Abstract
A disposable and wireless sensor system and method are disclosed. In general, a pressure diaphragm can be connected to one or more reusable Surface Acoustic Wave (SAW) probe heads, which are associated with an antenna for wirelessly receiving or transmitting signals that excite the reusable SAW probe head only when the reusable SAW head is in contact with the pressure diaphragm. Interrogation electronics can also be provided, which are associated with the reusable SAW probe head. One or more signals can be wirelessly transmitted to the interrogation electronics for exciting the reusable SAW probe head for pressure sensing applications thereof.
