Recently, a research team from Northwestern Polytechnical University, led by Chang Honglong and Ji Bowen, has achieved a groundbreaking milestone in aerospace engineering. They have successfully developed a three-dimensional conical carbon-based soft cerebral cortex electrode array. This innovative, flexible electrode was transported into space aboard the "Diera No. 5 · China Science and Technology City" space experimental vehicle, signifying the world's inaugural in-orbit wireless implantation and verification of a brain-computer interface (BCI) device. Under the rigorous conditions of space, the electrode demonstrated its capability by continuously and stably collecting brain signals. It gathered crucial data, including noise levels and operational stability, thereby bridging an international technical void. This achievement not only showcases China's prowess in cutting-edge aerospace technology but also paves the way for future advancements in brain-computer interface applications, both in space and on Earth.
