Research on micro/nano ionization sensor for detecting harmful gases
In order to effectively prevent the excessive concentration of harmful gases from causing dam-age to economic benefits and the safety of human life and property,a new detection method has been pro-posed and designed.Through a series of tests on micro/nano ionizing sensors,the designed sensor exhib-its strong bending resistance and fast response recovery ability.Multiple concentrations of benzene and toluene gases are tested under experimental conditions of room temperature,atmospheric pressure,and relative humidity of 75％.Corresponding recognition models are constructed based on the intensity of characteristic noise to identify the concentration of the gas.The experimental results show that the fitting degree between the measured value and the true value of the sensor for detecting harmful gases can reach over 99％,reflecting high detection accuracy.Moreover,the sensor is in a reversible ionization e-quilibrium state when detecting harmful gases,with good repeatability and without preheating.It is safe and non-toxic.Therefore,it is suitable for application in the detection of benzene gases,meeting the re-quirements of efficiency and accuracy,and has certain practicality.
