Frequently asked questions

Safety and regulation

Yes, NEMES uses transcranial electrical stimulation at current levels (1-2mA) within established safety guidelines. Our device includes current limiting and overcurrent protection.
NEMES is designed as a wellness device for cognitive training and meditation support and is not intended to diagnose or treat medical conditions.
NEMES delivers 1-2mA of precisely controlled current, the same range used in published studies with excellent safety profiles.
Recommended sessions are 20 minutes, optimized for neuroplasticity enhancement.

Technical and hardware

NEMES combines precise brain stimulation with active cognitive challenges such as math and chess during training.
Yes. Hardware designs, PCB files, schematics, and software will be released under open source licenses.
Chess strategic thinking, mathematical problem solving, attention training tasks, and working memory challenges.
