Abstract
A the rotor for a wind energy turbine includes a hub and at least one rotor blade connected to the hub. The rotor also includes comprises at least one sensor for sensing at least one physical value of the rotor, e.g. mechanical stress, and a power supply for supplying electrical power to the at least one sensor. The power supply includes an electromechanical converter for converting mechanical energy from vibrations of the rotor when subjected to wind loads, e.g. during operation of the wind energy turbine, into electrical energy for supplying to the at least one sensor.
