Abstract

The invention provides a self-powered respiratory gas sensor array and a preparation method thereof. The sensor array includes a rotating shaft, a polymer rotor, a polymer stator, a metal receiving electrode, a gas-sensitive film, an air inlet, an air outlet, a lead wire, and a gas kinetic energy collection chamber. , Gas test chamber, the present invention uses real-time and uninterrupted human respiration as an energy source for gas diagnosis, and converts the kinetic energy of human respiration airflow into electrical energy through self-powered technology, so as to continuously supply power to the back-end gas sensor, which can Realize 24-hour all-weather independent respirator real-time self-supply monitoring and guarantee, without external power supply and battery, very suitable for human physiological monitoring and large-scale disease screening in remote areas or underdeveloped areas, completely based on energy harvesting of polymer materials —The transmission mechanism and method simplifies the device structure and integration process, and further improves the compatibility between the energy module and the sensor array.

Description

technical field [0001] The invention relates to the fields of energy collection technology, micro-electro-mechanical systems (MEMS), and electronic polymer sensitive materials, in particular to a self-powered respiratory gas sensor array and a preparation method thereof. Background technique [0002] As the most important life activity of human beings, respiration is the process of gas exchange between human and the external environment, including both the gas exchange between the human body and the outside world, and the transportation and exchange of gases in the body. have a close relationship. Pathological surveys and studies of modern medicine have shown that human exhaled breath contains rich physiological and disease marker information, and many components can be used as "biomarkers" for diseases and metabolic processes; therefore, they can be passed through the human body. The detection of certain labeled gas components in respiratory gas is used to monitor human ph...
