In this paper, a dual band planar inverted F antenna (PIFA) has been investigated for cooperative onand off-body communications. Free space and on-body performance parameters like return loss, bandwidth, radiation pattern and efficiency of this antenna are shown and investigated. The onand off-body radio propagation channel performance at 2.45 GHz and 1.9 GHz have been investigated, respectivel...

Antenna design for footwear is an essential part of enabling reliable wireless links with lower-limb sensors used in body centric networks. Sensors can report biomechanical pressure data to analyse kinematic and posture parameters for a range of medical and sporting applications. Consideration is given to antenna shapes, the fit with shoe shapes, the positioning on the shoe and the radiation pa...

Games & Learning We are well aware that video games are ca using educators to take a second l ook at t he e ducational value o f games, technology, and the social interactions involved (de Castell & Jenson, 2004; Gee, 2 003; Shaffer, Squire, Halverson, & Gee, 2005) but what does that learning look like, how does that l earning o r way of knowing happen, and what do the gamers h ave to say abou ...

In this paper, a switchable textile communication system working at 2.45 GHz ISM band is presented and studied for different locations within a realistic on-body environment. A 3D laser scanner is used to generate a numerical phantom of the measured subject to improve the accuracy of the simulations which are carried out for different body postures. For the off-body communications, the system i...
