Abstract
A multielectrode sensor for use in obtaining electrocardiograph measurements of a patient is disclosed. The sensor includes a substrate, at least a portion of the substrate being stretchable, and a plurality of electrodes coupled to the substrate. A distance between at least two of the electrodes is adjustable by stretching the substrate between the at least two electrodes.

A multielectrode sensor for use in obtaining electrocardiograph measurements of a patient, the sensor comprising:
- a substrate, at least a portion of the substrate being stretchable;
- and
- a plurality of electrodes coupled to the substrate, the plurality of electrodes including V1, V2, V3, V4, V5, and V6 electrodes;
- wherein a distance between at least the V1 and V2 electrodes and between the V4 and V5 electrodes is adjustable by stretching the substrate between the V1 and V2 electrodes and between the V4 and V5 electrodes;
- wherein a first thickness of the substrate between the V1 and V2 electrodes is less than or equal to a second thickness of the substrate between the V4 and V5 electrodes such that a first stretchability of the substrate between the V1 and V2 electrodes is greater than or equal to a second stretchability of the substrate between the V4 and V5 electrodes;
- and
- wherein the first thickness is less than a third thickness of the substrate between the V2 and V3 electrodes such that the first stretchability is greater than a third stretchability of the substrate between the V2 and V3 electrodes.
A method of positioning a multielectrode sensor on a patient, the method comprising:
- providing a multielectrode sensor comprising:
- a stretchable substrate and a plurality of electrodes coupled to the substrate, the plurality of electrodes including V1, V2, V3, V4, V5, and V6 electrodes;
- wherein a distance between at least the V1 and V2 electrodes and between the V4 and V5 electrodes is adjustable by stretching the substrate between the V1 and V2 electrodes and between the V4 and V5 electrodes;
- wherein, in an unstretched state, a first thickness of the substrate between the V1 and V2 electrodes is less than or equal to a second thickness of the substrate between the V4 and V5 electrodes such that a first stretchability of the substrate between the V1 and V2 electrodes is greater than or equal to a second stretchability of the substrate between the V4 and V5 electrodes;
- and
- wherein, in the unstretched state, the first thickness is less than a third thickness of the substrate between the V2 and V3 electrodes such that the first stretchability is greater than a third stretchability of the substrate between the V2 and V3 electrodes;
- positioning the V1 electrode on the patient's torso;
- positioning the V2 electrode on the patient's torso;
- positioning the V3 electrode on the patient's torso;
- positioning the V4 electrode on the patient's torso;
- positioning the V5 electrode on the patient's torso;
- and
- positioning the V6 electrode on the patient's torso.
