Wireless Sensor Nodes (WSN) is powered by small batteries and the limited energy supply has constrained the lifetime of a sensor network. This has been a long lasting, fundamental problem faced by sensor networks that are designed for long term operation. The issue in energy constraint problem in WSN and as a solution, WiTricity (Wireless elecTricity) is proposed. Energy will be shifting back and forth between magnetic field surrounding the coil and electric field around the capacitor. Primary and secondary coils (helical shape) are used to transfer the energy from energy station to sensor nodes.
