Abstract: A sensor arrangement suitable for determining a condition. A first RFID-unit and a second RFID-unit are subjected to the condition. The second RFID-unit is at least partly provided with a degradation unit having such properties that, when subjected to the condition, the second RFID-unit is functionally degraded to a greater extent than the first RFID-unit. A sensor arrangement product includes at least one sensor arrangement.

Abstract: An RFID antenna is fabricated to operate in three dimensions. An antenna including a first conductive trace and at least one second conductive trace is formed on an unfolded packaging substrate having a first surface and at least one second surface. An integrated circuit is connected across the conductive traces. The unfolded packaging substrate is formed into a three-dimensional package having multiple sides. For example, the unfolded packaging substrate is folded into a cube-shaped container having six sides. The integrated circuit is formed on a first side, while portions of the first and second conductive traces may be formed on both the first side and at least one second side. In this manner, the antenna is three-dimensional and operable to more effectively communicate with a three-dimensional electromagnetic field.
