Flexible sensing array with isotropy

The invention discloses a flexible sensing array with isotropy, which comprises a flexible substrate, a plurality of pressure sensing units and a plurality of strain sensing units, and is characterized in that each strain sensing unit comprises a basic sensing unit capable of showing isotropy in a 30-degree range, the basic sensing units are symmetrically arranged to form a symmetrical sensing unit, and the symmetrical sensing units are arranged on the flexible substrate. Strain sensing units are arranged on side lines of a cellular structure showing sextuple symmetry, the cellular structure is subjected to circumferential array to form an isotropic sensing array within the range of 360 degrees, pressure sensing units are integrated at nodes of the sensing array, and the pressure sensing units are in a regular hexagon shape and are connected with the strain sensing units on the periphery through conductive circuits. Six metal electrodes are led out from the six outermost pressure sensing units through liquid
