FUEL CELL POWERED PORTABLE ELECTRONIC DEVICES

摘要

A wrist-mountable portable electronic device comprises an electronic device which is incorporated into a housing and a strap, coupled to the housing and configured to retain the wrist-mountable portable electronic device on the wrist of a user. The strap incorporates at least one fuel cell coupled to provide power to the portable electronic device. The portable electronic device may be a watch or a personal communication device or a personal health and/or activity monitor. The strap may further include an integral fuel source coupled to the at least one fuel cell, and the fuel source may be a replaceable cartridge. High power devices to be worn on the wrist may therefore be powered for extended periods of time.
