FINE MATERIAL SENSING DEVICE, CAPABLE OF OBTAINING EXACT MEASUREMENT RESULT USING AN ELECTRICAL MEASUREMENT MODE

摘要

PURPOSE: A fine material sensing device is provided to accurately detect fine materials by applying electric signals and sensing fine materials.;CONSTITUTION: A fine material sensing device comprises a variable power part(100), a first electrode(110), and a second electrode(120). The variable power part outputs the varied electric signals. The first electrode connects to an AC power supply unit. The second electrode comprises an upper electrode(121), a lower electrode(123), and a piezoelectric(125). The piezoelectric is positioned on the upper electrode and the lower electrode.;COPYRIGHT KIPO 2010
