天眼查信息显示，近日，华为申请的“一种信号处理方法及相关装置”专利公布。该申请应用于脑机接口（BCI）技术领域，包括：获取第一信号，第一信号为从脑组织中采集的信号，以及获取下游的反馈信号，然后根据反馈信号对第一信号进行处理。该方法通过结合反馈信号，对从脑组织中采集的第一信号进行处理，保障了信号编解码的长期稳定性，避免信号的非平稳性导致信号编解码的长期稳定性下降甚至失效。此前，华为已公布包括控制刺激器的方法、刺激器、脑机接口系统和芯片等多项专利。
脑机接口产业综合性强，由电子技术、医学、计算机3个领域共同发展构成，经过脑电波发现、电极阵列进化、手术机器人、计算机算法等系列进展后开始逐步步入应用普及期。近期脑机接口领域新进展不断，随着AI等技术的加速驱动，脑机接口商业化望再提速，未来市场空间将加速打开。机构预测，2030-2040年脑机接口全球每年的市场规模可能在700亿到2000亿美元之间。
