A medical electrode demonstrates a superior adhesiveness to a patient's skin during medical data acquisition or treatment procedure yet attaining painless electrode removal from the skin when needed. The subject medical electrode is designed with adhesive neutralizer (or remover) solvent fully enveloped in one or several compartments embedded in an adhesive layer of the medical electrode unit. The compartments have a contact with the patient's skin when the electrode is attached thereto. When compressed by a medical personnel, the compartment releases the adhesive remover solvent directly to the skin-adhesive interface, thereby neutralizing (or removing) the adhesive material, thereby easing the electrode removal. The adhesive layer is made from PEO, sodium chloride, and water. The adhesive remover solvent contains isopropyl alcohol. A method of manufacturing the medical electrode is presented. 1. A medical electrode unit attachable to a patient's skin , comprising:an adhesive layer attachable to a patient's skin to maintain said medical electrode unit thereat, forming an adhesive-skin interface,an adhesive remover solvent,at least one compartment filled with said adhesive remover solvent and embedded in said adhesive layer and in close proximity to the patient's skin, said at least one compartment being defined by an impermeable envelope substantially fully surrounding said adhesive remover solvent, wherein, upon application of a force towards said envelope sufficient to break the envelope, said adhesive remover solvent passes directly to said adhesive-skin interface, thereby facilitating said medical electrode removal from the patient's skin.2. The medical electrode of claim 1 , wherein said adhesive layer is an electrically conductive hydrogel.3. The medical electrode of claim 1 , wherein said adhesive layer contains 6%-10 weight % of polyethylene oxide (PEO) claim 1 , 5%-8 weight % of sodium chloride claim 1 , and 80%-90 weight % of water.4. The medical ...
