Abstract:
An electrode sensor attachable to a substrate for sensing electrical activity of a patient, the electrode sensor comprising:an elongated conductive resilient body having first and second ends and a conductive wire, the first end contactable with the patient for sensing electrical activity of the patient, the second end being configured to attach to the substrate; a conductive head connected to the first end of the elongated conductive body so that the head is in conductive communication with the elongated body, the connection of the conductive head to the elongated body defining an inner space within the head and the body, the inner space complementing the shapes of the head and the body, the conductive head being configured to contact the patient for sensing electrical activity and being permeable to allow conductive fluid to be absorbed therethrough; and an absorbent material disposed in the inner space for absorbing fluid applied on the head, the absorbent material being in contact with the conductive head and the elongated body.
