Abstract
Embodiments relate to methods and systems for monitoring bioelectric potentials. In some instances, an electrode is applied to a patient's skin. The electrode may be at least partly inserted into the patient's skin, such as by inserting at least part of one or more teeth underneath the skin.
Claims13
A biopotential recording system, the system comprising:
- a headpiece comprising a support structure;
- a plurality of electrodes, each of the plurality of electrodes positioned on the support structure, each of the plurality of electrodes comprising a main portion defining a plane, a first leg extending away from the main portion, the first leg having a plurality of first protrusions extending from an end of the first leg opposite of the main portion, and a second leg extending away from the main portion, the second leg having a plurality of second protrusions extending from an end of the second leg opposite of the main portion;
- said first and second legs and said protrusions lying in said plane when in an initial configuration, wherein said legs are configured to bend away from said plane upon application of a force to said electrode from said initial configuration to an attack configuration wherein said legs do not lie in said plane, and to return towards said initial configuration upon release of said force, whereby, when said electrode is placed against skin of a patient, said protrusions insert into said skin of said patient upon said electrode returning from its attack configuration to its initial configuration and secure said electrode to said skin of said patient;
- wherein said electrode comprises shape memory material.
1 more element
An electrode comprising:
- a main portion defining a plane;
- a plurality of legs extending radially from said main portion;
- and
- a plurality of protrusions extending radially from each of said legs, said main portion, said legs and said protrusions lying in said plane when in an initial configuration, wherein said legs are configured to bend away from said plane upon application of a force to said electrode from said initial configuration to an attack configuration wherein said legs do not lie in said plane, and to return towards said initial configuration upon release of said force, whereby, when said electrode is placed against skin of a patient, said protrusions insert into said skin of said patient upon said electrode returning from its attack configuration to its initial configuration and secure said electrode to said skin of said patient;
- wherein said electrode comprises a stainless steel material.
