A carbon brush (11) for use in a sliding contact in a dynamoelectric machine, comprises a brush body (111), formed of an electrically conducting low friction material, the brush body having a contact surface for providing said sliding contact, a brush sensor (113), for detecting at least one parameter relating to the carbon brush, first and second electrical connections (41, 42), which are spaced apart along a current path through said carbon brush (11), such that a voltage drop is present between said first and second electrical connections (41, 42) when a current is conducted through said carbon brush (11), and an energy harvesting device (4) configured to act as a power source, by utilizing the current and the voltage drop. for providing electrical energy for driving said brush sensor (113). The energy harvesting device (4) is electrically connected to said first and second electrical connections (41, 42). There is disclosed a system comprising such carbon brush and a method of supplying power to a brush sensor.
