Low Efficiency

This chapter gives an overview on Wireless Power Transfer (WPT) systems and the existing biologically-inspired architectures which could be used to optimize the efficiency of the systems. In general, wireless power transmission could be categorized into near-field and far-field mechanisms. At present, one of the most immediate issues to be solved is the relatively low efficiency in a WPT system. The system's efficiency decreases gradually as the distance increases. To ensure highest efficiency, the path with the shortest distance and the lowest interference is to be selected. In this case, a few of the most popular biologically-inspired algorithms, i.e. Firefly Algorithm(FA), Simulated Annealing (SA), the Ant Colony Optimization (ACO) and Genetic Algorithms (GAs) could be employed for efficiently solving different optimization problems. In short, these algorithms mentioned involve the emulation of fireflies flash signals for mating, exploitation of the metallurgy process, nature of ants leaving pheromones along the trails traveled and also the mimic of gradual evolution of organisms.

Transmission Quality

We developed and evaluated different textile-based inductive coils for near-field wireless power transmission. The technology uses electromagnetic induction for the contactless transfer of electrical energy. Therefore, we investigated various methods for the attachment of conductive materials on a textile-based material and the production of textile-based coils based on QI standard. Afterwards, the textile-based coils were examined and evaluated due to their specific quality characteristics. This happens by calculating the transmission quality and the maximum efficiency of the system which enables comparison of different coil systems and indicates the transmission efficiency of the systems.
