1. A sensing method of a sensing device, wherein the sensing device comprises a stretchable sensing device, wherein the stretchable sensing device comprises a first substrate, a first sensing element layer and a stretchable material layer, the first substrate has a plurality of first slits, each of the first slits penetrates through the first substrate from top to bottom to divide the first substrate into a plurality of first distribution regions, the first sensing element layer comprises a plurality of first sensing electrodes, the first sensing electrodes are located within the first distribution regions, a first horizontal spacing between at least two of the first sensing electrodes respectively located within two adjacent first distribution regions is greater than a second horizontal spacing of the two adjacent first distribution regions, the first horizontal spacing is in the same plane as the first sensing electrodes, the second horizontal spacing is in the same plane as the first distribution regions, the first horizontal spacing is on top of and overlapping the second horizontal spacing, the stretchable material layer fills the first slits between each adjacent two of the first distribution regions to cause the first horizontal spacing and the second horizontal spacing changeable, and the first sensing electrodes are meanderingly distributed along outer edges of each of the first slits, wherein the sensing method comprises:

  • reading an electrical signal from one of the first sensing electrodes to obtain a first signal value corresponding to the one of the first sensing electrodes; and

    determining a deformation state of the stretchable sensing device from a variation of the first signal value.
