In some examples, a medical sensor comprises a containment assembly and an electrode assembly having an electrode well. The containment assembly comprises a deformable housing configured to house an electrically conductive material and being formed with one or more apertures. The container assembly also comprises at least one membrane configured to cover at least one aperture of the one or more apertures to contain the electrically conductive material in the housing. Upon application of a sufficient force to the housing, the housing is configured to assume a deformed state in which the at least one membrane is configured to at least partially uncover the at least one aperture to enable the electrically conductive material to be released from the housing and into the electrode well through the at least one aperture.

An electrode includes a backing. The backing includes a first backing side and a second backing side. The backing has a planar surface and a portion of the backing forms a raised section on the first backing side and an indented section on the second backing side opposite the raised section. The indented section forms a cavity therein. Further, the backing is not electrically conductive. The electrode also includes an electrically conductive gel disposed at least partially within the cavity. The electrode further includes an eyelet penetrating the backing and electrically coupled with the electrically conductive gel. The electrode includes a stud adapted to detachably couple the electrode to a lead wire and configured to attach to the eyelet.

An electrode arrangement measures electric voltages and currents in the human body and provides electro-simulation of the human body. The electrode arrangement contains an electrode array with a flexible support. A number of electrodes are arranged in a grid on the same side of the support and slots are disposed between the individual electrodes starting from the outer edge of the support. An elastic intermediate layer that has one recess for each electrode is provided, each recess defining a cavity to be filled with an electrically conductive gel.
