Saw sensor module

A SAW sensor module, comprising:

• a cartridge having a sensor chip of piezoelectric material, said cartridge having at least one SAW sensor formed on said sensor chip, said cartridge having cartridge coupling electrodes, and said cartridge including at least one alignment element being at least one of metallic or magnetic;
• said at least one SAW sensor having sensor electrodes;
• at least one control and reading device for said least one SAW sensor, said at least one control and reading device including a device board having a device board front side;
• a device connection formed on said device board;
• device coupling electrodes formed on said device board front side;
• electrical conductors passing through said device board and connecting said device coupling electrodes to said device connection;
• said cartridge coupling electrodes being capacitively coupled to said device coupling electrodes and to said sensor electrodes;
• and
• at least one magnetic element formed on said device board, said at least one alignment element aligning with said at least one magnetic element.
