News on October 27, according to Tianjin Daily, a new generation of 8-channel EEG collection domestic chip jointly developed by Haihe Laboratory of Brain-Computer Interaction and Human-Computer Integration and China Electronics Information Industry Group was successfully developed in Tianjin. .

This chip has completely independent intellectual property rights and can be used for non-invasive brain-computer interfaces and multi-modal neuroelectrophysiological equipment. It is widely used in smart medical care, aerospace, human-computer interaction, game entertainment and other scenarios. It will be launched in the sky. Enterprises transform results.

According to reports, the new generation of 8-channel EEG collection domestic chip developed this time adopts a more advanced topology structure than the previous generation. The dynamic range of its analog-to-digital converter has been increased to more than 125 decibels, and the amplifier’s low-noise technology will The input equivalent noise is reduced to less than 0.8 microvolts (peak-to-peak), and low-power design technology reduces single-channel power consumption to less than 4 milliwatts, and has excellent core indicators such as signal-to-noise ratio, power consumption, and input impedance. Significant advantages.

After the chip sample is successfully trial-produced, it will be officially used in self-developed EEG acquisition modules and wearable portable devices, and put into various civilian and special brain-computer interface application scenarios to accelerate the transformation and promotion of subsequent products.

IT Home inquired and learned that the Brain-Computer Interaction and Human-Computer Integration Haihe Laboratory is the sixth Haihe Laboratory in Tianjin. It is led by the Tianjin Municipal Government, led by Tianjin University, and jointly with China Electronics Cloud Computer, Haihe Industry Fund, etc. It was built by more than 10 advantageous units and was officially unveiled on March 27, 2023.
