A monitoring device for monitoring of vital signs of a living organism comprises at least two electrode pins for receiving an electrical activity of the living organism and an optical sensor for sensing a pulse of the living organism, wherein the monitoring device has a compact form and the at least two electrode pins and the optical sensor are integrated in the monitoring device.

A disposable self-powered biomedical sensor comprises a printed wet electrode on a substrate sheet. The wet electrode is provided with an electrolyte element to enhance the electrical contact with a surface to be measured. Moreover, a printed battery encapsulated in a hermetically sealed compartment is provided on the substrate sheet. The disposable self-powered sensor can be stored within an enclosure or a package which provides a proper atmosphere to prevent the drying of the electrolyte and prolong the shelf life of the sensors.

An electrode for use with an implantable medical device includes an alloy and a conductive oxide layer on a surface of the alloy. The alloy includes iridium and at least one of cobalt and iron. The conductive oxide layer includes iridium oxide. The conductive oxide layer has a thickness greater than about 5 nanometers.

An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface and a first location configured to be positioned at the patient's vocal folds. A first electrode is formed on the exterior surface of the endotracheal tube substantially below the first location to receive EMG signals primarily from below the vocal folds. A second electrode is formed on the exterior surface of the endotracheal tube substantially above the first location to receive EMG signals primarily from above the vocal folds. The first and second electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient.

The present invention relates to an electrode comprising a conductive pressure sensitive adhesive layer and a conductive layer. Furthermore, the invention refers to a method of manufacturing the electrode and to the use of the electrode for monitoring biosignals.

Subdermal electroencephalogram (EEG) electrodes are coated to minimize pain and bleeding, and to improve electrical signal transmission.

A novel sweat absorbing textile electrode comprises a textile electrode body and an electrical coupling member, the textile electrode body comprising a conductive foam and a conductive fabric wrapped around the conductive foam, the electrical coupling member being fixed on the conductive fabric; wherein a through hole is provided on the conductive fabric on the side in contact with the human skin. The textile electrode has a light weight, small size and soft texture. It fits on the skin, has good air permeability, and is capable to absorb sweat, which can prevent short circuit between electrodes caused by sweat and be used for collecting bioelectrical signal when sweat comes out from human body. It may also be applied in bioelectrical signal monitoring in high temperature, high humidity environment, and during daily exercise.

Apparatus, methods, and systems for detecting alcohol concentrations of an individual, such as an in vivo alcohol concentrations of an individual. The blood alcohol concentration can be determined based on the peak signal width of the signal received from an analyte sensor.

The present disclosure provides systems, apparatuses, and methods for use of wearable electrode assemblies. The electrode assemblies improve comfort by providing increased overall surface area of their bottom surfaces, which make contact with the patient's scalp and hair. Collapse, compression, or telescoping of the bottom surface will thereby decrease the direct force and/or pressure applied by the distal member or members of the bottom surfaces to the skin. This may be advantageous in patients who have little to no hair in electrode contact areas, patient populations that are particularly skin-sensitive, and/or patients which must wear the electrode assemblies of an extended time period. The electrode assemblies further include structures to dispense and/or maintain conductive gel placed over the patient's skin, thereby maintaining electrical connection quality, and/or to facilitate the clearing of skin and/or hair prior to establishing an electrical connection.

The present disclosure relates to a wearable device with a bridge portion and systems/methods relating to the device. Preferred embodiments may include two flexible wings and a bridge connecting the two wings. In some embodiments, the upper surface of the bridge can be non-adhesive and uncoupled to the flexible wing such that the flexible wing can be decoupled from the bridge when the adhesive is adhered to the surface of a user. The bridge can be narrower in some portions, and extend around the housing of the monitor. The bridge can extend beneath the housing and bisect the two flexible wings.
