In this paper, the development of explosive detection with MEMS technology was briefly reviewed. Various detecting methods were classified in microcalorimetric spectroscopy, optical displacement measuring, resonance frequency shift measuring, piezoresistive strain monitoring, heat absorption or release monitoring, and FA-IMS. Advantages and disadvantages of each method were respectively discussed.
Using the method of ANSYS finite element analysis, we calculate the electric field interference between the ionization electrodes and ion filter electrodes. The effect of varying the electrodes width and distance on the electric interference field intensity has been investigated. In this paper, a method for selecting the electrodes width and distance is proposed by synthetically considering ions recombination...
