Analysis of Magnetically-coupled Human Body Communications

چکیده
In this paper magnetically-coupled human body communications (MHBC) is investigated. In human body communications (HBC) the human body is the transmission medium through which wireless sensors and actuators in, on or in close proximity to the human body exchange information. MHBC, unlike the more common galvanic and capacitive coupled HBC, is less affected by the proximity to the surrounding environment, with the exception of materials with high permeability. Therefore, MHBC offers tremendous potential for the implementation of personalised healthcare systems. In this work MHBC is investigated using finite element analysis through COMSOL. A communications scenario involving the human arm is explored for investigating transmission parameters. COMSOL simulation results demonstrate the MHBC technique and highlight the importance of finite element analysis as a powerful tool for investigating the performance of MHBC systems.

Non-verbal communications could be a part of visual signs that, because of their importance in interpersonal relationships and transition of meaning, are highly regarded by psychologists and sociologists. One of the major subdivisions of this topic is called "Body Language" that has existed in all human societies since ancient times. These non-verbal signs, some thousands of years old, have cul...
متن کاملA Coupled Random Fixed Point Result With Application in Polish Spaces
In this paper, we present a new concept of random contraction and prove a coupled random fixed point theorem under this condition which generalizes stochastic Banach contraction principle. Finally, we apply our contraction to obtain a solution of random nonlinear integral equations and we present a numerical example.

The aim of this paper is to establish some fixed point theorems for $alpha$-admissible Mizoguchi-Takahashi contractive mappings defined on a ${b}$-metric space which generalize the results of Gordji and Ramezani cite{Roshan6}. As a result, we obtain some coupled fixed point theorems which generalize the results of '{C}iri'{c} {et al.} cite{Ciric3}. We also present an application in order to i...
متن کاملMagnetic memory based on magnetic alignment of a paramagnetic ionic liquid near room temperature.
A paramagnetic ferrocenium-based ionic liquid that exhibits a magnetic memory effect coupled with a liquid-solid phase transformation has been developed. Based on field alignment of the magnetically anisotropic ferrocenium cation, the magnetic susceptibility in the solid state can be tuned by the weak magnetic fields (<1 T) of permanent magnets.
