Industrial Predictive Maintenance (PdM) 

Market feedback

Self powered sensing nodes are preferred Because:

​

  • Not always it is easy to connect a node to a power line.

​

  • Batteries are not a good solution because in many case the lifetime of the sensor node exceeds the battery lifetime and batteries replacement is expensive (labor time).

A Kinetic Energy Harvester (KEH) should provide up to 100uW

  1. A conventional KEH is designed for a specific frequency and amplitude.
  2. The vibration frequency and amplitude may change over time or in different working modes.
  3. The changes in frequency and amplitude changes the power conversion efficiency of such KEH.

Schematics of Enervibe’s adjustable KEH for IOT

Feedback from a microcontroller and a vibration sensor allows detection of changes in the frequency and frequency amplitude that are used to adjust the harvester to its peak power conversion.
