PolyU next‑generation all‑acoustics brain-computer interface system showcases at inaugural BIOHK 2026 Brain-Computer Interface Forum

BIOHK 2026, the Hong Kong International Biotechnology Conference and Exhibition, was held from 9 to 12 September at the Hong Kong Convention and Exhibition Centre, launched its inaugural Brain-Computer Interface Forum, bringing together over 20 leading experts from top universities, hospitals, research institutes, technology companies and investment organisations worldwide to explore cutting-edge technological breakthroughs, technology translation and global collaboration.

Prof. SUN Lei, Director of the Research Centre for Non-invasive Brain Computer Interface and Professor of the Department of Biomedical Engineering at PolyU, delivered a keynote presentation titled "All-Acoustic Brain-Computer Interface (aBCI)" and introduced PolyU’s next-generation “transcranial ultrasound neuromodulation”, which enables completely non-invasive, deep-brain, high-precision neural modulation with ultrasound. The team has further developed sonogenetics technology to significantly enhance precision through animal studies.

In addition, the team showcased its innovative Functional Ultrasound System, which transforms conventional large-scale imaging platforms into a miniaturised and integrated solution, paving the way for simultaneous real-time imaging and neuromodulation in future clinical applications.

Beyond keynote presentations, participants engaged in two roundtable discussions focused on neurotechnology innovation, brain-computer interfaces, and regulatory pathways for advanced medical devices, exploring practical routes toward large-scale clinical translation and commercialisation.

As brain-computer interfaces emerge as a strategic frontier for future industries, PolyU has established the Research Centre for Non-Invasive Brain-Computer Interfaces to advance fundamental research and technology translation. By leveraging PolyU's strengths in biomedical engineering, ultrasound technologies, and artificial intelligence, the Center aims to develop internationally competitive innovations that contribute to healthcare advancement and support the development of new quality productive forces.
