Abstract
A device for transmission and storage of energy into a mobile data carrier designed in a card-shaped manner, which is insertable into a flute-shaped transmission unit. The transmission unit is designed as a capacitively acting coupling station for energy and information and consists of two flat electrodes spaced from each other, which are embedded into material layers having high dielectric constants. The mobile data carrier also consists of two flat electrodes, arranged in parallel planes with respect to each other, which are coated externally with dielectric material and have therebetween a printed circuit board carrying electronic circuit elements. The mobile data carrier is particularly suitable for application areas involving data acquisition in a motor vehicle branch or in industrial utilization involving rough handling.
