the reference RC oscillator 1 is 10Hz, RC oscillator 2 (= Sensor 1) is not oscillating, which corresponds to “Dry” (= no urination), and RC oscillator 3 (= Sensor 2) is 5Hz, which corresponds to “Wet” (= urination). Figure 30.3.3(d) shows a successful toggle operation of the multiplexer.

The RC oscillator converts the resistance between electrodes (RMEA) to the frequency of OSC. Fig. 30.3.4 (b) shows the measured waveform of OSC. Figure 30.3.4(c) shows the measured dependence of the oscillation period on RMEA. In this work, the target range of RMEA is from 2MΩ to 10MΩ because RMEA in cotton immersed in normal saline is several megaohms.
