Abstract

Event Abstract Back to Event A Wireless Multichannel Neural Recording system for Implantable Brain-Machine Interfaces Hiroshi Ando1, Kenichi Takizawa1, Takeshi Yoshida1, Kojiro Matsushita1, Masayuki Hirata1 and Takafumi Suzuki1* 1 Osaka University, National Institute of Information and Communications Technology, Japan Simultaneous recording of neural activity at large scale, in the long-term, and with bio-safety can provide essential data. These data can be used to advance technology for brain–machine interfaces in clinical application, and to understand brain function. Therefore, we present a new multichannel neural recording system that can record up to 4096-channel (ch) electrocorticogram data by multiple connections of customized application-specific integrated circuits (ASICs). Recorded data sampled at a rate of 1kS/s are multiplexed with time division via an integrated multiplex board, and in total 51.2 Mbps raw data for 4096 ch are generated. This system has an ultra wideband (UWB) wireless unit for transmitting the recorded neural signals. From preliminary experiments with a human body-equivalent liquid phantom, we confirmed 4096-ch UWB wireless data transmission at 128 Mbps for distances below 20 mm.
