Description

technical field [0001] The invention relates to the fields of energy collection technology, micro-electromechanical systems and breath monitoring, in particular to a bionic shell-type breath monitoring friction nanogenerator and a preparation method thereof. Background technique [0002] As an important physiological process of the human body, respiration is one of the most basic physiological indicators to measure the vital signs of the human body. Due to the advantages of continuous, non-invasive, comfortable and humanized respiratory diagnosis, respiration monitoring is very important in human health management or early disease screening. There have been preliminary studies in many research fields such as Cha. Usually, the real-time monitoring of human vital signs can be realized by real-time monitoring of changes in the electrical signal output by the sensor under different breathing behaviors. However, the traditional respiration sensor's dependence on external power s...
