An electrode apparatus is applicable on a skin with hair of a mammal for measuring an electrical bio-signal. The electrode apparatus comprises cylindrical chambers, each of which comprises a wall, which forms a cavity within the cylindrical chambers, a roof at a first end of each of said cylindrical chambers, a second end of said cylindrical chambers opposite to the first end being open, and at least one electrode. An elongated structure is located within each of the cylindrical chambers, and comprises a first portion parallel to a central axis of a cylindrical chamber within which it is. A first end of the elongated structure, the first end of the elongated structure belonging to the first portion, is attached to the roof. At least one second portion, each comprising a second end opposite to the first end, deviates from a direction of the central axis of a cylindrical chamber within which it is. The elongated structure rotatable in order to bundle hair when applied to the mammal so as to improve a contact of the electrode with the skin of the mammal.

A biological information measuring apparatus includes a cover member and a hardware processor. The cover member is provided with sensors for detecting biological signals to cover a position of a biological part of a subject. The hardware processor is configured to estimate a positional relation of the position of the biological part of the subject with respect to the cover member at a first time point. The hardware processor superimposes first point cloud and second point cloud. The first point cloud is acquired by a non-contact mechanism front the subject at the first time point and represents a surface of the biological part of the subject in a coordinate system of the sensors. The second point cloud is created based on a morphological image of the subject captured by a biological structure acquiring apparatus and represents the surface of the biological part of the subject.

This invention discloses a non-invasive electroencephalography (BEG) signal recorder and a multiband active electrode (MAE) EEG cap array. A narrow-band amplification method is disclosed that divides the desired bandwidth of the input brain signal to smaller bands, each recorded using a separate amplification path. A novel twisted differential feedback topology is disclosed for both amplifiers and active filters having ultra-high input impedance. A one-wire EEG cap array of tightly connected MAEs is disclosed that improves the flexibility and portability of the EEG cap by reducing the number of wires between the EEG cap and the host processor. Due to having MAEs embedded inside electrodes, the output signals of electrodes are digital information. The tightly connected network of MAEs enables the reference electrode to be chosen dynamically. Moreover, the voltage of the reference node is adjusted using a correction feedback loop before each recording step.
