A bio-signal skin contact apparatus comprises a first layer, a second layer with adhesive for a skin contact, and a middle layer that is elastic and located between and in contact with the first layer and the second layer. Each of one or more hole structures comprise a first hole through the first layer, a second hole through the second layer and a third hole through the middle layer. The first, second and third holes of a single hole structure of the at least one hole structure are overlapping. A connector structure is partly within the hole, the connector structure comprising an extension, which extends above the level of the first layer, and a cavity for a sensor within the connector structure. The extension performs a bayonet connection with a counter-connector. The connector structure comprises an aperture through the extension in a level of the middle layer. A compartment is filled with flowable material within the hole structure, the flowable material being in contact with and covered by the first layer. The flowable material flows through the aperture into the cavity for the flowable material to become in contact with both skin and the sensor in response to tightening action of the bayonet connection that causes compression to the bio-signal skin contact apparatus at the connector structure and deformation of the compartment based on elasticity of the middle layer for causing pressure to the flowable material.

An electric apparatus of a bio-signal measurement system comprising a front part and a back part. The front part comprises a compartment at a back side of the front part, the compartment housing the back part when inserted therein. The back part comprises an electric circuit conductors and an extension plate, which extends to the front part within the electric apparatus. The extension plate comprises first electric contacts of the electric circuit conductors, the first electric contacts residing within the front part when the back part is within the compartment, the first electric contacts acting as counter-electrodes or electrodes of a front flap of a disposable patch electrode structure. The electric apparatus receives the front flap of the disposable patch electrode structure into a volume of the front part for forming a contact between the first electric contacts and the electrodes of the front flap. At least one of the back part and the front part comprises resin holes, and the compartment contains resin received through the resin holes, the resin immobilizing the front part and the back part with respect to each other and attaching them together.

Electric apparatus and its manufacturing method

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.

A polymer holder for a biosignal processing device, wherein a wall of the polymer holder forms a pocket, and the wall follows an outer contour of the biosignal processing device. The polymer holder has a first aperture for inserting the biosignal processing device into the pocket and removing the biosignal processing device from the pocket. The polymer holder includes an electrically conductive contact structure, which is in a wired electric contact with electrodes that receive the at least one biosignal, at a rear section opposite to the first aperture, and the electrically conductive contact structure is at least partly attached inside the wall. The electrically conductive contact structure is electrically connected with a counterpart of the biosignal processing device in response to an insert of the biosignal processing device in the pocket.

A base station for an activity monitoring system that facilitates live monitoring of a plurality of individuals. The base station may include a ventilation channel and a heat sink for cooling a control module disposed within the base station. The base station may be water resistant so as to protect the control module from water damage. The base station may also have an egg-shape for facilitating the drainage of water off the base station and to reduce the force of an impact on the base station.
