A tyre monitor is disclosed including a sensor device configured to operate within an enclosed space formed by the wheel and the tyre, and an energy harvester unit. The energy harvester is arranged to convert a first type of energy experienced by the harvester unit in use (e.g. mechanical energy, thermal energy) into electrical energy to energise the sensor device. The energy harvester may be, for example, a piezoelectric device or a thermoelectric generator. In use, mechanical stresses experienced by the tyre monitor are converted into electrical energy which can be used to energise the sensor as a supplement to energy from the battery within the tyre monitor, thus prolonging its service life.
