Design method of soft sensing materials for soft sensing material pressure sensor

Abstract

The invention relates to a design method of soft sensing materials for a soft sensing material pressure sensor. According to the design method, the soft sensing materials mixed with tiny structure bodies are deformed when being affected by the outside, the electrical characteristics are changed, the relevant electric signal variation caused by the variation of relevant positions inside a tiny space inside soft materials generated by outside effect is detected out to be used as pressure signals which cause deformation of the soft materials. According to the design method of the soft materials, the soft materials mixed with the tiny structure bodies are used as the sensing materials of the pressure sensor. Conductive tiny spiral-shaped structures are mixed in the soft rubber materials, or soft rubber materials with structure bodies of an elastic opening-closing structure are made to the soft sensing materials. When the shapes of the mixing materials are changed, the mutual positions inside the tiny space caused by changing of the shapes are changed, and the electric characteristics of the soft materials caused by the variation of stress are changed. Electrical signal variation detected by a detecting method is used as the application as the application method of the materials of pressure signals.

Description

Technical field [0001] The present invention relates to the use of a soft induction material mixed with a microstructure when it is deformed by the outside influence and its electrical characteristics change, and the relative position of the soft material in the small space inside the soft material that occurs under the external influence is changed. The related electrical signal change caused by the detection is used as the design method of the soft sensing material used in the pressure sensor that causes the deformation of the soft material. Background technique [0002] Existing pressure sensors include strain sensors that detect strain after the membrane is deformed, and are widely used in various industrial and civil fields. The above sensors are basically hard materials as materials or mechanisms for sensing speed signals. There is no flexible polymer material like rubber as a pressure signal sensing material and a simple pressure sensor. Summary of the invention [0003] ...
