Sir, This innovation is to repell mosquitoes from the body. I have made a bracelets that can be put on arm or leg , after this mosquito will not be able to bite that person. It become activated after putting on the body and get deactivated as soon as kept it away. It is a cheap source as in this only cell of wrist watch,mini motor and other household things are used. Every common man can afford it. It does not have any adverse effect on the body , it just produce vibration and by this mosquitoes won't come near the person having that bracelet . I got this idea by the medium of cattle rearing. Animals have some naturalbability to save themselves from mosquitoes by vibrating their bodies. From here I got this idea. This bracelete can also be used for animals by tying it around their necks. It also relieve people from the use of sprays and coils, as these can have some type of harmful effects for the body.
