Outline of Final Research Achievements

We achieved (1) the improvement of performance of implantable devices, (2) bidirectional communication with neural networks, and (3) the establishment of out-body communication method. In high performance of implantable devices, an ultra-thin device with low-induced damage are developed and fabricated. The both functions of imaging and optical stimulation are integrated on a device and demonstrated a bidirectional communication with neural cells. In addition, we achieved optical measurement and stimulation in multiple points. Out-body communication is demonstrated in wireless manner and also demonstrated a method to transmit image data effectively.
