Sensing device and sensing method are disclosed. The multi-dimensional force sensing device includes a soft laminose dielectric structure, a conductive sheet, at least one first electrode sheet, at least one second electrode sheet, a measuring unit and an analysis unit. The soft laminose dielectric structure has a first surface and a second surface opposite to each other. The conductive sheet is disposed on the first surface and has a vertical projection area. The first electrode sheet is disposed on the second surface and totally in the range of the vertical projection area. The second electrode sheet is disposed on the second surface and partially in the range of the vertical projection area. The analysis unit analyzes the magnitude and direction of a force applied on the conductive sheet according to the capacitance between the at least one first electrode sheet and between the first and the second electrode sheets.
