Towards a high-frequency SSVEP-BCI system
Yunnuo Zhang
Published in Undergraduate Thesis, Georgia Institute of Technology, 2025
Summary
A high-frequency SSVEP-based brain-computer interface designed for use outside the lab. It combines dry-contact spring-loaded electrodes with active buffering, an actively driven guard, and a driven-right-leg circuit, plus an LED stimulus flickering above the threshold of visual perception for more comfortable everyday use.
Contrastive Time Series Representation Learning for Neurochemical Concentration Prediction
Na Dai, Abdallah Daha, Joshua Labbe, Zhengxu Tang, Yunnuo Zhang, Jinxing Li
Published in NeurIPS 2025 Workshop on Learning from Time Series for Health, 2025
Summary
A metadata-aware contrastive learning framework for predicting neurochemical concentrations from fast-scan cyclic voltammetry (FSCV). It models batch identity, scan sequence, and scan rate, and uses preference-based ranking losses to learn discriminative voltammetry features, improving accuracy over traditional baselines.

Published in Device, 4(1), 2026
Summary
AdapSkin is a stretchable, bioadhesive conductive-polymer skin interface that adapts to age-related changes in skin such as dryness and wrinkles. By improving skin-electrode contact, it reduces variation in impedance, signal-to-noise ratio, and motion artifacts, yielding higher-quality surface EMG and better machine learning accuracy for neuromuscular assessment.

Published in bioRxiv (preprint), 2026
Summary
A transformer-based decoder trained jointly across six intracortical speech BCI participants outperforms single-user models for every participant, cutting relative word error rate by over 50% on average. A new user can reach under 7% word error rate after finetuning on fewer than 200 sentences.
