This contribution assesses the possibilities of application of Energy Harvesting technology in the field of machine tool diagnostics. These machines are on various parts more often fixed with many sensors monitoring status values such as deformations or temperature. However, in poorly accessible construction nodes, there is a problem with installation of both power and data cables. It could be solved by suitable application of an energy harvesting generator that would provide power supply to a specific sensor and enable wireless transfer of the measured data. In order to test the applicability of this solution, a detailed measurement and analysis of vibrations generated at defined regimes of a machine were performed, both without machining and during power machining with the use of a demonstrator. The results confirmed the possibility to use the technology of Energy Harvesting to capture electric energy from vibrations. Although the demonstrator generated only very little power, with the use of modern communication technology it would be sufficient for selected applications with discontinuous reading of the measured characteristics.
