Wireless and Integrated multi-parameters SAW Sensors Technologies for Implementation of a digital TWIN for electrical machines. – WISSTITWIN

The WISSTITWIN project aims at the development of an integrated network of smart sensors within an electrical machine, that will constantly stream data in order to update the numerical model of the electrical machine, known as its ‘digital twin’. Therefore, it is highly desirable to have access to a numerical model that is constantly updated through physical multi-parameters measurements provided by a network of sensors integrated in the real machine. For this purpose, we need reliable sensors that are compatible with an integration in low space and harsh environments, along with a reliable communication for data streaming. Thus, the project will exploit the combination of advanced functional materials and Surface Acoustic Wave technology to build batteryless and wireless multiphysics sensors with performances adapted to these constraints. A demonstrator of an electrical machine with several distributed sensors for temperature, stress, and magnetic field will be developed, along with its digital twin.
