Sensing circuit, processing method of sensing circuit and curved surface profile measuring method thereof

A processing method of a sensing circuit, comprising:

• forming the sensing circuit having a matrix circuit and a plurality of circuit substrates, wherein the matrix circuit comprises a plurality of X electrodes and a plurality of Y electrodes, each of the plurality of X electrodes and the plurality of Y electrodes is formed in a zig-zag shape, and arranged in a crisscross manner;
• each neighbouring X electrode pair and neighbouring Y electrode pair comprises a plurality of flexible protection bodies;
• and the plurality of X electrodes and the plurality of Y electrodes are uniformly distributed in the flexible protection bodies in a braiding manner, and the plurality of circuit substrates attaches the matrix circuit to a surface of related safety equipment;
• performing insulation treatment to the sensing circuit;
• and
• guiding an output of the sensing circuit from edges of the plurality of circuit substrates via a lead.
