A printed tattoo electrode includes an interconnection unit with a stiff magnetic contact component including one or more attachment magnets configured to magnetically attach the electrode sensor to an external device. A stiff electrical contact component is electrically connected to output interface contacts for coupling electrical signals to the external device. And at least one bridge component is configured to mechanically connect the electrical contact component and the magnetic contact component to the output interface contacts. The bridge component is characterized by a connecting length with gradually varying stiffness so as to distribute mechanical stresses between the electrode sensor and the external device and avoid motion artifacts in the electrical signals.

Various embodiments of the present disclosure are directed to electrode arrangements. In one example electrode arrangement, the arrangement includes an electrically conductive electrode, an electrically conductive thermoadhesive, and an electrode carrier. The electrode carrier is provided in the form of a flat material piece consisting of a textile or non-textile material. The electrode carrier is connected on one side to the electrically conductive electrode and the electrically conductive thermoadhesive being in contact with an opposite side of the electrode carrier. The electrode and the thermoadhesive are electrically conductively connected to form an electrical connection

Provided are mechanisms and processes for enhancing absorption of therapeutic agents into the skin. Therapeutic agents may include lotions, creams, ointments, and solutions. Electrodes are used to apply a voltage to create an electric field to enhance penetration of the agent through the epidermal layer of the skin. The voltage applied may vary between 5V and 36V depending on the skin type or type of substance. The electrodes may be integrated into a wearable device such as a glove, sleeve, mask, bandage, etc.

A shape cutting device of a skin electrode patch includes: a substrate conveyor for transmitting a coated substrate portion and a conductive adhesive portion; a positioning conveyor; a fitted shape cutting module installed in a successive portion of the positioning conveyor and having two pressing wheels and a shape cutting unit, and the two pressing wheels being provided for pressing the coated substrate portion and the conductive adhesive portion, and the shape cutting unit including a roller body with at least one cutting knife which is in a geometrical shape and includes two side cutters and a first-end cutter at an axial end, and opposite ends of the first-end cutter having two second-end cutters, and a gap being formed in the two second-end cutters. The cutting knife has a design that integrates the transmission feature and the efficiency of the whole production line.

The present invention provides a method for treating diabetes and nonalcoholic fatty liver disease (NAFLD), associated condition or disorder thereof, or symptoms thereof suffered by a subject such as a mammal (e.g. a human patient or a pet), comprising (1) placing one or more electrodes within a target blood vessel of the subject and against the target blood vessel wall, wherein the target blood vessel includes the celiac artery and/or a segment of the abdominal aorta terminated at its junction with the celiac artery; (2) adhering a surface electrode on an external surface such as skin of the subject; and (3) releasing a therapeutically effective amount of radiofrequency energy through the one or more electrodes to nearby tissues, so as to increase the temperature of the nearby tissues and induce a thermal alteration of the nearby tissues.

System and methods for providing a patient with arrhythmia treatment are described. For example, a system includes an arrhythmia monitoring and treatment assembly configured to be worn on the torso of the patient. The assembly has a housing discreetly extending from a skin surface of the patient. The assembly is configured to provide therapy on detecting one or more arrhythmia conditions of the patient. A first at least one user response button is disposed on the assembly at a first location on the torso concealed under clothing, and a second at least one user response button is configured to be worn on a second location of the patient's body, a location other than the torso that is accessible to the patient. The system suspends an impending therapy upon receiving a user input from either one of the first or second at least one user response buttons.

Devices, systems and methods are provided for treating post-operative symptoms following major surgery and/or for treating patients in critical or intensive care. A method includes positioning a contact surface of a device in contact with an outer skin surface of patient and applying an electrical impulse transcutaneously from the device through the outer skin surface of the patient to a vagus nerve in the patient for about 60 seconds to about 5 minutes. The electrical impulse is sufficient to modify the vagus nerve such that the symptoms are reduced. A stimulation protocol is provided that includes two or more doses administered per day for a period of time sufficient to relieve the symptoms. The doses may be administered before and after the patient's surgery, or while the patient is being treating in intensive care.
