PROBLEM TO BE SOLVED: To provide a sensor system for sanitary capable of detecting the soiling of sanitary goods such as diaper or urine absorbing pad. SOLUTION: A sheet-shaped LC resonance tag 5 formed of a coil pattern and a capacitor pattern is embedded inside the sanitary goods such as urine absorbing pad 6. A flexible antenna 4 is connected to a reflected wave scanner 1 provided with a transmitter and a receiver for detecting the resonance frequency of the LC resonance tag by comparing a transmitted waveform with a received waveform. The urine absorbing pad 6 is mounted inside underwear, the flexible antenna 4 is mounted on the surface of underwear, and the reflected wave scanner 1 is stored in the pocket or the like. When the urine absorbing pad 6 gets wet, the received waveform is changed by a change in the resonance frequency characteristics of the LC resonance tag 5 in contact with the liner of the pad, the vibrator of the reflected wave scanner 1 is driven and a user can know the incontinence of urine without being noticed by anyone. |
