A touch sensing apparatus includes at least one conductive sensing element and a reading device. The conductive sensing element includes a substrate and a conductive sensing layer. The conductive sensing layer is disposed on at least one surface of the substrate. The conductive sensing layer includes a plurality of conductive sensing units and a plurality of transparent conductive wires. An orientation distribution of the conductive sensing units is by a coordinate encoding method to constitute a coding pattern. The coding pattern includes coordinate information. The reading device is actuated on the conductive sensing layer, senses and decodes the coding pattern to analyze the coordinate information. The touch sensing apparatus can perform a digital writing and recording without power supply.
