World's Smallest Non-Invasive Brain-Computer Interface System Launched
Tianjin University and Shenggong Diting have released the 'Shenggong · Xumi · Naolifang', a 3-gram non-invasive brain-computer interface system, described as the world's smallest and lightest.
The Haihe Laboratory for Brain-Computer Interaction and Human-Machine Integration at Tianjin University, in collaboration with Shenggong Diting (Tianjin) Technology Co., Ltd., has officially launched the high-performance non-invasive 'Shenggong · Xumi · Naolifang' system. Weighing just 3 grams and occupying less than 2 cubic centimeters, it is reported as the world's smallest and lightest non-invasive brain-computer interface system to date.
Unlike traditional non-invasive EEG devices such as caps, helmets, or headbands, the 'Shenggong · Xumi · Naolifang' integrates EEG electrodes, circuitry, a battery, and wireless transmission within a miniature space. It is designed to be attached to the scalp using an innovative structure, hidden within the hair, offering a near-imperceptible wear experience due to its minimal weight. This development aims to enable broader applications across medical, consumer, and industrial sectors.
The system's core performance metrics reportedly meet relevant requirements of the Chinese national standard for medical devices, GB 9706.226-2021, enabling precise and stable capture of faint brain signals. Furthermore, at a high sampling rate of 1000Hz, the device offers a battery life of 8 to 10 hours, suitable for continuous brain-computer interaction tasks.
Based on this system, the laboratory team is also working on "building brain-computer interface and intelligent wearable safety management models for personnel in special operations" in guidance from departments managing special operations and emergency response, in partnership with leading companies and academic institutions.
