The invention discloses a grid
pressure sensing chip and a preparation method thereof, and a pressure distribution sensor. The grid
pressure sensing chip comprises an insulating bottom layer, an upper layer, and a row and a column
electrode configuration layer arranged between the insulating bottom layer and the upper layer, wherein a plurality of row electrodes are arranged in the row
electrode configuration layer; a plurality of column electrodes are arranged in the column
electrode configuration layer to form a grid distribution together with the row electrodes; an intermediate layer is arranged between the row and the column electrode configuration
layers; a plurality of
pressure sensitive bodies are arranged in the intermediate layer just at the cross points of the row and the column electrodes; each
pressure sensitive body is respectively connected with one row electrode and one column electrodes at two end faces thereof; and the insulating bottom layer, the upper layer, the row and the column electrode configuration layer and the intermediate layer integrally form a rectangular sheet. The pressure distribution sensor comprises a frame, a plurality of grid
pressure sensing chip spliced in the frame, and electrode connection structures arranged on inner two sides of the frame. The inventive grid pressure sensing chip and the sensor can conveniently detect the pressure distribution on a local contact surface.
