CoilMove

Abstract

Today, users are an integral part of charging their mobile and wearable computing devices, including smartphones, smartwatches, fitness trackers and music players. In this paper CoilMove is presented. CoilMove is an actuated wireless energy transfer system, envisaged as being embedded within a surface in a user's ambient environment, such as a floor or table. CoilMove transfers energy to devices located on the body and can recharge our mobile and wearable devices through inductive power transfer without the need for user input. CoilMove is capable of locating a device on a user's body through the presence of a magnet on the device. The user need not be aware of the interaction and from a user perspective devices would appear to charge themselves. Furthermore CoilMove is compliant with international guidelines on time-varying magnetic fields present in inductive power transfer systems, affording prolonged system use.
