| Abstract |
Indirect Touch switch which detects the change of capacitance around the electrode of QT113H chip from QPROX is designed and assembled. Sensitivity analysis of dielectric materials which prevents electrodes from direct touch is performed and the results are displayed in tables and graphs. Glass, acryl, and MDF is used to insulate the electrode and to measure the operating sensitivity of indirect touch switch. While the difference of permittivity of the dielectric materials are large, it is confirmed that the operating sensitivity of each dielectric materials are not so large as the differences of those of dielectric materials. |
