The relative area of B electrodes changes, and the variation of capacitance is also identical with the variation tendency of the relative area, and signal
Source also changes to B electrodes by A electrodes, therefore is present with the capacitance variations curve shown in Fig. 7-2, with the extension of time, A is electric
The capacitance of pole is gradually reduced, and the capacitance of B electrodes gradually increases, therefore, for the induction electrode of the structure, when capacitance variations curve
When as shown in Fig. 7-2, it is judged as slide.
Fig. 8-1 shows the induction electrode 222 of another structure, when finger slides into B electrodes from A electrodes, finger and A electrodes
