A Compact Non-Linear Energy Harvester to an Indirect Wagon Safety Monitoring

This article addresses safety concerns in heavy-haul trains, focusing on the evaluation of derailment propensity without the need for instrumented wheelsets.Based on an innovative approach, which utilises strategically positioned sensors along freight wagons to indirectly measure derailment propensity, thus circumventing the complexities and costs associated with instrumented wheelsets.However, implementing these sensor systems poses challenges, particularly regarding power autonomy.The article emphasizes the potential of vibrational energy harvesting, specifically the OSo-mag structure, as a sustainable power source for these sensors.
