Abstract
The invention relates to a system (1) for monitoring a conductivity in a volume. The system according to the invention is suited to be used for industrial and medical applications. The system (1) comprises a resonant circuit (2,4,10) comprising a conductive coil (4) driven by a power supply means (8), said conductive coil being arranged to induce an oscillating magnetic field in the volume. The power supply means (8) is arranged to measure a power loss of said resonant circuit due to the conductivity in the volume. The conductive coil (4) is arranged to be integrated into an insulating fabric (9). Preferably the conductor forming the conductive coil is interwoven with threads of fabric. For medical applications it is preferable that the system is integrated into a bodywear, for example a T-shirt.
