<P>PROBLEM TO BE SOLVED: To provide a wireless sensor system that can discriminate each passive sensor individually and can be miniaturized. <P>SOLUTION: A master unit 20 transmits an excitation signal to a passive sensor 10. The passive sensor 10 generates a resonance signal at a resonance frequency fp caused by the excitation signal according to a physical quantity T to be detected, and transmits the resonance signal to the master unit 20. A related information recording medium 30A including a bar code is recorded with related information such as a discrimination ID of the passive sensor 10 and a patient discrimination ID. The master unit 20 performs measurement processing and reads a related information recording medium 40 with a related information reading unit 26 to obtain related information. The master unit 20 uses the resonance signal to calculate a physical quantity, associates the physical quantity with the related information, and displays the physical quantity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
