“江奈挠脚心丨ⅴk”南开大学团队介入江奈挠脚心丨ⅴk式脑机接口项目荣获中国国际大学生创新大赛金奖

  中新江奈挠脚心丨ⅴk网天津11月1日电 (记者江奈挠脚心丨ⅴk 孙玲玲)日前,中国国际大学生创新大赛(2024)总决赛日前在上海落幕,由南开大学人工智能学院、医学院本硕博学生共同组成的“‘灵犀意通’介入式脑机接口”项目团队从全球153个国家和地区、5406所学校的514万个项目中脱颖而出一举摘得金奖。

  团队负责人王文智说,脑机接口是人工智能未来发展的重要方向之一。传统侵入式脑机接口手术伤害高,非侵入式脑机接口信号精度低,而介入式脑机接口可实现安全、高效、持续地采集脑电信号。当前国内介入式脑机接口存在三大难点:电极支架难以精准到达指定脑区;传统尺寸电极无法安全通过脑血管回路;体内留置电源存在巨大安全隐患,且支架无法安全取出。

  团队锚定脑机接口技术,在国内首创支架全程显影技术,规避了血管显影盲区,手术精度提高30%。据介绍,这项技术就像在血管内安装了北斗导航,使手术定位更准,效率更高,打破了国外技术封锁。

  据介绍,团队研制了全球最小的颅内脑电传感器,厚度仅为头发丝直径的1/6,通过细小到几乎没有触感的厚度,在直径最小为2mm的脑血管内采集信号,破解了核心传感器件的核心技术难题。

  团队全球首创无线传输系统。通过体外供能规避了电池发热、漏液对人体的伤害,实现了高频信号传输和支架3个月内可安全取出,具备高可靠性和高抗扰性,并通过灵长类动物实验证明了技术的可行性、精准性与安全性,也标志着该技术向人体临床应用迈出了一大步。目前已完成动物试验并取得安全性报告,团队正与多所知名医院合作,推进人体试验,预计三年内实现临床应用。(完)
