Safety / before acquisition

The first protocolis safety.

PiEEG devices are research and educational instruments, not medical devices. Read the electrical, contact, data, and intended-use limits before connecting electrodes.

01 / POWER

Use battery power and isolate the device from mains while connected to a human subject.

02 / INTENDED USE

Research, education, prototyping, and DIY work—not diagnosis, treatment, or clinical use.

03 / RESPONSIBILITY

The user is responsible for safe operation, consent, data protection, and local compliance.

PIEEG / LIABILITY STATEMENT / LAST UPDATED JANUARY 2026

Intended use

PiEEG devices are intended for educational purposes, research applications, hobby and DIY projects, brain-computer-interface development, learning neuroscience, prototyping, and experimentation.

Not intended for

  • Medical diagnosis or treatment
  • Clinical applications
  • Life-support systems
  • Safety-critical applications

User responsibility

By purchasing and using a PiEEG device, you acknowledge that you are responsible for the decision to use it, for operating it safely, and for understanding that it is not approved for medical use.

  • Do not use the device for medical diagnosis or treatment.
  • Assess and accept the risks associated with the experiment.
  • Stop the experiment when safe operation cannot be confirmed.

Safety precautions

Critical electrical rules

  • Never connect PiEEG devices to mains power while they are being used with human subjects.
  • Always use battery power while measuring human biosignals.
  • If you have a pacemaker or another implanted medical device, do not use the equipment without first consulting a physician.

Discontinue use if discomfort occurs. Keep equipment away from water and moisture. Do not modify electrical-isolation circuitry. Follow appropriate electrode-placement and skin-preparation procedures, and inspect the equipment before each use.

Electrodes and skin contact

  • Use recommended, compatible electrodes.
  • Follow appropriate skin-preparation guidance.
  • Discontinue use if skin irritation occurs.
  • Clean and disinfect reusable electrodes between users.
  • Replace electrodes according to their instructions.

Data privacy

Users are responsible for protecting collected biosignal data. Obtain informed consent before recording another person and implement appropriate data-security measures. Follow the data-protection and research requirements that apply in your location and context.

Disclaimer of warranties

PiEEG devices are provided “AS IS” without warranty of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement.

Limitation of liability

In no event shall PiEEG, its developers, manufacturers, or distributors be liable for direct, indirect, incidental, consequential, or punitive damages arising from the use or inability to use PiEEG devices, even if advised of the possibility of those damages.

Regulatory compliance

Users are responsible for compliance with applicable electrical-safety standards, data-protection laws, research-ethics requirements, human-subject protocols, and biosignal-recording regulations.

Questions / concerns

Do not guess
about safety.

If the setup, isolation, electrode contact, or intended use is unclear, stop and ask before continuing.
