Abstract

The invention relates to a breathable nano-sensor array detecting device and method. The device comprises a low impedance sensing module, a high impedance sensing module, an embedded processor and a wireless communication module. The embedded processor is respectively connected to a low impedance breathable nano-sensor array and a high impedance breathable nano-sensor array through the low impedance sensing module and the high impedance sensing module. The embedded processor is connected to the wireless communication module. Through the gas adsorption action, resistance change is produced through a special surface area and a porous nanostructure. The breathable nano-sensor array detecting device is combined with intelligent hardware to form a sensor data processing and transmission terminal, can analyze human exhaled gas, is connected to a portable device through a wireless interface and provides real-time continuous monitoring.

Description

technical field [0001] The present invention relates to the fields related to health detection and disease diagnosis of exhaled gas by nano-alloy sensor, in particular to an exhalation nano-sensing array detection device and its implementation method, which are used to detect the response of human exhaled gas in the nano-alloy sensor array, and can be used to judge certain Early warning of the risks of certain diseases. Background technique [0002] The compounds exhaled by each person are unique and can reflect the metabolic and pathological conditions of the body. It has been shown that diseases can be diagnosed based on these compounds. Exhaled breath detection has the advantages of non-invasive, non-invasive, and convenient sampling. It is expected to become a high-throughput disease screening tool and can be used for clinical big data sample analysis. Moreover, the accumulation of low-cost, high-throughput, and large-sample data is conducive to the discovery of new dis...
