Wireless electricity or WiTricity is the transfer of electric energy or power over a distance without the use of wires. In order for the energy to be transferred safely coupled resonators are used. Coupled resonators are two objects of the same resonant frequency that exchange energy efficiently without much leakage. Minimizing energy leakage is very important because the goal is to have as much energy as possible be transferred from one object to another.
Witricity is the shortform of wireless electricity.it means we can transfer electricity without the use of wires. it can be used in many fields like household appliances,automobiles,electronic devices etc. By using witricity we can avoid the power losses occuring when transmission occurs.

WiTricity technology is a non-radiative mode of energy transfer, relying on the magnetic near field. Magnetic fields interact very weakly with biological organisms—people and animals—and are scientifically regarded to be safe.
Wireless power transmission has become the new era in modern technology.The usage of this system is increasing day by day.This slide contains basic elementary topics about wireless power transmission.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

In our present electricity generation system we waste more than half
of its resources. Especially the transmission and distribution losses
are the main concern of the present power technology. These losses
imply that our present system of electrical distribution is only 70-
74% efficient.
We have to think of alternate state - of - art technology to transmit
and distribute the electricity. Now- a- days global scenario has been
changed a lot and there are tremendous development in every field.
We have to keep pace with the development of new power
technology. The transmission of power without wires may be one
noble alternative for electricity transmission.
3. WITRICITY stands for wireless electricity.
The transmission of energy from one place to another
without using wires. It eliminates the use of cables.
It is the transfer of power to a device over the air. Power
source (transmitter) provides power to the devices whereas
capture device (receiver) captures it.
Efficiency achieved was around 40%
Used frequencies are 1MHz &10MHz
Intel is working on it
4. HISTORY OF WIRELESS POWER
In 1899, Sir Nikola Tesla proposed a
method of Wireless Power Transmission.
His vision was for “World Wireless
System”.
The 187 feet tall tower was built to
broadcast energy. So that, all people could
have access to free energy but shortage
of fund led to nonoperation.
Tesla was able to transfer energy from
one coil to another coil and he managed
to light 200 lamps from a distance of
40km.
As it was in Radiative mode, most of the
power was wasted and had less efficiency.
The idea of Tesla is taken into research
after 100 years by a team led by Marin
6. WIRELESS POWER TECHNOLOGY
Various methods of wireless power transmission:-
Near-field techniques
Inductive Coupling (works on mutual induction)
Resonant Inductive Coupling (resonance & inductance)
Air Ionization (ionized air due to high field)
Far-field techniques
Microwave Power Transmission (MPT) (capturing
microwaves using rectenna)
LASER power transmission
Witricity works on the principle of Resonant Inductive
Coupling(RIC).

7. Resonant inductive coupling or electrodynamic induction is the
wireless transmission of electrical energy between two magnetically
coupled coils that are part of resonant circuits tuned to resonate at the same
frequency.
A transmitter coil in one device transmits electric power across an
intervening space to a receiver coil in another device.
The capacitor and inductor forms the resonator. Charge oscillates between
inductor (as magnetic field) and capacitor (as electric field). This generates
an oscillating magnetic field.
This type of oscillation is called resonance if the reactance's
of the inductor and capacitor are equal.
Because the coil is highly resonant, any energy placed in the coil dies away
relatively slowly over very many cycles; but if a second coil is brought near
it, the coil can pick up most of the energy before it is lost, even if it is some
distance away.
8. Coil provides the inductance which induces current.
Capacitor is connected parallel to the coil
Energy will be shifting back and forth between magnetic field surrounding
the coil and electrified around the capacitor.

10. 1. Magnetic coil (Antenna A) is housed in a box and can be set in
wall or ceiling.
2. Antenna A, powered by mains, resonates at a specific
frequency.
3. Electromagnetic waves transmitted through the air.
4. Second magnetic coil (Antenna B) fitted in laptop/TV etc.
resonates at same frequency as first coil and absorbs energy.
5. Energy charges the device.
11. APPLICATIONS
Consumer Electronics:-
Automatic wireless charging of electronics in home, cars,
offices.
Wireless charging pads(Mobile phones, Laptops, Game
controllers etc.)
Electric Toothbrushes
Industrial Applications:-
Direct wireless power and communication interconnections
at points of use in harsh environments.
In Drilling, Mining, Underwater etc.
Transportation:-
Automatic wireless charging for existing electric vehicle
classes.
In Golf carts, Cars etc.
Other Applications:-
Medical devices
Military applications
15. ADVANTAGES

No need of line of sight.
Magnetic fields interact weakly with biological
masses (humans).
No wire, No batteries i.e. No e-waste

16. DISADVANTAGES
Distance constraint:-Transmissions possible only in
few meters. Efficiency decreases with distance.
Possibility of “energy theft”
The resonance condition should be satisfied and if any
error exists, there is no possibility of power transfer.
Initial cost is high
In RIC, tuning is difficult
High frequency signals must be the supply.
• Need for standardization and adaptation. So no
overheating occurs because of different voltages.

17. FUTURE OF WITRICITY
• If we apply this idea to the whole city, we might not have
to use any wired cable. Moreover, in the future, it would
save the material cost, and “WE CAN SAVE THE WORLD,
YEAH!!!”
18. ECONOMIC IMPACT
The concept looks to be costly initially but the cost is
not estimated yet.
In terms of economic theory, many countries will
benefit from this service. The private, dispersed sub-
stations will be needed.
No power cords will be necessary
Monthly electric utility bills from old-fashioned, fossil-
fuelled, loss-prone electrified wire-grid delivery services
will be optional.
19. CONCLUSION
The transmission of power without wires to any terrestrial
distance is not a theory or a mere possibility, it is now a reality.
Dr.Tesla is the pioneer of this invention.
Wireless electricity have tremendous merits like high
transmission integrity and Low Loss (90 – 97 % efficient)and
eliminate the need for an inefficient, costly, and capital
intensive grid of cables, towers, and substations.
It has negligible demerits like energy theft and difficult tuning.
Many countries will benefit from this service.
The wireless transfer of electricity has been a sci-fi dream up
to this point, and truly, if electricity could simply be in the air, in
the same way radio waves and Wi-Fi signals are, it would
change the world.
