Abstract

The invention belongs to the technical field of wearable sensors, and particularly relates to a full-silk-fibroin-based conductive gel sensor and a preparation method thereof. According to the preparation method, firstly, carbonized silk fibers with good dispersing performance and high conductivity are prepared through a gradient carbonization procedure, and then the conductive full-silk-fibroin-based gel is prepared by combining the carbonized silk fibers and degummed silk fibers; the preparation process is rapid and efficient, prepared gel is stable in performance, and large-scale preparation can be carried out; and the novel silk protein gel sensor is obtained through sandwich type packaging of a VHB adhesive tape. The silk protein gel sensor can be used for realizing temperature sensing, electrocardiosignal measurement and auxiliary braille recognition, and shows excellent stability, safety, accuracy and high efficiency. The silk protein gel sensor can also be used for individual health monitoring to realize contact perception and non-contact perception, and is expected to become a next-generation wearable flexible electronic product.
