Abstract

This invention provides a touch sensing apparatus, comprising a signal source, a conductor, a sensor, a rectifier, and a detector. The signal source is for generating a alternating current signal. A conductor is connected to the signal source. The sensor is for receiving the noise of the user, and constitutes a capacitance with the conductor. The rectifier circuit is for rectifying the alternate current from the signal resource into a negative direct current resource with the noise generated synchronously. The negative direct current is used as negative resource of the detector. The detector is connected with the sensor and is for receiving the signal transmitted from the sensor. The apparatus could improve the sensitivity of sensing the noise of the body and the simple of the circuit could degrade the cost.
