Description

technical field

[0001] The invention relates to the technical field of sensors, in particular to a flexible composite sensor based on silk protein and a preparation method thereof. Background technique

[0002] With the advent of the era of intelligence, the development and combination of material science and smart electronics has triggered a huge change in the field of smart wearables, whether it is used to sense changes in the human body (such as body temperature, heart rate, breathing, etc.), or to use In order to help the human body perceive changes in the external environment, many requirements have been placed on the current wearable devices.

[0003] In order to adapt to wearable devices, more and more flexible sensors have been designed in recent years, and many sensors have the advantages of high precision and high sensitivity. Although many excellent sensors with a single function have been reported, the performance of composite sensors is generally limited by fac...
