- One major limitation in WSN is the lifetime of the node’s battery. AIM: To overcome the power constraint in WSN by wirelessly charging the nodes using a newly discovered technique for single hop wireless energy transfer called Witricity.
- The investigated design consists of two copper coils, each a self-resonant system. One of the coils, attached to the power source, is the sending unit. Instead of irradiating the environment with electromagnetic waves, it fills the space around it with a nonradiative magnetic field oscillating at MHz frequencies. The non-radiative field mediates the power exchange with the other coil (the receiving unit), which is specially designed to resonate with the field. The resonant nature of the process ensures the strong interaction between the sending unit and the receiving unit, while the interaction with the rest of the environment is weak.
- Integrating Witricity into WSN requires considering multi-hop wireless energy transfer since most nodes are several hops away from the base station. three new techniques for multi-hop wireless energy transfer
