Download A Novel Intrabody Communication Transceiver for Biomedical by Mir Hojjat Seyedi, Daniel Lai PDF

By Mir Hojjat Seyedi, Daniel Lai

This monograph explores Intrabody communique (IBC) as a unique non-RF instant info communique method utilizing the human physique itself because the conversation channel or transmission medium. specifically, the booklet investigates Intrabody communique contemplating limb joint results in the transmission frequency diversity 0.3-200 MHz.

Based on in-vivo experiments which ensure the results of dimension, occasions, and destinations of joints at the IBC, the publication proposes a brand new IBC circuit version explaining elbow joint results. This version not just takes the limb joint results of the physique into consideration but in addition considers the impact of size apparatus in larger frequency band therefore predicting sign attenuation habit over wider frequency levels. ultimately, this paintings proposes transmitter and receiver architectures for intrabody communique. A carrier-free scheme in line with impulse radio for the IBC is carried out on a FPGA.

However, the FEM is created from arbitrary number of nodes (more than thousands) to construct only one mesh. According to Wegmueller [6], to model the body channel using the FEM, mesh sizes were between 150000 and 200000 elements. Therefore, employing the circuit model could reduce the complexity as well as the analysis duration. 4 Circuit-Coupled FEM Model Circuit-coupled FEM provides useful insights into the capacitive coupled IBC. It allows modeling of IBC channel components with different abstraction levels.

The average (Avr) and standard deviation (SD) are calculated between the achieved results from all subjects calculated between the achieved results from three subjects (see Fig.

4 IBC Transceiver Design 23 in [70]. The WBS scheme directly transmits binary digital signals through wideband pulse signals. Lin et al. [67] implemented the small size system on a chip (SOC) IBC system for biomedical applications for the first time. The authors believed that the suitable carrier frequency for IBC was 200 MHz and data rates up to 2 Mbps were reported for OOK modulation. 5 V making it suitable for use with solar cell power. Unfortunately, this system had a short channel length or transmission distance (from subject’s wrist to forearm).
