“…Currently, many diagnoses are carried out on the bogies of railway units, for example, monitoring the train speed, 2 anti-slip skid re-adhesion control 3 , the measurement of the temperature profile of critical parts, 4 rail lubrication analysis, 5 and detection of faults in the engine valve, 6 among others. The demands on these sensors are significant because there is an increasing trend to monitor many characteristics of the units.…”

The goal of the research presented in this paper is to design and incorporate new technologies into railway bogie-mounted sensors. It is often impossible to connect the mounted systems to physical wires due to their location in an inaccessible position or the distance to the energy source. Therefore, another power source must be used to solve this problem. Energy harvesting technology is an increasingly popular solution that extracts energy from the ambient environment and transforms it into electrical energy. Using piezoelectric transducers, it is possible to transform the vibrations experienced by the bogie into energy that can be used to power the sensors. A prototype with multiple piezoelectric transducers has been designed, built and subjected to tests to validate the technology. The experimental results for all of the different configurations tested and levels of energy collected are presented.
