| Outline of Final Research Achievements |
In this study, for realizing brain-machine interfaces (BMIs) two key technologies are mainly proposed; one is an implantable flexible device combining sensors and antennas made of bio-compatible materials with analog/digital signal processing LSIs for amplification, ADC, wireless powering and communication. The fabricated devices demonstrate that wireless power transfer assuming implanted devices, and neural signal sensing with the combination of flexible electrode device and a custom amplifier chip. The another technology is a multi-channel neural activity analog frontend LSI adopting compressed sensing scheme, resulting in more power efficient sensing LSI for multi-channel sensor application. The fabricated prototype chip achieves 100-ch sensing and data compression, simultaneously. The measurement results show that the power efficiency is almost 10x higher than conventional state-of-the-art designs.
