1. A sensor system, comprising:
- a sensor element for measuring a physical parameter;
a transponder for transmitting the measured physical parameter to a read device; and
a capacitive coupling, including a first pair of plates connected to the sensor and a second pair of plates connected to the transponder, for wirelessly linking the sensor element to the transponder, the first and second pair of plates separated by a fixed distance.

Abstract
The invention relates to the coupling of a sensor element to a transponder, the connection of said sensor element to the transponder being achieved by capacitive or inductive coupling. This enables any separation layer that may lie between the sensor element and the transponder to be retained, allowing the invention to be advantageously used in gas and liquid-tight containers, such as tires. In addition, electrically non-conductive materials of the object to be measured can be used as a dielectric for the capacitive coupling and electrically conductive parts can form part of a conductor loop for the inductive coupling.
