The long-lasting insecticide-treated mosquito net plays an important role in the health sector, which is well known to all. However, whether it is hot or cold man is supposed to stay under this mosquito net lest he be bitten by mosquitoes, because it has a limited range of action that is insignificant compared to the apartment or living room that we occupy.
In an effort to broaden our range of action, we conducted biological research on what could hinder or scare a mosquito into a radius greater than that of an impregnated mosquito net, without affecting or interfering with humans.
The infrasound and the ultrasound are perceptible by certain animals and insects, on the other hand they are inaudible in the man. Only the frequency range from 20Hz to 20KHz is audible by the human ear. And it is the oscillators that are able to produce infrasound and ultrasound. In the case of mosquitoes, we have proposed relaxation oscillators that can produce a signal with a frequency of 62.6KHz to keep mosquitoes away from a distance without disturbing humans. Our assembly is easy to be realized and to be assembled, less expensive, having usual components and being able to be supplied starting from a tension ranging from 6 to 12 volts.
