Technological solutions which possess to obtain MOX sensors in SMD form-factor include the combined usage of silicon MEMS microhotplate [3-6], SMD package made of different materials such as plastic [3], metal-plastic [4] and metal-ceramic [5, 6].
MOX gas sensitive materials are known by their low selectivity, which prevents some applications for MOX gas sensors.
Materials and Methods After long-term experiments with wide spectres of perspective ceramics MEMS technologies [22] and materials (ZrO2 [23], Al2O3 [24], LTCC [25]) used for MEMS platforms fabrication we have chosen combination of the laser micromilling of monolithic ceramics (further will describe the result based on 99,9% Al2O3 commercially available) and printed technologies to form metallization on MEMS microhotplate and SMD package.

High temperature oil water will cause the oil drops splashing, water mist spray fire if there is high or burning oil drops from splashing out, can cause personal injury, or ignition of combustible materials nearby causes the fire spread,as a result the nozzle working pressure is too high, the droplet diameter is larger and other factors Through the experiment in the process of observation, we found the selection coefficient is1.3 when the applicator has splash phenomenon, the pan around the ground floor there is a trace of oil splash.
