Open Hardware and Benchmarking

OpenBCI adapter、放大器比较、continuous speech AAD 和高采样 wireless cEEGrid 硬件。

这一组解决什么问题

这一组直接服务自研硬件：OpenBCI adapter、低成本/高端放大器比较、continuous speech AAD 和高采样无线硬件。

组内关系

Knierim 2022 给 adapter/BOM/外壳路线，Knierim 2023 给 Smarting vs OpenBCI 的时序和任务比较，Van Den Broucke 2023 指向 ABR 所需的高采样前端。

对自研的启发

如果要自研或低成本复现，必须把 timing test、channel map、reference/ground、输入噪声和任务基线写清楚。
