Microphones and acceleration sensors can be used to "listen in" on machines and detect anomalies at an early stage, for example leaks from pneumatic actuators. Festo and partners are using the AI-Music4.0 research project to determine how innovative sensor data along with artificial intelligence (AI) could be used in industrial applications. This new quality of data processing directly at the components could lead to the secure, decentralised analysis and reliable forecasting of the status of components or systems.
