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.
