Problems solved by technology

Reflective blood oxygen sensors currently on the market are mainly composed of substrates, light-emitting diodes with two light-emitting wavelengths, and photoelectric sensors. However, the light-emitting diodes and photoelectric sensors used are rigid components, and the light path will be caused by the deformation of the skin during the test. changes, so that the test accuracy is greatly reduced

Abstract

The invention provides a flexible blood oxygen sensor and a manufacturing method thereof. The flexible blood oxygen sensor includes a flexible substrate, and an infrared light emitter, a red light emitter, and a photodetector are arranged on the flexible substrate. The emitter and the red light emitter are respectively provided with a molecular formula of A X B 1‑x PB y Br 3‑y Infrared light-emitting layer and red light-emitting layer made of organic-inorganic hybrid perovskite materials. The invention provides a flexible blood oxygen sensor, which can better measure the blood oxygen content in the blood.

Description

technical field [0001] The invention relates to the field of blood oxygen sensors, in particular to a flexible blood oxygen sensor and a manufacturing method thereof. Background technique [0002] Wearable blood oxygen sensors can be divided into two types: transmissive and reflective. The theoretical basis is Lambert-Beer’s law. Light of a certain frequency passes through human tissue, then the signal is extracted and analyzed, and finally the blood oxygen in the blood is calculated. saturation. [0003] At present, most blood oxygen sensors are transmissive, but due to the limitation of the transmissive principle, the test can only be limited to thinner parts such as fingertips and earlobes. The reflective blood oxygen sensor is not limited by the position of the test body surface, and the test range is wider. Reflective blood oxygen sensors currently on the market are mainly composed of substrates, light-emitting diodes with two light-emitting wavelengths, and photoelec...
