A wearable biological signal measuring element is attached to a garment and detachably connected to a controller, the wearable biological signal measuring element including: an electrode in contact with skin; an electric line connected to the electrode; an electric connector connected to the electric line, penetrating the garment, and detachably connected to the controller outside the garment; and a water supply mechanism including a water guiding mechanism and a first water tank connected to an opening of the water guiding mechanism inside the garment and including a through hole in a contact surface with the electrode.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an Analytics Engine that receives one more signal files that include neural signal data of a user based on voltages detected by one or more electrodes on a set of headphones worn by a user. The Analytics Engine preprocesses the data, extracts features from the received data, and feeds the extracted features into one or more machine learning models to generate determined output that corresponds to at least one of a current mental state of the user and a type of facial gesture performed by the user. The Analytics Engine sends the determined output to a computing device to perform an action based on the determined output.

A signal measurement circuit comprises: a sensor electrode layer connected via a sensor cable to a measurement amplifier circuit; an active shielding layer, which runs along a side of the sensor electrode layer that faces away from the patient; and a first insulating layer that runs between the sensor electrode layer and the active shielding layer. The sensor electrode layer and the active shielding layer are embodied to be electrically conductive.

An integrated differential voltage measuring system for measuring bioelectrical signals of a patient, includes at least two signal measuring circuits, each of the at least two signal measuring circuits including a sensor electrode; a reference measuring circuit comprising a reference electrode; and a shared electrically conductive electrode covering, wherein the electrically conductive electrode covering superimposes at least a region that is formed by the base areas of the sensor electrodes and reference electrode.

A disposable patch electrode structure comprises a front flap and a main structure, which is attached to skin for a bio-signal measurement, the patch electrode structure feeding electrical bio-signals to a bio-signal device separate from the patch electrode structure. The front flap is separated from the main structure by a non-enclosing front flap cut, material of the front flap being thus formed as continuous material of the main structure. Materialistic connection of the continuous material between a rear section of the front flap at a non-enclosing side of the front flap cut and the main structure allows tilt of the front flap with respect to the main structure in response to rise of a frontal section of the front flap with respect to the main structure. The front flap is fully surrounded by the main structure. The front flap comprises contact electrodes at the frontal section, the contact electrodes being both connected with measurement electrodes of the main structure through conductors via the materialistic connection and connectable with counter-electrodes of a connector separate from the patch electrode structure.
