TYRE PUNCTURE DETECTION SYSTEM

A tyre puncture detection system (3) is provided that comprises a sensor (4) for integrating into the tyre (1), a sensing system (5) and an inductance measuring circuit (13). The sensor (4) comprises a first conductive layer (6), a second conductive layer (7) and an insulating layer (8) arranged in the tyre (1), the insulating layer (8) being arranged between and electrically isolating the first conductive layer (6) and the second conductive layer (7) from one another. The sensing system (5) comprises a transformer configuration having a primary winding and a secondary winding, wherein the primary winding is provided by a first coil (12) having a first inductance and the secondary winding is provided by a second coil (9) having a second inductance, the second coil (9) being connectable to the sensor (4) and being sized and shaped to be arranged on an inner surface of the tyre. The first coil (12) is magnetically coupled to the second coil (9). The inductance measuring circuit (13) is coupled to the second coil (12). The inductance measuring circuit (13) is configured to measure a change in the inductance of the first coil (12) caused by a change in an inductance of the second coil (9) that is caused by a puncture in the tyre (1).
