Chinese researchers have developed a multifunctional electrode coating that addresses key challenges in long-term brain-computer interface (BCI) implantation, including signal loss and tissue adhesion, bringing BCI one step closer to clinical application, the Global Times learned from the research team behind the findings on Sunday.
As an emerging field combining neuroscience and artificial intelligence (AI), BCI faces a major challenge of ensuring long-term compatibility between electrodes and brain tissue. Previous clinical trials showed that immune responses could cause implanted electrodes to retract after just three months, severely reducing signal quality and the number of available channels.
This problem stems from chronic inflammation triggered by implants, which creates insulating scar tissue around electrodes and separates them from neurons. Irreversible adhesion between electrodes and brain tissue after long-term implantation also makes device removal risky, potentially causing brain injury during follow-up surgeries.
Experiments showed that flexible neural electrodes coated with this material could operate stably in the brain for more than 300 days and could be safely removed without causing damage. This means the universal coating technology can make electrodes not only operate stably over the long term but can also be safely removed and replaced after aging, paving the way for long-term BCI applications.
Developed by the research team led by Zhang Wei at the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, associated with Beijing Tiantan Hospital, Shanghai Institute of Microsystem and Information Technology and NeuroXess, a high-tech life science company specializing in BCI technologies, the cationic alternating peptide electrode coating preserves electrode flexibility and conductivity, while offering antibacterial, anti-protein adsorption and immune-rejection-inhibiting functions.
A 300-day animal study showed the coating's effectiveness. Bare electrodes experienced a sharp loss of recording capability after 90 days of implantation and could barely detect neuronal signals after 300 days. In contrast, coated electrodes maintained stable recording channels and consistently captured neural signals above 155 microvolts.
In terms of neural modulation, after 300 days of implantation, conventional electrodes required a current of 100 microamps to induce weak limb responses, while coated electrodes triggered clear movements with only 2 microamps, improving modulation efficiency by 50 times.
Notably, the removal tests highlighted a key advantage of the coating that electrodes no longer form irreversible bonds with brain tissue. In the experiments, the coated electrodes were removed intact, with minimal damage to the surrounding brain tissue, Zhang told the Global Times on Sunday.
。优酷索赔1000万元，并要求其通过官方渠道公开道歉。
B | 昨晚，“鞭打公牛”发表了一篇题为“今天的头条新闻已经到达优酷的收购”的文章，称今天的头条新闻已经到达优酷的收购，并且正在与西瓜视频业务对接。优酷回应说：爆炸完全是虚假的胡说八道，严重影响优酷品牌的声誉，优酷将追究相关自媒体传播虚假新闻的法律责任；字节打人副总裁李亮回应说：“新闻不是真的”；阿里大文娱乐称此内容是虚假新闻，R。
C | umor应承担法律责任。去年12月，有传言称字节弹跳（今天的头条新闻和Tremolo母公司）将收购优酷，据报道，字节弹跳（今天的头条新闻和Tremolo母公司）正与阿里巴巴商谈以50亿美元收购优酷和阿里巴巴音乐相关业务。优酷官方微博帖子叫“胡说”！今天的头条新闻也回应说“这个谣言不是真的”。
