A monitoring system monitors a presence or condition of a particular fluid in a device for storing or conducting the fluid using permittivity properties of the fluid. The system includes: the device for storing or conducting the fluid; a detector component being an integral part of the device and having a component body and a passive antenna deposited on a surface of the component body; and a reader device having a reader antenna. The reader device emits an electromagnetic output signal with a predefined output power and over a predefined frequency range via the reader antenna to the passive antenna and measures a reflected signal over the predefined frequency range, which is reflected from the passive antenna. The reader device also compares the reflected signal with at least one reference signal of at least one reference fluid to determine the presence or the condition of the particular fluid.

An elastomeric sensor component includes a component body made of elastomer material and a sensor module embedded within the component body. The sensor module includes a sensor chip, a radiofrequency transponder chip electrically connected to the sensor chip, and a loop antenna electrically connected to the radiofrequency transponder chip. The elastomeric sensor component further includes a booster antenna having a booster antenna loop, with the booster antenna loop deposited on a surface of the component body in order to allow near field data communication and energy transfer with the loop antenna.
