What is Witricity
Electricity without wires
Magnetic loop antennas
Electromagnetic near-field
Need of WiTricity
Now a days there is a Rapid development of autonomous electronics like Laptops, Cell-phones, House-hold robots and all those devices typically rely on chemical energy storage(Battery) As they are becoming daily needs to present generation, Wire less energy transfer would be useful for many applications as above and they need midrange energy.
Basic Principle
The basic principle involved in Witricity concept is, Two objects having same resonating frequency and in Magnetic resonance at Strongly coupled regime tend to exchange energy , while dissipating relatively little energy to the extraneous off-resonant objects.
Advantages
No need of line of sight
No need of power cables and batteries
Does not interfere with radio waves
Wastage of power is small
Negative health implications
Conclusion :-
Witricity is in development stage, lots of work is to be done to use it for wireless power applications. Currently the project is looking for power transmission in the range of 100w. Before the establishment of this technology the detailed study must be done to check whether it cause any harm on any living beings.
