Technologies and implementations related to utilizing conductive ink with medical device systems to facilitate electrical contact between an electrode and a person’s skin. The conductive ink may be applied in a variety of manners such as, but not limited to, permanent, semi-permanent, and/or temporary.

A bioelectrode includes an electrode portion that acquires an electric signal of a living body or outputs an electric signal to the living body. The electrode portion is provided with an electrolyte layer that is in close contact with the living body, and is also provided with a sheet-like cover member that covers at least a part or all of the electrolyte layer. The cover member being provided with an opening that penetrates in a thickness direction, thereby discharging moisture accumulated in the electrolyte layer and preventing the swelling and deterioration.

A subcutaneous sensor for use with a continuous glucose monitor includes a reference electrode, a working electrode, and a composition for releasing nitric oxide (NO). The reference electrode includes a reference substrate and an ion limiting layer over the reference substrate. The working electrode includes a conductive substrate, an interference layer over the conductive substrate, an enzyme layer over the interference layer, and a glucose limiting layer. The enzyme layer has an enzyme for reacting with in-vivo glucose in body fluid of a patient. The glucose limiting layer is over the enzyme layer and limits an amount of the in-vivo glucose from the body fluid of the patient that passes to the enzyme layer. The composition for releasing nitric oxide (NO) includes a NO release compound, a hydrophilic material and a hydrophobic material. The composition is on the reference electrode.

A gel distribution apparatus can include modules so that each module is connected to a respective sensor of a sensor array included in headgear. Each module can be configured to facilitate the distribution of a gel onto a scalp of a patient to permit deployment of the gel at locations on the head of a patient near the sensor to which the module is adjacently positioned or attached. The modules can each include at least one flange to permit a user to pull the module away from the scalp while also pressing a compressible gel reservoir of the module toward the scalp for directing the gel onto the scalp. The pulling force can help counteract internal pressure generated from compression of the reservoir to expel the gel so that the gel flows along a desired gel flow path without excessive back pressure.

A chest non-invasive blood pressure detecting probe based on pulse wave transit time and a device thereof are provided. The detecting probe is attached closely to the skin surface of the human chest, and includes a probe body and a patch, which are of split type. The patch is attached and mounted, in a male-female fastener form, on the probe body for use, so that when the patch needs to be replaced, the patch is directly removed and replaced with a new patch, which is convenient for use. The detecting probe is portable and used for continuous dynamic real-time acquiring of the human aortic blood pressure, which is free from the constraints of lead wires, small and comfortable, and high in measuring precision.
