摘要

System for supplying a number of sensors and actuators comprises a resonance circuit (9) having two spatially distributed coils (2, 5) to supply devices arranged in a screened volume region. The first coil (2) is positioned as a receiver coil in the magnetic field (1) and the second coil (5) is positioned as emitter coil in the screened volume region. The two coils are joined together by a connecting line (3). The whole system is coordinated with the resonance with the inclusion of a resonance capacitor (6). The local magnetic field produced by the second coil supplies the devices arranged in a screened volume region. Preferred Features: The connecting line is a coaxial line. An air coil is used as the first and second coils.
