Sound-based Predictive Maintenance
- Survey of potential sensor modalities (sounds, ultrasounds, vibrations) and related work (e.g., wind turbines)
- Starting with sound: Piezo contact mics/transducers, MEMS sensors
- Characterization of state based on known signatures (classification problem)
- Characterization of state transitions (HMM)
- Experimentation on Coffee machine/Blender/3D printer at PitLab
- 1..k sensors; Local/cloud-based processing.
- Experimentation on roller compacter/tableting machines at NN
