▎ 摘　　要

NOVELTY - The sensor has a flexible substrate which adopts polyimide film. The blood oxygen sensor includes multiple sets of laser direct writing graphene/metal composite electrodes, and light-emitting units and detection units respectively connected to different groups of laser-printed graphene/metal composite electrodes. The temperature sensor adopts group of laser direct writing graphene/metal composite electrodes. The flexible packaging structure is used to package the blood oxygen sensor and the temperature sensor. USE - Fast-printable flexible blood oxygen temperature sensor for monitoring patients. Uses include but are not limited to coronary heart disease, hypertension, hyperlipidemia, cerebral thrombosis and vascular disease, respiratory system disease such as asthma, tracheitis and pulmonary heart disease. ADVANTAGE - The sensor prepares graphene/metal composite electrodes through multiple laser direct writing techniques, which improves the conductivity and temperature sensitivity of the electrodes, and quickly realizes blood oxygen/temperature sensors. The sensor has broad market prospects in the fields of flexible electronics and wearable medical care. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method for fast-printable flexible blood oxygen temperature sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the flexible blood oxygen temperature sensor of fast printing. (Drawing includes non-English language text)
