Never replace batteries
Switches at DB are monitored with the aid of battery-operated sensors to ensure safe operation and to minimize failures. The Swedish start-up ReVibeEnergy offers a long-lasting, sustainable and cost-effective power source by converting vibrations into electrical energy. The vibrations generated by the rolling wheels of the moving train on the track convert the innovative solution of the Swedish founders into direct current. The transducers can be mounted directly on the vibration source and can be operated for 10 years without maintenance. The low current generated in this way is used to supply energy continuously to sensors. Batteries whose load condition is regularly checked by maintenance personnel and which have to be changed at regular intervals are no longer necessary.
