A pressure-induced counter includes a pressure acquisition unit, a delay unit and a counter unit. The pressure acquisition unit is electrically coupled to the counter unit via the delay unit. The pressure acquisition unit is configured for acquiring a pressure signal of an external pressure applied thereon to generate and output an original electrical signal corresponding to the pressure signal. The delay unit is configured for processing the original electrical signal outputted from the pressure acquisition unit to obtain a processed electrical signal by depressing the leading-edge jitter existing therein. The counter unit is configured for receiving the processed electrical signal transmitted from the delay unit and taking count of the received signals.
