Power on the go

Mobile devices are becoming more and more intelligent – allowing users to watch movies on a mobile phone or laptop, or navigate with a PDA – but at the same time they require increasing amounts of power. To prevent the PC screen from suddenly going black, or the music from being interrupted, Fraunhofer researchers are working on micro power engineering solutions to provide the mobile power needed by modern communications devices. The latest examples of their work can be seen at the Hanover Trade Fair.
