On the morning of May 25th at 10 o'clock, Professor Liu Jingquan, a distinguished professor at Shanghai Jiao Tong University, presented a report on the research of wearable/implantable MEMS brain computer interface devices. The lecture is hosted by Associate Professor Lu Yipeng from the School of Integrated Circuits. More than 90 people participated both online and offline. Professor Liu gave this lecture on the latest research progress of wearable and implantable brain computer interface devices. He mentioned that this innovative technology brings important opportunities for neuroscience, brain computer interaction, and brain disease research, and is expected to achieve the analysis and regulation of specific neural signals. Furthermore, Professor Liu pointed out that implantable brain computer interface devices are important tools for brain computer interaction and need to be guided according to the needs of neuroscience, brain diseases, and brain computer interaction. This report provides an in-depth understanding of the latest developments in wearable/implantable brain computer interface devices based on MEMS technology. We look forward to the continuous development of this field, making greater contributions to improving human health and promoting brain science research.
