A sensor system comprising a tag. The tag comprises at least one radio-frequency chip, a first antenna disposed in electrical communication with the chip and a non-conductive coating disposed upon a surface of the tag. The chip comprises a memory element providing electrical storage of a binary coded word comprising at least one bit and output terminals. The antenna is in electrical communication with the output terminals. The non-conductive coating covers the chip and defines a perimeter. The perimeter is disposed over and exposes a portion of the antenna.
