• Description:
  A capacitive load cell made using FlexPCB manufacturing technology, is shown to be a feasible approach for in-situ sensing of continuous mining vibration signatures. Capacitive sensors are known for being resilient to temperature variations and the chosen materials are widely available. A batch of example sensors are characterized with load frame testing. Changes in capacitance due to strain from applied force is measured with an embedded capacitance meter. Algorithms which accurately classify vibration signals to determine tool wear and material type are discussed. Considerations for device packaging and integration with commercially available cutting systems are given. [Description provided by NIOSH]
