Chinese scientists have created a groundbreaking wearable brain monitor, dubbed “Airscope,” claimed to be the world’s smallest of its kind. This wireless device, weighing just one gram, allows for the simultaneous tracking of thousands of neurons. Developed jointly by researchers at Tsinghua University and the Chinese PLA Medical School, the Airscope is significantly lighter than existing technologies. The innovation enables a broader scope of brain activity monitoring in untethered laboratory animals, advancing neuroscience research. Details of the device’s development and capabilities have been published in a recent research paper. This represents a significant step forward in brain-computer interface technology originating from China.
