions with high specific strength, lightweight design, functionally graded structures for property transition, multi-material design, and multifunctional component design. 

Integrated systems. Our work concentrates on developing advanced components with environmental adaptability, including sensing, actuation and control mechanisms. We also focus on flexible components with innovative measurement systems, such as e-textiles, smart fabrics, and flexible electronics. Our research further explores the development of components with special performances, such as biocompatibility and wearability.  

Applications. Our team applies these research outcomes to create structural parts for ground, air, and space vehicles, intelligent components for self-diagnostics based on advanced production processes, wearable systems for the human body, human-machine interfaces, multi-material components with high-energy absorption, conveyor belts, intelligent flexible components, and other applications.

Methods and scientific background

Our applied methodologies involve the application of numerical finite element modeling, rigid body models, and the formulation of multiphysical analytical models to support our design efforts. Additionally, we employ experimental methods of analysis, which include traditional typologies for the static and dynamic characterization of materials, modal analysis, and analysis of fatigue behavior. Specialized typologies are also utilized for the validation of multiphysical interactions, such as electrical, thermal, fluidic, and mechanical analysis. To support specific experimental analyses, we have self-built test benches available for evaluating the performance and wear of smart fabrics, validating the functionality and damage of sensorized flexible materials, and other related tests.
