1. A device for monitoring a physiological parameter, the device being configured to be adhered to the skin of a subject for the physiological parameter monitoring; the device comprising:
a substrate;
a conductive sensor connected to the substrate, and
a very high tack adhesive attachable to the substrate and the conductive sensor, the adhesive comprising:
a conductive hydrogel adhesive portion and a non-conductive portion, the conductive hydrogel adhesive portion and the non-conductive portion disposed in contact with each other,
the adhesive being:
at least one continuous sheet comprising the non-conductive portion and the non-conductive portion embedded therein:
and the adhesive being defined as:
double-sided defining adhesive material on two sides of the adhesive,
the adhesive defining the non-conductive and conductive hydrogel adhesive portions as an element formed together, wherein the adhesive is formed apart from the substrate and the conductive sensor;
the conductive hydrogel adhesive portion being disposed embedded within the continuous sheet as at least one island within the non-conductive portion of the continuous sheet and being surrounded by the non-conductive portion;
wherein the conductive hydrogel adhesive portion is an inner Layer 4 between Layers 1 , 2 and 3 on one side, and Layers 5 and 6 on the other side;
the conductive hydrogel adhesive portion being disposed to be in conductive communicative contact with and in direct contact with the conductive sensor and being configured to be conductively and securely and directly adhered to the skin and fixed directly to and relative to the skin of the subject for conductive signal communication from the subject to the conductive sensor therethrough; and
thereby being configured to one or both reduce or eliminate sensor movement relative to the skin,
to one or both reduce noise or provide a clean signal.
2. A device according to claim 1 wherein the conductive sensor is configured to receive one or more signals for one or more or all of electrocardiography, photoplethysmography, pulse oximetry, temperature, or subject acceleration.
3. A device according to claim 2 wherein the conductive sensor is an electrode for electrocardiography.
4. A device according to claim 3 wherein the electrode is configured to be a proxy driven-right-leg electrode.
5. A device according to claim 1 comprising
a plurality of conductive sensors connected to the substrate,
the adhesive having a plurality of conductive adhesive portions,
the plurality of conductive adhesive portions being disposed in conductive communicative contact with respective ones of the plurality of conductive sensors, and being adapted to be conductively adhered to the skin of the subject for conductive signal communication from the subject to the conductive sensor.
6. A device according to claim 5 wherein the plurality of conductive sensors include at least one, two or three electrodes for electrocardiography.
7. A device according to claim 6 wherein one of the electrodes is configured to be a proxy driven-right-leg electrode.
8. A device according to claim 1 wherein the conductive hydrogel adhesive portion of the adhesive is embedded within multiple layers.
