Sub-Projects
The i³Sense project comprises five distinct subprojects, each focusing on various applications of sensors in wood construction and composite structures. Within each project, pioneering research concepts have been developed and are elaborated upon in the following sections
Comet Zentrum (K1)
„WOOD – transition to a sustainable bioeconomy“ wird im Rahmen von COMET – Competence Centers for Excellent Technologies – durch das BMK (Bundesministerium für Klimaschutz, Umwelt, Energie, Mobilität, Innovation und Technologie), BMAW (Bundesministerium für Arbeit und Wirtschaft) und den mitfinanzierenden Bundesländer Kärnten, Niederösterreich und Oberösterreich gefördert
Sub Projects
01 Sensing with wood
The project explores the utilisation of fundamental wood-physical phenomena to sense critical moisture levels, employs acoustic methods for detecting fractures in bulk wood, and aims to detect hygroexpansion and moisture levels at the wood-adhesive interface.
02 Cellulose and Fabric sensors
The project aims to develop sensors using renewable cellulose or fabrics, integrating them into composite structures, knitting conductive or piezoresistive yarns into textile structures for use as embedded sensors, and implementing embedded sensors to monitor cure progress, strain, crack propagation, humidity, and temperature in the composites
03 Functionalised glue lines
The project aims to utilise glue joints as sensors to monitor both physical and chemical phenomena, forming a sensor network. It seeks to detect moisture in engineered wood products, determine temperature, curing behavior, and crack propagation within the glue lines, evaluate the integration of printed sensors onto porous cellulosic substrates, and localise moisture uptake within engineered wood products.
04 Sensor Design, Development and Validation
The project focuses on developing suitable sensor designs tailored for fine structures, thin or porous substrates, or direct integration into the final product, ensuring optimal conductivity, flawlessness, absence of short-circuits, and reliability in measurement signals with homogeneity. It emphasises good adherence on the substrate, stability in mechanical and thermal aspects, and durability. Additionally, for market entry, it prioritises easy and simple production, scalability, and profitability. Sustainability is a key consideration, aiming for low-temperature and rapid processing, reduced energy consumption and material waste, halogen-free materials, and end-of-life options such as recyclability or biodegradability.
05 Exploration
The project embarks on a journey of exploration and innovation, beginning with the crucial phase of establishing proof of concept across various use cases. This involves rigorous testing and validation to ensure the feasibility and efficacy of the proposed solutions.
As part of this process, Living Lab tests will be conducted in both Wood Construction and the Composite field. These tests serve as pivotal milestones, providing real-world validation and insights that drive further development and refinement.
Beyond the initial proof of concept, the project is dedicated to identifying and exploring additional innovative applications. This includes comprehensive research to uncover new application fields and address emerging research needs.
To inform strategic decision-making, the project conducts thorough market analysis to understand market dynamics, trends, and opportunities. Additionally, efforts are made towards the diffusion of innovation, ensuring the widespread adoption and impact of project outcomes.
In parallel, a critical aspect of the project is the sustainability assessment. This involves the establishment of a robust Life Cycle Assessment (LCA) model to evaluate environmental impacts and inform sustainable practices. Milestones include the establishment of the LCA model and the subsequent delivery of a detailed assessment report.
Through these concerted efforts, the project aims to not only develop innovative solutions but also ensure their sustainability and impact, driving positive change in the industry and beyond.
