ABSTRACT:
The aim of this paper is to introduce a new system of transmitting the power which is called as wireless electricity or witricity.
What is witricity?
} Electricity that is transferred wirelessly between two electromagnetic coils resonating at the same frequency
HOW IT WORKS?
} "Resonance", a phenomenon that causes an object to vibrate when energy of a certain frequency is applied.
TYPES OF WIRELESS TRANSMISSION:
} Near field
Induction
Resonant induction
} Far field
Radio and microwave transmission
Laser
Electrical conduction
ADVANTAGES-
} With the advent of wireless communication consumers are realizing that life without physical cables is easier, more flexible and often less costly.
} Higher power application and any low-power device.
} In wireless communication protocols.
DRAWBACKS-
} The method for transferring electrical power would be both inefficient and dangerous, when the radio waves spread in all directions until they reach antennae that are tuned to the right frequency.
} Main drawback is to Induction technique.
APPLICATIONS-
} In laptop computers or MP3 players without wires
} In implantable medical devices
} Used to charge electric toothbrushes.
CONCLUSION -
} That wireless power transmission is going to be a major field of interest for scientists and for people.
} It is a rocking technology provided the researches continue to move in same speeding direction.
