Özet:

 Intrabody communication is an innovative method that utilizes the human body as a communication channel for transmitting electrical signals. In this study, the galvanic coupled intrabody communication channel for wearable systems was analytically investigated using a distributed parameter transmission line model up to 100 MHz. The proposed model enables a detailed analysis of the transmission line behavior by considering the frequency dependent electrical properties of the tissue. The results indicate that the resistance and capacitance in the equivalent circuit decrease with increasing frequency, while conductance increases. Notably, the attenuation and phase constants were found to reach their maximum values at 100 kHz within the investigated frequency band, measured as 3.85 Npm and 3.58 radm, respectively. Additionally, it was observed that the transmitted power in communication increases with frequency at the same distances. These findings provide critical insights into the design of communication channels in next-generation wearable systems and establish a guiding framework for optimizing system performance through frequency selection. This study aims to contribute to the development of intrabody communication systems for low-power and high-efficiency data communication.

 Vücut içi haberleşme, insan vücudunu elektriksel sinyallerin iletimi için haberleşme kanalı olarak kullanan yenilikçi bir yöntemdir. Bu çalışmada, giyilebilir sistemlere için 100 MHze kadar olan farksal bağlaşımlı vücut içi haberleşme kanalı, dağıtık parametreli iletim hattı modeli kullanılarak analitik olarak incelenmiştir. Söz konusu model, dokunun frekansa bağlı elektriksel özellikleri dikkate alınarak iletim hattı davranışının detaylı bir şekilde analiz edilmesini sağlamaktadır. Elde edilen sonuçlar, eşdeğer devredeki direnç ve kapasitansın artan frekansla birlikte azaldığını, kondüktansın ise arttığını göstermektedir. Özellikle, zayıflama ve faz sabitlerinin incelenen frekans bandında 100 kHzde sırasıyla 3,85 Npm ve 3,58 radm ile en yüksek değerlerine ulaştığı belirlenmiştir. Buna ek olarak, haberleşme kanalında iletilen gücün frekans arttıkça aynı uzaklıklarda artış gösterdiği gözlemlenmiştir. Bu bulgular, yeni nesil giyilebilir sistemlerin haberleşme kanalı tasarımı için kritik bilgiler sunmakta ve sistem performansını optimize etmek için frekans seçimi açısından yol gösterici bir çerçeve oluşturmaktadır. Bu çalışma, düşük güçlü ve yüksek verimli veri haberleşmesi için vücut içi haberleşme sistemlerinin geliştirilmesine katkı sağlamayı hedeflemektedir.
