“…Recently, there is increasing interest for developing new medical and health monitoring systems to relieve the problems and demands of healthcare due to aging population. [1]- [4]. Gastrointestinal (GI) diseases have growing trend in the developed countries and thus, the GI monitoring systems such as stomach, small intestine (SI) and colon monitoring systems, as well as capsule endoscopy, have been under an intensive study in recent years [5]- [6].…”

This paper presents a study on the power distribution within the tissues for abdominal monitoring and implant communications systems. This study is carried out using finite integration technique based simulations with an anatomical voxel model as well as with recently introduced directive on-body antennas designed for in-body communications. The investigation is conducted by evaluating 2D power flow on the cross-cut of the abdomen area to illustrate the propagation inside the different abdominal tissues. Additionally, power values in different parts of the abdomen area, such as in different parts of the small intestine (SI), colon, stomach etc., are calculated. The main purpose is to examine power distribution in the abdominal area with different antenna location options suitable for abdomen monitoring systems. Furthermore, channel characteristics between an endoscope capsule and an on-body antenna are evaluated in two different areas of the SI tract: close to the on-body antenna and further from the on-body antenna. Power distribution information is useful when designing the medical and health monitoring devices for the abdomen area, such as capsule endoscope, gastrointestinal activity monitoring systems, etc.

In this paper, ultrawide band (UWB) communication systems with eight transmitting and receiving ring antenna arrays are implemented to test the bit error rate and capacity performance. By using the ray-tracing technique to compute any given indoor wireless environment, the impulse response of the system can be calculated. The synthesized beamforming problem can be reformulated into a multiobjective optimization problem. Self-adaptive dynamic differential evolution (SADDE) and particle swarm optimization (PSO) are used to find the excitation current and the feed line length of each antenna to form the appropriate beam pattern. This pattern can then reduce the bit error rate and increase the channel capacity and receiving energy. Numerical results show that the fitness value and the convergence speed by the SADDE are better than those by the PSO. Moreover, the SADDE had better results for both line-ofsight and nonline-of-sight cases. In other words, compared with PSO, SADDE has improved more effectively the main beam radiation energy and reduced the multipath interference.

“…Communication between several implantable medical devices could facilitate a wide range of medical applications, enhancing minimally invasive healthcare and long term treatments through, for instance, physiological monitoring of transplanted organs or the control of smart limbs or prosthetics [1], [2]. Within such an Intra-Body Network (IBN) the path between the nodes may be physical short but it is envisaged that some applications will require communication over longer distances and through several tissue types exhibiting different dielectric properties.…”
