µPatterned electrode

Description

The μPatterned Electrodes, thanks to the combine constructive characteristic, with micrometric inter-electrode distance, allow the delivery of modulating electrical stimulation with a very small extension of the electric field, selectively eliciting a large number of intradermal nociceptive surface fibers (Aδ and C fibers), while at the deeper layers of skin arrive gradients not sufficient to reach the threshold of activation of the Aß fibers[1][2].

This signal can be registered from the scalp using normal subdermal electrodes just like a Pain Related Evoked Potential (PREP).
