A tactile sensing system having a sensor component which comprises a plurality of layers stacked along a normal axis Z and a detection unit electrically connected to the sensor component, wherein the sensor component comprises a first layer, designed as a piezoresistive layer, a third layer, designed as a conductive layer which is electrically connected to the detection unit, and a second layer, designed as a spacing layer between the first layer and the third layer, wherein the first layer comprises a plurality of electrodes In electrically connected to the detection unit, wherein at least one contact force along the normal axis Z on the sensor component is detectable by the detection unit due to a change of a current distribution between the first layer and the third layer, wherein at least one lateral strain on the sensor component is detectable by the detection unit due to a change of the resistance distribution change in the piezoresistive first layer.
