Abstract
A power-free wireless operation device of a portable electronic device includes a portable electronic device that includes a device-side matching unit, a radio frequency unit, a device-side wireless communication interface, and a message processing unit and a wireless operation mechanism that includes a matching unit, a current processing unit, a wireless communication interface, and an operation processing unit. As such, a keyboard is operable with power supply from a portable electronic device so that the keyboard does not need to be equipped with an own power supply, whereby the present invention allows for significant reduction of the size of a wireless operation device and, in manufacture and production, a design can be adopted to achieve the features of being light, thin, and compact and being readily foldable for easy carrying and providing an effect of environmental protection through regeneration.
