Left-ear tVNS
Both configurations are designed around left-ear transcutaneous vagus nerve stimulation. Exact placement, use instructions, stimulation parameters, and permitted ranges have not been published.
TECHNOLOGY
A standalone architecture with defined roles.
The current platform design separates user-interface functions from stimulation safety-control functions. The details below describe design intent, not completed performance verification.
Right-ear PPG on B
NeuroThaw B adds right-ear photoplethysmography for informational monitoring. PPG is not designed to automatically adjust stimulation, and HRV analytics are not a current confirmed feature.
Monitoring requirements
Current, voltage, and impedance monitoring are included in the platform design requirements. This statement does not claim that safety performance or regulatory verification is complete.
