Abstract:

A system for electrically stimulating a user comprising: a first housing portion defining an array of openings; an array of permeable bodies with portions exposed through the array of openings and wetted with a solution that facilitates electrical coupling between the system and a body region of the user, wherein each permeable body has a cavity at a proximal portion and a distal portion and is configured to transmit the solution to the body region of the user; a substrate region defining an array of protrusions configured to support the array of permeable bodies and composed of a conductive polymer; and a set of conductors in communication with the substrate region and including a first conductor that provides a first subset of the array of permeable bodies with a first polarity and a second conductor that provides a second subset of the array of permeable bodies with a second polarity.

International Classification:

A61N 1/04
A61B 5/00
A61B 5/0478
A61N 1/36

Abstract:

In an embodiment, an electrical stimulation system can include one or more of an electrode assembly including one or more electrodes and an electronics subsystem. In some variations, each of the one or more electrodes can include a hydrophilic layer and a conductive layer. In some variations, the electronics subsystem can include one or more of a control module, power module, and a stimulus generator. In some variations, the electrical stimulation can further include one or more of an electrical attachment system, mechanical attachment system, head apparel assembly, flexible housing, and/or any other suitable component. The electrical stimulation system functions to apply electrical stimulation but can additionally or alternatively function to measure/and or record one or more biosignals from a user.

Abstract:

A system for providing an electrical interface between a transducer and a transducer support device, the system comprising: a body mounted to the transducer support device, the body comprising an interface-to-transducer coupling region; a interface-to-electronics subsystem coupling region coupled to the body and contiguous with the interface-to-transducer coupling region, the system defining a fluid sealing region surrounding at least one of the interface-to-transducer and the interface-to-electronics subsystem coupling region; the system comprising an operation mode defining a sealed electrical pathway between the transducer and the transducer support device, wherein: the fluid sealing region is coupled to a complementary transducer sealing region, and the elastically deformable coupling region is biased against an electrical contact of the transducer with the fluid sealing region preventing fluid from reaching the electrical contact of the transducer.

A61B 5/00

Abstract:

A system and method for stimulating a user, the system comprising: a set of pads configured at head regions of the user; a band having a first end coupled to a first pad of the set of pads and a second end coupled to a second pad of the set of pads; a bridge coupled the band and to an electrode during use; and a set of links, each link coupled at a first region to an interior portion of its corresponding pad, and coupled at a second region to the bridge, having an elastic modulus above a threshold modulus such that: in a first mode, displacement of the set of pads produces displacement of the electrode away from the head region of the user, and in a second mode, release of the set of pads orients protrusions of the electrode approximately normal to the head region.
