A new generation of domestic chip for brain-computer interface acquisition has been successfully developed in Tianjin.

Thanks to CTOnews.com netizen Xiao Zhan for the clue delivery! CTOnews.com, October 27, according to Tianjin Daily, recently, a new generation of 8-channel EEG acquisition domestic chip jointly developed by brain-computer interaction and human-computer integration Haihe Laboratory and China Electronic Information Industry Group has been successfully developed in Tianjin.

The chip has completely independent intellectual property rights, can be oriented to non-invasive brain-computer interface and multimodal neuroelectrophysiological equipment, and is widely used in intelligent medical treatment, aerospace, human-computer interaction, game entertainment and other scenarios.

According to the report, the new generation of 8-channel EEG acquisition domestic chip developed this time adopts a more advanced topology than the previous generation, and the dynamic range of its analog-to-digital converter is increased to more than 125 decibels. The amplifier low noise technology reduces the input equivalent noise to less than 0.8 microvolts (peak to peak), and the low power design technology reduces the power consumption of a single channel to less than 4 milliwatts. And it has significant advantages in core indicators such as signal-to-noise ratio, power consumption, input impedance and so on.

After the successful trial production of the chip sample, it will be formally applied to the self-developed EEG acquisition module and wearable portable equipment, and put into all kinds of civil and special brain-computer interface application scenarios to speed up the transformation and promotion of subsequent products.

According to CTOnews.com query, Haihe Laboratory of brain-computer interaction and Human-computer Integration is the sixth Haihe Laboratory in Tianjin, led by Tianjin Municipal Government and led by Tianjin University, jointly built by more than 10 superior units, including CET Yunnao and Haihe Industrial Fund, and was officially unveiled on March 27, 2023.
