如果体表的健康手环能直接给体内的微型植入物“发指令”,按需触发神经刺激或释放药物,许多慢性病的治疗将迎来变革。佐治亚理工学院的Alex Abramson与Ramy Ghanim团队联合麻省理工学院等机构,推出智能无线自主组网系统(SWANS)。该系统巧妙地把人体组织本身当作“通信线”,让体表可穿戴传感器与毫米级可注射植入物实现了跨部位无线协同。2026年9月24日,相关成果发表于《Science》。

    如果体表的健康手环能直接给体内的微型植入物“发指令”,按需触发神经刺激或释放药物,许多慢性病的治疗将迎来变革。佐治亚理工学院的Alex Abramson与Ramy Ghanim团队联合麻省理工学院等机构,推出智能无线自主组网系统(SWANS)。该系统巧妙地把人体组织本身当作“通信线”,让体表可穿戴传感器与毫米级可注射植入物实现了跨部位无线协同。2026年9月24日,相关成果发表于《Science》。

    如果体表的健康手环能直接给体内的微型植入物“发指令”,按需触发神经刺激或释放药物,许多慢性病的治疗将迎来变革。佐治亚理工学院的Alex Abramson与Ramy Ghanim团队联合麻省理工学院等机构,推出智能无线自主组网系统(SWANS)。该系统巧妙地把人体组织本身当作“通信线”,让体表可穿戴传感器与毫米级可注射植入物实现了跨部位无线协同。2026年9月24日,相关成果发表于《Science》。
    在生物电子医学中,如何让分散在身体各处的器件高效联动是一大难题。传统蓝牙或近场通信(NFC)所使用的无线电波极易被含水丰富的人体组织吸收衰减,而且通信模块需要配备较大尺寸的天线和电池,直接卡住了毫米级植入物小型化与长续航的脖子;若在体内铺设实体导线,又会带来额外的手术创伤与感染风险。
    研究团队从人体神经系统的电信号传递中获得启发,利用生物组织天然的离子导电特性,在组织通道内发送特定电压和脉宽的低频电脉冲。接收端依靠特制的晶体管电路识别脉冲特征,只有“对上暗号”的目标植入物才会被精准唤醒,从而在同一组织通道内实现多器件独立寻址。由于植入端采用无源监听设计,待机时几乎不耗电,器件尺寸得以缩小至3 mm以内,直接通过普通注射器针头即可植入;按每天触发一次计算,单次植入可持续工作约1年。
    实验数据显示,这种组织通信信号可穿透超过30 cm厚的生物组织,有效覆盖范围达到传统蓝牙的10倍以上,且微弱脉冲不会损伤周围组织。在大鼠在体实验中,绑在前肢上的穿戴式传感器捕捉到迈步动作后,信号瞬间经身体组织传至后肢的植入式神经接口,精准触发后腿肌肉收缩,完成了“前肢感知、后肢响应”的闭环运动控制。
    “我们的最终目标是实现人类健康的完全自动化——能够随时随地在身体需要的部位精准实施相应治疗,而且整个过程需要以协调一致的方式来进行。”Abramson说道。
