Apparatus and method for state detection

An apparatus for state detection, comprising:

• one or more charge sensing elements arranged on a terminal;
• a charge collection circuit connected to the charge sensing element;
• and
• a state detection module connected to the charge collection circuit;
• wherein, the charge sensing element is configured to radiate charge generated by the charge collection circuit, and transmit reflected charge to the charge collection circuit;
• the charge collection circuit is configured to generate charge and radiate the charge out through the charge sensing element, and collect the reflected charge from each of the charge sensing elements to generate an induced charge value of the charge sensing element, and output the induced charge value of each of the charge sensing elements to the state detection module;
• the state detection module is configured to determine a state of the terminal according to the induced charge value.
