Abstract: The present invention relates to a physiological recording electrode, and, more particularly, to an EEG (electroencephalography) recording electrode that can be used without the need for numerous steps in preparing the subject's skin and the electrode itself. The invention further relates to a surface feature or penetrator with a size and shape which that will not bend or break, which limits the depth of application, and/or anchors the electrode or other device during normal application; and a packaging system comprising a well and electrolytic fluid for maintaining a coating of said electrolytic fluid on the surface feature or penetrator.

Abstract: Methods, systems, and devices for bioimpedance measurements using a wearable device are described. The method may include generating a first electrical signal using a first electrode of a wearable ring device, and receiving the first electrical signal using a second electrode of the wearable ring device. The first electrode or the second electrode may be disposed within an inner circumferential surface of the wearable ring device. Further, the method may include determining first bioimpedance data associated with a user based on a comparison of the first electrical signal generated by the first electrode and the first electrical signal received by the second electrode, and causing a graphical user interface (GUI) of a user device to display a message associated with the first bioimpedance data.

Abstract: With respect to the methodology of using the Huygens sensing array, the invention includes an improvement in a method of sensing biopotentials in tissue including the steps of: providing a Huygens sensor array; and sensing a native electrical biopotential signal using at least one electrode on a catheter with an amplifier circuit placed on the inner surface of the at least one electrode in the Huygens sensor array to generate a well-formed waveform of the biopotential showing clear electrical properties indicative of the tissue with a SFDR of at least 24.9 dB and SNR of at least −13 dB. In one embodiment the tissue is cardiac tissue and the biopotential signal sensed by the Huygens sensing array is a native cardiac waveform. In one embodiment the sensed biopotential signal is a manifestation of underlying electrochemical activity sensed by the Huygens sensing array of a biological substrate corresponding to the tissue.

Abstract: A method is provided for optimization of a stimulation specificity and an energy consumption of implanted electrodes in excitable tissue of a patient. The method may involve electrically stimulating excitable tissue between one or more combinations of electrode pairs in a cluster of electrodes, or electrically stimulating excitable tissue between one or more combinations of electrode pairs in two or more clusters of electrodes. The two electrodes of the electrode pairs may not belong to a same cluster. Each of the electrodes may be located on a physically separated entity, such that the tissue surrounds and separates each electrode from all other electrodes, thereby allowing tissue between the electrodes to be stimulated. An electrode pair or pairs which give rise to a lowest energy consumption while still giving a therapeutic effect may be chosen. Alternatively, each electrode pair may be assigned a value related to the information provided by the patient and the energy consumption, and the electrode pair or pairs which give(s) rise to a most favorable assigned value may be chosen.

Abstract: The disclosed apparatus comprises an intravascular sheath and dilator that can be placed over a guidewire after percutaneous vascular access. One or more electrodes are positioned axially at or near the distal end of the dilator, facilitating guidance of the sheath to the heart without fluoroscopy (i.e., by using electrical and/or magnetic guidance). The electrodes are in electrical conductance with leads via wires that extending proximally from the electrodes on or through the wall of the dilator or sheath.

Abstract: The measurement of electrodermal activity (EDA) can be facilitated by a sensing surface. The sensing surface can have a plurality of electrode pairs. An electrode pair can include a first electrode and a second electrode that are electrically isolated from each other. The plurality of electrode pairs can be electrically isolated from each other. A distance between neighboring electrode pairs can be larger than a distance between the first electrode and a second electrode of each electrode pair. One or more sensors can be configured to detect contact with the sensing surface. In response to the one or more sensors detecting contact with the sensing surface, one or more electrode pairs can be selected to be activated. In response to the one or more electrode pairs being selected to be activated, the selected one or more electrode pairs can be activated.
