Problems solved by technology

These flexible sensors can realize multifunctional sensing, but there are still some deficiencies, which are mainly reflected in: 1. The structure is complex, the preparation cycle is long, the cost is high, and it is not suitable for large-scale preparation; 2. The sensing material contains non-degradable components, there is a hidden danger of electronic pollution, which will cause damage to the environment to varying degrees, and does not meet the requirements of green and sustainable development

Abstract

The invention discloses a preparing method of a multifunctional paper-based flexible sensing material. The preparing method comprises the steps of 1, fixing a template to the upper surface of paper, and reserving a hole which is communicated with the outside and is in a preset shape in the template; 2, spraying a prepared conductive material dispersion liquid on the template in step 1 to form a conductive layer with a preset pattern, wherein a conductive material is carbon black or graphene or a mixture of the carbon black and graphene; 3, measuring the resistance value of the conductive layerafter drying; 4, repeating the steps 2 and 3, when the ratio of the difference of the resistance values of the two times to the resistance value of the last time is within 0.2%, removing the templateto obtain the multifunctional paper-based flexible sensing material. After the paper-based flexible sensing material is prepared into a sensor, the strain index in strain sensing is 12-15, and the response time is 0.34-0.4 s; the temperature range of 0-60 DEG C can be detected, the relative humidity of 16-98% can be detected, and the pressure of 0-250 KPa can be detected.
