Abstract

The invention discloses a photoelectric integrated sensing chip-based acetone detection device and a preparation method, the photoelectric integrated sensing chip-based acetone detection device comprises an electroluminescent device and an acetone sensitive layer, the electroluminescent device and the acetone sensitive layer are cube-shaped, the acetone sensitive layer is distributed on the upper end surface of the electroluminescent device, the lower end face of the acetone sensitive layer is attached to and fixedly connected with the upper end face of the electroluminescent device; the acetone sensitive layer is a zinc oxide nano array; and sensitive film leads are arranged on the acetone sensitive film and the electroluminescent device. The sensor obtained by integrating the electroluminescent sheet and the acetone-sensitive zinc oxide nano array can realize high-selectivity response to acetone on one hand, and integrates the luminescent device and the acetone-sensitive layer on the other hand, so that the power consumption of the sensor is effectively reduced, and low-power-consumption detection of acetone in a human respiration sample is realized.

Description

technical field [0001] The invention relates to the field of acetone detection, in particular to an acetone detection device and a preparation method based on a photoelectric integrated sensor chip. Background technique [0002] Diabetes can induce severe cardiovascular disease and accelerate the rate of deterioration of renal function. The morbidity rate, disability rate and mortality rate of diabetes, as well as the degree of harm to human health, have ranked third among chronic non-communicable diseases. The death caused by it is also the fifth leading cause of death in the world today. Early detection of diabetes will help to give patients more effective treatment. At present, the detection of diabetes mainly relies on blood tests, which cannot realize the early detection of hidden dangers of the disease. [0003] The researchers found that the concentration of acetone in the exhaled breath of the human body can indirectly reflect its physical condition. Studies have...
