This paper introduces a flexible thin-film transistor platform for active neural sensing, demonstrating long-term stability and high channel count scalability in vivo.

This study introduces Adaptive Charge Modulation (ACM) for spinal cord stimulation, achieving focal activation at deep tissue sites with reduced surface activation and muscle co-activation.

The paper introduces a high-channel-count flexible electrode for deep brain recording, capable of capturing single-unit activity from up to 128 channels.

The paper introduces a Brain-iEEG-microdisplay that measures and displays real-time brain activity during surgery, improving precision and efficiency in neurosurgical procedures.
