However, part of the AC electric field induced on the body returns to the ground on the transmitter, and a significant part escapes directly to the earth ground. To do this, we created a differential structure in the initial stage amplifier of the receiver and developed technology with a careful design from the receiver electrode to the positive input of the initial stage low-noise amplifier and from the ground electrode to the negative input terminal to achieve an equivalent differential structure.
This article has multiple issues. The near-body electric field is modulated eedtacton can be read and demodulated through these couplings. Common-mode noise suppressed by differential architecture. This is constant for full duplex communication.
What is RedTacton & How It Works? –
Take a look at the figure below to know the exact comparison between all the technologies. Wired communication transmits data between two connection points, so interception is difficult and security can be considered to be high. This could get as simple as two people equipped with RedTacton devices being able to exchange data just by shaking hands.
Is tis harmful to our body…. A key aspect of the technology is the behavior of the AC electric field, which can be summarized in terms of three components produced around the body when an AC signal is applied to a parallel-plate electrode attached to the body. Previous post Redtactonn post.
The first person to study this sort of electric-field communications technology, as a means of communication among multiple wearable computers that users would attach to their bodies, was T. This enabled us to develop a near-body quasi-static electric-field communications technology capable of providing the quality required for communications services while using a minimum level of power in the transmitter.
At any point of time, you can contact us and select the data you wish to anonymise or delete so it cannot be linked to your email address any longer. He built a prototype electric-field communications system using kHz and demonstrated the potential of the concept .
The advent of RedTacton technology by NTT is in itself revolutionary, which will likely be targeted for use in applications such as wireless headphones, wearable medical devices, security applications, point-of-sale interactions etc. Wireless communication creates connections when signals arrive, allowing for easy connections because connectors are unnecessary.
But, there will not be many problems with security. We have discussed about various infrared and Bluetooth wireless technologies in our recent posts. His technical areas of interest include timing jitter analysis of high-speed sampling systems, electro-optic sensors, high-precision waveform measurement for ultrafast electronics, electric-field measurement of printed circuit boards, and communication technology for human area networks.
I am doing research on technology for developing my design project. Now, researchers are trying to develop a new path for transmission of signals called Human Area Networking.
The transmitter can operate for approximately one year using a single CR button-type lithium-ion battery. Principles and strengths of the technology A model of the distribution of the electric field around the human body is shown in Fig.
Human society is entering an era of ubiquitous computing, where networks are seamlessly interconnected and information is always accessible at our fingertips. But the technology has been advanced that these technologies have been overrated. RedTacton Transceiver Block Diagram.
This page was last edited on 10 Septemberat We are continuing to expand these application areas together with various partners. A transmission path is formed at the moment a part of the human body comes in contact with a RedTacton transceiver. A laser is passed though an electro-optic crystal, which deflects light differently according to the strength of the field across it.
RedTacton Near-body Electric-field Communications Technology and Its Applications
When compared with a wi-fi communication, this technology seems advantageous. It can provide maximum security as well as data transfer without the use of physical connections. Nippon Telegraph and Telephone Technology stubs. We also added a function enabling the reactance circuit to follow changes in this floating capacitance as the body moves, resonating with it.
