preparation example Construction

[0030] The present invention also provides a preparation method of a wearable flexible sensor, which is characterized in that, comprising the following steps:

[0031] (1) Cloth cleaning. Soak the cloth with a mixed solution of alcohol and acetone with a volume ratio of 1:1, and ultrasonically clean it in an ultrasonic generator for 5-10 minutes. Remove the fabric and blow dry with an air gun.

[0032] (2) Apply the barrier layer. Evenly coat the slurry with a solid powder content of 15%-30% on the surface of the cloth treated in step (1), spin coating at a speed of 500-2000 rpm for 10-30 seconds, and bake .

[0033] (3) Apply the gap filler. Drop the flexible colloidal solution on the substrate in step (2) for uniform spin coating, the spin coating speed is 500-1000 rpm, and the time is 10-30 seconds. The spin-coated samples were baked in an oven. After the baking, the temperature is naturally cooled to room temperature; the spin coating and annealing are repeated repea...

Embodiment 1

[0040] Arrange cotton with a size of 20mm×20mm in a mixed solution of alcohol and acetone with a volume ratio of 1:1 for ultrasonic cleaning for 10 minutes, take out the cloth and blow dry it with an air gun. Lay the cleaned cotton cloth on the middle of the 25mm×25mm Si sheet, and place it on the glue-spinning machine. The silver paste with a solid powder content of 15% was dropped on the surface of the cloth, and spin-coated at a speed of 1000 rpm for 20 seconds. Remove the sample from the Si sheet, remove the tape on the back of the cloth, and bake the sample in an oven at 150°C for 30 minutes. Spread the cloth coated with barrier layer on the middle of the Si sheet again, and place it on the gluing machine. AZ5214 photoresist was dropped on the surface of the barrier layer and rotated at 600 rpm for 20 seconds. The samples were baked in an oven at 100°C for 5 minutes. Repeat the spin coating and annealing process 7 times to get a relatively flat surface. Put the treate...

Abstract

The invention relates to a wearable flexible sensor and a making method thereof, and belongs to the textile material field. The wearable flexible sensor comprises a flexible fabric, a conductive electrode layer and a sensor layer, the surface of the flexible fabric is provided with a barrier layer, a gap filling layer is arranged between the barrier layer and the conductive electrode layer, and the material of the barrier layer is a metal. The wearable omnidirectional-induction skin sensor can be realized on the surface of a cloth having a good permeability, a good flexibility and a good comfortableness through adopting a simple mode, and electronic devices like the wearable flexible sensor can be worn for a long time without influencing normal daily activities.

Description

technical field [0001] The invention belongs to the field of textile materials, and relates to methods for fabric surface treatment and functional coating preparation. Background technique [0002] As the clothing industry moves towards functionalization, intelligence and humanization, clothing is no longer an ordinary product that satisfies people's clothing in the traditional sense, and various high-tech textiles have emerged one after another. Smart textiles that can be combined with medical technology have become a major research direction in the field of high-tech textiles. [0003] In order to meet the needs of human beings for the conquest of harsh environments and the care of special groups of people, the high-tech textile field is committed to manufacturing detectors that can collect human life information, which has led to the birth of clothing sensors. The clothing sensor is based on clothing fabric, and there is a layer of rectangular array on it. The two layers...
