对用于医疗传感器的可植入微芯片的兴趣正在增加。为了减少植入的侵入性，活体中的无线数据传输是所有此类传感器共有的重要问题。在这里，作者报告了一种用于植入式生物医学传感器芯片的基于光的无线数据传输方法。开发了一种植入式微型图像传感器（400 × 1200 μm2），其设计用于调制具有脉宽调制的小型发光二极管（λ= 855 nm），用于活体内光通信（IOC）。制备了用于IOC的发射器装置和接收器装置，并且成功地展示了通过生物组织（小鼠颅骨）的光学图像数据传输。
Interest in implantable microchips for medical sensors is increasing. To reduce the invasiveness of implantation, wireless data transmission in a living body is an important issue shared by all such sensors. Here, the authors report on a light‐based wireless data transmission method for implantable biomedical sensor chips. An implantable micro‐sized image sensor (400 × 1200 μm2) that was designed to modulate a small light‐emitting diode (λ= 855 nm) with pulse‐width modulation for intra‐vital optical communication (IOC) was developed. Both a transmitter device and a receiver device for IOC were prepared, and optical image data transmission through biological tissue (a mouse skull bone) was successfully demonstrated.
