NANO-BIOELECTRODE FOR SECURED INTRABODY COMMUNICATIONS

MAKERS: UTHAYAKUMAR G S

Intra-body communication (IBC) is an alternative wireless communication technology which uses the human body as the signal propagation medium. IBC has characteristics that could naturally address the issues with RF for BAN technology. This survey examines the on-going research in this area and highlights IBC core fundamentals, current mathematical models of the human body, IBC transceiver designs, and the remaining research challenges to be addressed. IBC has exciting prospects for making BAN technologies more practical in the future. The IBC system is a protected and private communication network which provides natural security and interference-free communication. The required operating frequency of IBC is much lower compared to RF system. The design of the circuit involves with the three major components such as Microcontroller, LCD display and Accelerometer sensors. Using accelerometer sensor the password is entered using three-dimensional system i.e. along X-axis, Y-axis and Z-axis, we must draw a code word, based on the standard values along the entire three axis, it will be recognized exactly and it will open the door. In this human body security system the microcontroller zigbee has the maximum data rate of 250 kb/s at 26.5mW resulting in 106nJ per received bit but IBC consumes an order of magnitude less energy at data rates up to 10Mb/s which makes it an attractive communication method for HBAN applications. In this research work, we introduced a low-cost novel surface electrode to detect the human body signals.This project has satisfactorily overcome the issues addressed by the RF wireless technology used in existing system. As we make use of human body as a medium the system becomes more efficient and advantageous. The security system is improved by making use of this concept since it provides natural security. As it consumes less power it increases the practical duration of the system. It provides an interference free communication and also there will be no signal leakage and it uses a lower frequency ranges. Due to all these reasons the security has been improved and its implementation is also simple.
