Abstract

The invention provides a preparation method of a flexible man-machine interaction bionic fabric, which is characterized in that commercial filature silk is used as a matrix, a conductive nanocellulosehybrid material is used as a conductive coating layer, and a polyvinyl alcohol (PVA) film is used as an insulating protective layer for assembling to obtain conductive fibers with a core-sheath structure; then the conductive fibers are woven into a fabric by selecting a weaving or knitting mode according to the requirement on sensing signal capturing precision; and finally the conductive fabric is acquired. The material has biocompatibility and conductivity, also has excellent stability, toughness and self-healing property, can be used for positioning and monitoring motion, and has a wide application prospect in the fields of bioelectronic sensors, wearable electronic equipment, man-machine interaction and the like.

Description

technical field [0001] The invention relates to a method for preparing a conductive fabric, in particular to a method for preparing a flexible bionic fabric capable of man-machine interaction, and belongs to the field of bionic sensor fabric preparation. Background technique [0002] In recent years, flexible wearable electronic devices have flourished and have great application potential in human motion monitoring, health tracking, and wearable communication devices. The core of flexible and wearable electronic devices is flexible and wearable strain sensors. Excellent strain sensors need to meet two characteristics at the same time: large strain range and high sensitivity. Flexible polymers have good flexibility and a large strain range, so they are widely used in the preparation of flexible wearable electronic devices as support materials. Nanomaterials such as carbon nanotubes and graphene are generally used as sensing materials for sensors. However, the currently used...
