Wireless charging Mouse

Wireless charing in Mouse

 In my wireless mouse I need to change the battery every 30 days as they get exhausted... So I replaced them with rechargable Li-ion battery but For that too i need to charge them every 40-45 days... So got an idea to implement wireless charging in it... It uses mousepad as Wireless transmitter and a receiver inside the mouse.
