Abstract

The invention discloses a wearable flexible temperature sensor for monitoring human body temperature and a preparation method thereof, which has a sandwich structure composed of an adhesive bandage-intermediate temperature-sensitive layer-flexible gas-permeable film, wherein the intermediate temperature-sensitive layer is It is obtained by film formation with polyvinylidene fluoride as the matrix, polyethylene glycol as the temperature sensitive material, and graphite powder as the conductive filler. The flexible temperature sensor of the invention has high sensitivity, good detection effect, good wearability, good flexibility, and good air permeability.

Description

technical field [0001] The invention belongs to the field of flexible temperature sensors, and in particular relates to a wearable flexible temperature sensor with a sandwich structure that is breathable and a preparation method thereof, which are used for monitoring human body temperature. Background technique [0002] Body temperature is one of the most important physiological parameters in physiology. It is closely related to the chemical reactions in the physiological system. It is an important indicator for judging human health and disease, and is often the basis for deciding whether to start treatment. Accurate measurement of local temperature changes in soft tissues (whether large-scale motion or not) is crucial for understanding thermal phenomena of body temperature balance, assessing complex health conditions, and further providing the possibility to construct smart medical and medical systems. Therefore, the accurate detection and recording of the body temperature ...
