Review Paper on Wireless Power Transmission for Energy Harvesting System

According to current stage every human being wireless system as we know there is lots of systems are there which are use for wireless communication like GSM, WiFi, BLE, Bluetooth etc. Now if we are talking about wireless power transmission so this is still a current research area for all researchers. Right now we are using wire system for power transmission but everyone demand wireless system. Right now there is lots of commercial and non commercial sector where everyone need wireless power transmission system, those sector like WSN networking, Remote Location based industries etc. These applications are currently using battery system or direct wired system now if we are talking about WSN network system so those system are require less power and working on battery but lifetime of battery is limited so thats why there is need of wireless power system. In this paper basically we did comparative study about the previous existing wireless power transmission system and find out some research issue which can be treating like a future research objective for this area.
