Abstract

In this paper we introduce to the current State-of-the-art in Wireless Sensor Network charging for Smartphones in automobiles, the technology that will sit alongside with features such as touch-screen and Natural Voice Recognition (Text-to-Voice). It can offer charging for iPhones and some Android devices based on Qi (inductive power standard). An automobiles Qi system is based on Wireless interface standard for inductive electrical power transfer over distances of up to 4cm (1.6 in) comprising a power transmission pad and a compatible receiver on top of which a mobile device is placed. The rubberized Power mat wireless charging pad will be positioned inside the storage bin of a cars center motorized instrument panel faceplate. It will also have built in NFC tags which can automatically execute tasks on your smartphone (like placing and receiving calls) when mounted and launch alarm clock or Google Maps by illuminating LED lights when a device is nearby. The proposed Qi enabled devices would replenish the batteries with a power transfer capability of around 0.5W at a maximum distance of 2.5cm to address energy efficient lifetime bottlenecks in sensor networks
