Use Cases

To meet the needs of the major challenges of electronic based systems (EBS), the USE Lab will focus on following research topics:

      • Modelling, simulation and optimization of sensors and sensor systems including their environment
      • Large scale sensor deployment and seamless integration in environments, e.g. for surveillance and condition monitoring
      • Innovative power supply concepts including harvesting/storing technologies and low power sensor technologies
      • Low energy, low cost additive manufactured functional sensor layers and hybrid integration of discrete electronics, and energy management
      • Wireless connectivity and sensor communication
      • Semantic sensor networks including semantics modelling and annotation of large sensor data streams for eased use and setup of measurement systems

These research challenges can be tackled on different integration levels, from chip or packaging level to system level. A significant strength of the USE Lab is the ability to follow an integrated and holistic approach on different integration levels using following methods:

      • Multi-scale, multi-physical mathematical modelling and consideration of uncertainties on all scales and in all phases to allow for the development of accurate and efficient algorithms to extract the parameters of interest and to allow for utilization of methods for optimal design
      • Functional ink printing technologies in combination with advanced packaging concepts
      • Application of multiparameter sensing matrices to enable self-referencing and self-calibrating sensing systems for the analysis of complex environments
      • AI for analysing large stationary and transient data sets derived from multisensor matrices for enabling virtual and indirect sensing applications
      • Advanced signal processing methods including data compression, self-referencing, and self-calibration capabilities

As concrete development basis for the development of the methods 3 use cases (UC) with increasing levels of complexity are defined to make full use of the USE lab:

Aim is to provide an autarkic, wireless humidity and temperature sensors on a flexible substrate suitable to be integrated in smart textiles. This can be used for wearable devices but also in industrial textiles, e.g. for monitoring potential leaks (roofs, basins, etc) over large areas operating in a network. Such sensors will typically have a thickness below 1 mm and can be easily attached to surfaces. Methods developed in ubiquitous sensing lead to improved localisation capabilities of water leaks.

Sensors for condition monitoring purposes that can be integrated in structures or on surfaces of structures (e.g. industrial machinery, buildings, bridges, wooden constructions, etc.) and measure the strain and vibration. The ubiquitous sensing approach offers improved failure detection of machine parts and structures.

Detection of  presence and estimation of concentration of Volatile Organic Compounds (VOCs) and or acidic gases by means of multisensors based on colorimetric polymers  and utilization of machine learning algorithms, sensor networked based estimation of origin of gas source and monitoring of propagation.
