System for transmitting and/or collecting information

摘要

The system (1) has a component (3) located opposite to a rotor (2), and an active component (5) e.g. actuator or sensor, attached to the rotor. The active component is formed for collecting and/or transmitting information, and a photo-sensitive energy receiver (9) e.g. photovoltaic cell, is attached to the rotor for changing light energy into electrical energy. The receiver is connected to the active component for electrical energy supply, and an energy light source (8) e.g. photoactive layer or LED, is attached to the component (3) for irradiating the receiver.
