The invention discloses a three-dimensional flexible touch sensor and a decoupling method thereof. The sensor comprises three layers of insulated wires which are parallel layer by layer, wherein the second layer of insulated wires (3) and the third layer of insulated wires (5) in the wires are vertical to and parallel with the first layer of insulated wires (1) respectively; a plurality of electrodes of the corresponding layer are electrically connected to each layer of wires at equal intervals respectively; the projection of each electrode (2) of a first layer is positioned in the centre of a square formed by four electrodes (4) of a second layer and in the centre of a square formed by four electrodes (6) of a third layer at the same time; and a conducting rubber (7) is arranged between each layer of insulated wires and each layer of electrodes. The method comprises a step of obtaining resistance value changes between each row of the first layer and each column of the second layer, and between each row of th
