Advantage:

TGAM is a brainwave sensor ASIC module designed by Neurosky for mass market applications. 

This TGAM module can process and output brainwave frequency spectrum, brainwave signal quality, 

raw brainwave and three Neurosky eSense parameters: concentration, relaxation and such detection. 

The interface with the human body requires only a simple dry contact point, so it can be easily used in toys,

 video games and health equipment, and because of its low energy consumption, it is suitable for use in battery-powered portable consumer products.

Introduction:

The TGAM module contains the TGAT chip. The application of this biosignal sensor chip is revolutionary for many consumer industries.

 Breaking through the inconvenience of using conventional medical wet sensors, the contact between TGAM and the human body only requires a simple dry contact point.

 Its advanced filtering technology can eliminate environmental noise in daily life, allowing the chip to be used in consumer equipment for general users outside the hospital. 

The Mindflex of Mattel, a toy company, was named the World's Best Toy Award by Time Magazine for its use of this chip.

 As the world's first consumer EEG sensor, its circulation has exceeded one million pieces.

Supporting the use of:

Specification requirements for dry contact points:

-It is recommended that the surface area of the contact point with the skin is between 80 square millimeters and 150 square millimeters

-Ag / AgCI, stainless steel, gold or silver (hard materials and gold-plated materials are available)

-The EEG collection point is located above the left or right eye of the forehead

-The ground point and reference point are located behind the ear or clipped to the earlobe

-The pressure of the contact point on the skin is at least 0.8 psi to prevent the contact point from sliding during use

Wire specification requirements for connecting contact points:

-The length is less than 12 inches, the longer it is, the more likely it is to be affected by noise

-The EEG acquisition point and the reference point must be connected with a shielded wire, and the grounding point does not need to be connected with a shielded wire

-The caliber cannot exceed AWG28
