BatteryFree Wireless Optical Mouse
 

A4 Tech has created quite an interesting little gadget with their
BatteryFree Wireless Optical Mouse. The mouse uses RFID technology to
communicate position and button states to a mouse pad which plugs into your
USB port. Even more interestingly, the pad transmits power to the mouse
through inductance, so that the mouse needs no batteries for power. This
results in a mouse with no wires leading out of it and which is far lighter
than conventional wireless mice. In fact, it’s a bit lighter than my
conventional wired optical mouse. The RFID technology makes it much less
likely than Bluetooth that you will ever have interference from other
devices, but it does require the use of the pad. For some this may not seem
to meet the full definition of “wireless”.
