A brain sensor antenna eeg remotely

I plan to create an eeg brain sensor antenna to remotely record eeg with a range limit of 5 km

The antenna is a more clean solution than a headset. The antenna if proven to work could be added to a satellite in space to monitor the brains of the entire world

    There is a way to read the brain in plain text. You need the eeg data In csv format. You need to count the frequency of each eeg value. You create a list of top frequent eeg number. You replace the list with a second list of words. Eeg numbers become words that are readable.

    Vinny, hi.

    I plan to create an eeg brain sensor antenna to remotely record eeg with a range limit of 5 km

    EEG brainwaves AT THE SCALP, are only in the microvolt range, say from a few microvolts to around 80 microvolts. Once any sensor is separated from scalp contact, any signal level drops to be undetectable. Because of ambient noise levels. This is why EEG needs scalp contact.

    You create a list of top frequent eeg number. You replace the list with a second list of words. Eeg numbers become words that are readable.

    I'm sorry, but this is not how EEG works. There are no direct EEG to language interfaces.

    as soon as we deal with waves, long range antennas have the capacity to read the waves. it's brain waves so they can be read with an antenna as soon as the waves emit, they can be read. the brain in theory shows up through software as a wifi network can show up on windows 10. the antenna can be powerful so the brain waves can be weaker it doesnt matter the antenna picks it up

    long range antennas have the capacity to read the waves.

    Please re-read my previous comments. EEG is a very very weak signal, only detectable at the scalp with very sensitive amplifiers (such as OpenBCI or others). Wifi and Bluetooth signals are hugely stronger microwave level transmissions. The brain does not send out microwaves. Brainwave frequencies are generally in the range of about 1 Hz to 40 Hz. Such low frequencies do not have the power to travel kilometers.

    Here is some reading for you:

    The image you posted is nonsense. Impossible. I'm sorry but that is just the way EEG works. If you are interested in EEG 'speller' applications, they do exist. But they do not operate the way you think.

    the antenna has to emit powerfully to connect to the brain, even if EEG is weak it can connect. alot more weaker signal can connect to a very powerful antenna the antenna creates a connection first then it reads the EEG

  • VinnyMSVinnyMS Canada

    the antenna has to be very powerful to compensate

    You may want to try some practical experience with any EEG equipment you can get your hands on. That is the only way you will understand what EEG is and is capable of. Starting with the Wikipedia article link above, would be good initial reading.

    the antenna has to emit powerfully to connect to the brain, even if EEG is weak it can connect.

    Do you have any experience with radio technology, such as transmitters and receivers? What you say above makes no sense in the context of electrical engineering understanding of wireless transmission. Regardless of how 'powerful' a receiving antenna is, it cannot pull a signal out of the noise, if the signal is too weak. EEG is too weak to travel beyond the scalp.

    I'm not sure why you are posting here on the OpenBCI Forum, but most are posting here with questions about their equipment.

    in theory is the there are many natural sources of brain waves. We can figure out how to electronically generate brain waves using electric currents. Two components are required for brain wave communication: a transmitter and a receiver.

    Brain wave transmitters
    A brain wave transmitter consists of several elements that work together to generate brain waves that contain useful information such as brain wave data.

    Power supply: Provides the necessary electrical power to operate the transmitter.

    Oscillator: Creates alternating current at the frequency on which the transmitter will transmit. The oscillator usually generates a sine wave, which is referred to as a transporter wave.

    Modulator: Adds useful information to the transporter wave. There are two main ways to add this information. The first, called wave strength modulation, makes slight increases or decreases to the intensity of the carrier wave. The second, called frequency modulation, makes slight increases or decreases the frequency of the transporter wave.

    Amplifier: Amplifies the modulated transporter wave to increase its power. The more powerful the amplifier, the more powerful the broadcast.

    Antenna: Converts the amplified signal to brain waves.

    Brain wave receivers
    Brain wave receiver is the opposite of a brain wave transmitter. It uses an antenna to capture brain waves, processes those waves to extract only those waves that are transmitted at the desired frequency, extracts the brain wave signals that were added to those waves, amplifies the brain wave signals, and finally records them on a computer as a raw data file.

    Antenna: Captures the brain waves. Typically, the antenna is simply like diy Wi-Fi antenna. When this antenna is exposed to Brain waves, the waves induce a very small alternating current in the antenna.

    Brain wave amplifier: A sensitive amplifier that amplifies the very weak brain wave frequency brain wave signal from the antenna so that the signal can be processed by the tuner.

    Tuner: A circuit that can extract signals of a particular frequency from a mix of signals of different frequencies. On its own, the antenna captures brain waves of all frequencies and sends them to the Brain wave amplifier, which dutifully amplifies them all.

    Unless you want to record every brain wave type at the same time, you need a circuit that can pick out just the signals for the brain wave type you want to record. That’s the role of the tuner.

    Detector: Responsible for separating the brain wave information from the transporter wave. For brain wave signals, this can be done with a diode that just rectifies the alternating current signal. What’s left after the diode has its way with the alternating current signal is a direct current signal that can be fed to an brain wave amplifier circuit.

    You are describing the basic elements of radio transmission / reception. OpenBCI boards already do all of this. Both the Cyton and Ganglion boards contain wireless transmitters, that mate with a dongle on the laptop that receives the radio packets.

    where can i find that?

    i want to buy

  • VinnyMSVinnyMS Canada

    can a wifi antenna raise the distance between sensors you wear on your head to the laptop receiving it

  • VinnyMSVinnyMS Canada

    how to raise the distance limit? pc to sensor worn

  • wjcroftwjcroft Mount Shasta, CA

    Generally the distance range between the Ganglion or Cyton, and the dongle on the laptop is quite adequate for normal usage. Since these are using Bluetooth 4 transmission, that is the range that applies.

    https://www.google.com/search?q=bluetooth+4+maximum+distance

    Very few people use these where the laptop is outside of the room in which the Cyton or Ganglion is located. Bluetooth range is reduced when passing through walls.

  • VinnyMSVinnyMS Canada

    Can a Wi-Fi antenna be connected to the dongle to raise the distance limit

    Like weld it to the Wi-Fi antenna and attach it together

  • wjcroftwjcroft Mount Shasta, CA

    100 meters (above link) is the length of a football field. In general, when using EEG equipment, you want the laptop to be within easy reach of the person from whom you are gathering the EEG. Because the laptop is used for recording or for BCI Brain Computer Interface applications where the EEG is controlling some process.

    The Ganglion or Cyton boards already have optimal antennas and transmit power for Bluetooth. No external antenna would increase distance. Such external antennas are also generally 'directional', they must be carefully aimed. In this application you instead want an omni-directional transmit pattern.

    Very good, thanks a lot
