EEG biomedical signal transmission using visible light communication

Abstract

The proliferation of radio frequency communication technology in biomedical signal transmission is frequently flustered by electromagnetic interference (EMI). The impact of EMI radiation has the consequences of the reduction in accuracy and reliability. Even though its flexibility and mobility have wide attraction, the radiation brings damage to hospital equipment and even harm to the humans. Biomedical signals such as Electroencephalography (EEG) are most utilized signals, which measures the electrical brain rhythms and has huge capability to identify or determine the cause of diseases. In this paper, we propose a EEG signal transmission system using visible light communication. We employ On-Off Keying (OOK) modulation scheme for transmitting the data and RGB LEDs and photodiodes are used for uplink transmission. Computer simulations are carried out using 10 channels of raw EEG signals with the precision of signal values mainly focused. The results demonstrate that it achieves a Bit Error Rate (BER) better than 1.5x10 −5 at a Signal to Noise Ratio (SNR) value of 7 dB, thus exhibiting robust reliability and accuracy compared with conventional transmission methods.

Optical Wireless Network Design for Off-Body-Sensor Based Monitoring

“…e majority of works have proposed VLC uplink use to transmit health data from sensors. e studied configurations are generally static as in [19][20][21][22] and concern ECG and EEG data. In [23,24], an image sensor is used for the visible signal reception.…”

Noise Analysis in VLC Optical Link based Discrette OP-AMP Trans-impedance Amplifier (TIA)

“…Several companies/institution that developing VLC technology are: Nakagawa Laboratories (Japan) [1], Disney research (Switzerland) [2], pureLifi Ltd (UK) [3], IMDEA Network Institute (Spain) [4], and many more. Besides that, many universities also provide laboratorium access for VLC technology research, for example: Institut Teknologi Bandung (Indonesia) with research [5][6][7][8][9][10][11][12][13][14][15][16][17], Pukyong National University (South Korea) with research [18][19], Edinburgh University (Scotland) with research [20][21], National University of Singapore (Singapore) collaboration with Nanjing University (China) with research [22], Chulalongkorn University, Thailand [23], Kookmin university (South Korea) with KUET (Bangladesh) [24], etc.…”

A Hybrid Optical-Radio Wireless Network Concept for the Hospital of the Future

“…VLC presents an alternative solution for transmitting bio signals where these are less susceptible to artifacts. Dhatchayeny et al [8] presented a study in which an EEG signal can be transmitted efficiently on VLC without any loss, as might be the case in radio transmissions. EEG signal comprises of multiple frequencies describing the ongoing activities in different parts of brain, thus transmitting each frequency separately is critical for proper diagnose.…”
