Non-Invasive Recording and Stimulation

EEG and EEG+tES

Designed for both high and low impedance surface electrodes, Ripple Neuromed’s EEG Front Ends are suited for any single reference surface recording.

Integrate your standard touchproof electrodes, caps, or nets with any of our Front Ends. If your experiments call for stimulation, our EEG+tES Front End is versatile enough to deliver transcranial (tES), transcutaneous nerve (TENS), or spinal stimulation (TSS).

Features

  • Compatible with any electrode technology, including caps or nets
  • Wearable on a cap or net to achieve the signal quality of active electrodes with the durability and robustness of passive electrodes
  • Compact form factor is ideal for mobile and ambulatory EEG applications

Primary Use Cases

HD EEG | ERP | BCI | Mobile EEG | Sleep Research | Neuromodulation
