Abstract: An embodiment includes a bioelectrode including a hydrogel film, a conductive film, and a protective film. The conductive film is formed on one surface of the hydrogel film, and the protective film is formed on the other surface of the hydrogel film. The hydrogel film is comprises a mixture of a first material and a second material and is compatible with a living body, the first material configured to cause a sol-gel change at a temperature within a predetermined range around a body temperature of the living body and being compatible with the living body, the second material configured to not cause a sol-gel change at the temperature and being compatible with the living body. The protective film is provided to suppress the infiltration of water into the hydrogel film. The protective film can be made of a waterproof material or a water-repellent material.

Abstract: An acquisition device acquires peak-like shape data measured by a measurement method capable of obtaining waveform data having a peak indicating a feature of a measurement object as a measurement result. An arithmetic device reconstructs the peak-like shape data by using a part of a plurality of bases obtained by performing the Karuhunen-Loeve transform on the peak-like shape data. The arithmetic device reconstructs the peak-like shape data by using a first base, a second base, a third base, and a fourth base obtained by performing the Karuhunen-Loeve transform on the peak-like shape data.

Abstract: A particle sorting apparatus for separating particles according to the sizes of the particles, and includes a microchannel device, a computation unit that determines a condition for controlling the microchannel device using a trained model obtained through machine learning of control condition data and separation result data that have been obtained by separating particles while controlling the microchannel device, and a control unit that controls the microchannel device based on the condition.

Abstract: An embodiment includes a materials development support apparatus including an input data acquisition device configured to acquire input data including a material of a base forming a thin film and a function of the thin film, a candidate data generator configured to provide a preset verification target material as an input to a first learning, output a plurality of candidates for a function provided by the verification target material, an inverse analyzer configured to select a material that provides the function of the thin film included in the input data from the plurality of candidates for the function included in the candidate data, provide the material of the base included in the input data and the selected material as inputs to a second learning model, output a candidate for structure of the thin film, and a presenter configured to present the candidate for the structure of the thin film output.

Abstract: In a flow channel in a measurement region, there are placed a first working electrode, a second working electrode, a third working electrode, a counter electrode, and a reference electrode. The first working electrode, the second working electrode, and the third working electrode are made of a metal such as gold and are formed on a first wall surface of the flow channel. The counter electrode is formed on a second wall surface of the flow channel that faces the first wall surface. The reference electrode is placed on the second wall surface, not in contact with the first working electrode, the second working electrode, and the third working electrode. Surface plasmon resonance measurement is performed at the first working electrode, the second working electrode, and the third working electrode.
