Dr. Wang’s research group has made a significant contribution to the field of wearable neurotechnology with the publication of a research article in Nature Communications, one of the top journals in the field.
The paper, titled Bioadhesive hydrogel-coupled and miniaturized ultrasound transducer system for long-term, wearable neuromodulation, introduces MiniUlTra. This is a small, wearable ultrasound device designed for safe, non-invasive brain stimulation over extended periods.
The device tackles two key challenges in current neurostimulation tech: bulkiness and short-lived adhesion. It uses a simplified fabrication method to create a compact, self-focusing transducer, paired with a custom bioadhesive hydrogel that is stable over 35 days—far longer than conventional gels.
Using EEG measurements, the team stimulated the brain’s somatosensory cortex and successfully reduced sensory signals, showing reliable performance of the device over 28 days. The hydrogel also maintained strong adhesion and acoustic quality under changing conditions, and the device operated safely within FDA guidelines.
This work from Dr. Wang’s group marks an important advancement in wearable neurotechnology, introducing a compact, non-invasive approach for long-term brain stimulation!
