Abstract
A material identifying system includes an identifying panel, a voltage source and a determining circuit. The voltage source is arranged to transmit a voltage signal to an object to be identified via the identifying panel in order to obtain an impedance of the object, wherein the voltage source adjusts a frequency of the voltage signal in a predetermined range to find a specific frequency in the predetermined range where the impedance of the object is minimum. The determining circuit is arranged to determine if the specific frequency of the object to be identified matches any specific frequency of a plurality of known materials in order to identify a material of the object.
