To provide a headband capable of correctly placing an electrode on a head of a user, a headband apparatus includes a plurality of headband portions integrally connected and configured to be positioned about a head of a user, wherein at least two headband portions are each configured to be positioned behind an ear.

Headband, headgear, and electroencephalographic apparatus

A biological signal measuring equipment used in a measurement of a biological signal in a head portion, has a jaw contact portion that comes into contact with a forehead; an occiput contact portion that comes into contact with an occiput; and a supporter that is interposed in a front and rear direction of the head portion and is supported by the head portion by using the jaw contact portion and the occiput contact portion as ends. The biological signal measuring equipment performs the measurement in the same manner as the case of measuring a wave motion of a short period, even in the case of measuring the wave motion of a long period generated in a head portion.

Biological signal measuring equipment

A biosignal measurement device is proposed which can improve measurement accuracy without forcing an excessive burden on subjects. A biosignal measurement device used for measurement of a biosignal in a head includes a support that can support the head, and an electrode provided to the support. The electrode has a plurality of teeth each including an annular portion in which a pair of linear members having conductivity are formed in an annular shape, and a rod-like portion in which the pair of linear members are wound in opposite directions and formed in a rod-like shape. The rod-like portion in each of the plurality of teeth is directly or indirectly fixed at one end to the support.

Biosignal measurement device

A nucleic acid amplifier for carrying out a nucleic acid amplification reaction is disclosed. The amplifier includes a plurality of wells configured to carry out the nucleic acid amplification reaction. The amplifier also include a heating unit provided for every well. The amplifier further includes a light source for irradiating excitation light of a specified wavelength to all of the wells. A fluorescence detection unit is provided for every well.

Nucleic acid amplifier

An electroencephalographic headset includes: a supporter that includes expanding and contracting wires each having expansion and contraction properties and is to be attached to a head of a user by expansion and contraction of each of the expanding and contracting wires; and a plurality of electrodes that are provided to the supporter in defined placement.

Electroencephalographic headset

Disclosed herein is a wake-up assisting apparatus including: an electrode which comes into contact with the parietal of the human body; a signal processing part which detects brain waves through the electrode, determines the sleep stage from the thus detected brain waves, and decides the wake-up time according to the sleep stage; and a stimulating part which gives stimuli to the human body at the wake-up time.

Wake-up assisting apparatus and wake-up assisting method

Disclosed is a bioassay method in which, by controlling the electric field formation in the reaction region where an interaction between substances, such as a hybridization, is performed, the efficiency of the interaction can be improved. Also disclosed is a bioassay apparatus in which the method can be favorably carried out. The method includes at least a step of turning on/off the electric field formation by the electric field-forming means E at a predetermined timing.

Bioassay method, bioassay device, and bioassay substrate

Disclosed herein is an auricle-installed device including, a reference electrode to be placed on the ear lobe, a detection electrode to be placed on a surface exposed to bones surrounding the auricle of the ear, and a support body for supporting the reference and detection electrodes.

Auricle-installed device and bio-signal measurement apparatus

Disclosed herein is a method for extracting a biosubstance from a root of a hair, including the step of using as the hair a hair that has pulling force of at least a predetermined reference value to pull out the hair.

Method for extracting a biosubstance from hair and hair sampling device useful in the method

Disclosed herein is a method and apparatus for determining the base sequence of a nucleic acid molecule by cleaving a nucleic acid molecule of interest while controlling the cleavage site, measuring the change in mass which occurs in the nucleic acid molecule after the cleavage step, and acquiring the base information of the cleaved nucleic acid molecule from the data about the change in mass. The method and apparatus are based on the principle which is entirely different from that used for the conventional technique.
