Perpetuum Limited

Key technical challenges include overcoming the space constraints and the vibration and shock environment on Locomotive bogies. A smaller lighter vibration energy harvester takes less space but the problem with smaller proof masses is that they are intrinsically less powerful. Therefore, a significant challenge has been to achieve more power per unit mass...

Currently train axle inspections are required on every axle, every year. This is because an axle failure can lead to a derailment and significant damage. Train axle failures have caused major loss of life, with a consequential increase in both non-destructive testing and manual inspection that is expensive and disruptive to efficient rolling stock mainten...

The existing Perpetuum train sensor system uses vibration energy harvesters (VEH) to power a vibration sensor, electronics and communications that can monitor the health of bearings, wheels and the track. It records vibration data and transmits wirelessly via a data concentrator that transmits off the train using the GSM network. The system performs very ...

ENERGYMAN will expand the technical and commercial benefits of Vibration Energy Harvesting by developing novel power management systems that extract significantly more of the available power from both industrial narrow band and rail broadband vibration harvesting. This will be integrated with the development of hybrid energy storage systems that will meet...
