Electrode patch and connection system

A connector device that is portable and allows electrophysiological monitoring via an electrode patch, the connector device comprising or in a form of a first clamping member and a second clamping member that are configured to move between a clamped position in which the first and second clamping members are configured to clamp the electrode patch for monitoring electrical activity generated by a subject or at least a portion of the electrode patch to allow physical and operative connection between the connector device and the electrode patch or the portion of the electrode patch, and a released position in which the first and second clamping members are configured to move away from the clamped position to allow the electrode patch or the portion of the electrode patch to be released from the connector device, wherein the connector device comprises a main body having a planar surface onto which the electrode patch or the portion of the electrode patch is configured to be placed, and wherein the connector device is a wearable electronic device and at least the main body and the first clamping member together form a housing inside which electronic components of the connector device are at least partially disposed, wherein the main body comprises a first end portion and a second end portion that are located opposite to each other, wherein the first clamping member is mounted to the main body at or near the first end portion, and the second clamping member is mounted to the main body at or near the second end portion, wherein in the clamped position the first and second clamping members are each configured to move towards the planar surface and in the released position the first and second clamping members are each configured to move away from the planar surface.
