Graphene-based attached skin sensor preparation method

Abstract

The invention relates to a graphene-based attached skin sensor preparation method, and belongs to the technical field of human body detection. The invention comprises the steps that a graphene oxide solution is adopted for conducting dropwise coating or spin-coating on water transfer paper, a graphene oxide layer is formed on the water transfer paper, a laser irradiation method is adopted, the graphene oxide layer is reduced to be a graphene sensing layer which is put into water, a sacrificial layer on the lower portion of the graphene sensing layer and a dry graphene oxide layer not subjectedto laser irradiation fall off, a flexible substrate layer is left, a conductive material is arranged at the end of the graphene sensing layer, and the attached graphene skin sensor is obtained. According to the prepared skin sensor, for the graphene sensing layer, the pattern of graphene can be designed individually, the shape and size can be adjusted as needed, simplicity and attractiveness areachieved. The prepared skin sensor can be attached to the skin vibration part easily, and daily portable sensing is conducted.

Description

technical field [0001] The invention relates to a preparation method of a graphene-based adhesive skin sensor, which belongs to the technical field of human body detection. Background technique [0002] Movement of the skin surface can characterize many physiological activities. For example, the undulation and stretching of the chest skin or abdominal skin caused by human breathing can be used to represent the breathing frequency and volume of the human body; the vibration of the skin at the heart can also represent information such as heartbeat and heart rate; the skin at the throat of the human body Vibration information can represent neck movements such as human speaking, vocal cord vibration, swallowing, and head turning; skin vibration information at the human wrist can represent pulse pulse, wrist rotation and other information. [0003] In terms of respiration detection, most of the wearable respiration monitoring devices on the market use ceramic capacitance or cera...
