Adapting portable electrical devices to receive power wirelessly

摘要

Wireless power receiving apparatus (150) is retrofitted to a portable electrical device (100) to enable the portable electrical device (100) to receive power wirelessly. The wireless power receiving apparatus (150) comprises a power-receiving element (200) adapted to be attached to the portable electrical device (100), e.g. by adhesive (201), and also being adapted to receive power wirelessly from a transmitter of power when the power-receiving element (200) and transmitter are in proximity with one another. One or more power connectors (203) are connected electrically to the power-receiving element (200) and are adapted to be connected, when the wireless power receiving apparatus (150) is in use, to one or more corresponding power connectors (101) of the portable electrical device (100) to deliver power received by the power-receiving element (100) to the portable electrical device (100). The power-receiving element (200) may be in the form of a sticker or may be carried by or incorporated in a replacement cover portion for the portable electrical device (100).
