We have developed an intravascular brain-machine interface (BMI) device by combining stretchable structures with flexible, antithrombotic polymer materials. The device features a helical thin-film electrode that can be safely deployed in cerebral veins. To ensure long-term stability in blood-contact environments, we optimized the electrode composition and coating process. In vivo experiments demonstrated continuous, high-quality ECoG signal acquisition for 49 days without thrombosis or signal loss. This work demonstrates the potential of stretchable electronics as a minimally invasive neural interface, highlighting new directions in biomedical applications of flexible devices.
