Abstract
Provided is a multiple SAW sensor system capable of sensing a plurality of target materials in the SAW sensor with a single detector by using a multiplexer. According to the multiple SAW sensor system, the target materials in SAW sensors may be sensed with a single detector, thereby avoiding unnecessary power loss. Also, a plurality of target materials in a sample may be sensed, thereby reducing a waste of the sample.
Claims7
A multiple surface acoustic wave sensor system, the system comprising:
- surface acoustic wave sensors;
- a oscillator or a signal generator connected to input parts of the SAW sensors;
- a first multiplexer connected to input parts of the surface acoustic wave sensors, which selects one of the sensors;
- a second multiplexer connected to output parts of the surface acoustic wave sensors, which selects one of outputted electrical signals;
- and
- a detector which senses the selected electrical signal by the multiplexer.
