1. Research on development of magnetic field sensor system
We have developed a GMR element combining with even function and achieved the magnetic resistivity change of 5%. We also confirmed that the voltage ratio of 1f/2f was 12.5. In the research of magnetic flux concentration (MFC) structure, we developed the structure using NiFeCuMo material and achieved the evaluation method to measure magnification rate from the maximum slope of magnetic field in MR characteristics. We also proposed amorphous FeSiBNb material and confirmed the magnetic anisotropy in low deposition pressure condition. In addition, we observed magnetic domain in double-layer NiFeCoMo structure in MFC. Modeling with FMEA method in JMAG software was also completed.

2. Research on development of odor sensor system
In the research of device development, we have completed a first version of odor sensing device comprised of a cassette and an amplifier circuit. With this device, we obtained an electrical characteristics of pH response and an interactions between limonene, which is an odor element in citrus group, and a peptide, which we use as a probe on graphene FET. In the research of peptide interface, we have developed an evaluation method to quantify the interaction between peptides and odor molecules using GC-MS, LC-MS and Isothermal titration calorimetry (ITC) methods. As for an establishment of higher sensitivity protocols, the optimization of mixture ratio of organic solvents such as ethanol and dimethyl sulfoxide (DMSO) with water to dissolve limonene was performed.

3. Research on development of module technology
In the research on module fabrication for magnetic sensor and odor sensor, the first design which fulfil the requirement of the sensing characteristics was completed. In order to benchmark the market-put sensors, breakdown studies were performed on several market-put sensors. In the research on system design, a block diagram for each sensor was proposed in the assumption that magnetic field sensor is used for magnetic field microscopy and odor sensor for quarantine inspection. In the research on platform connection, we confirmed our wireless technology can be connected to the edge-platform that practitioner in sub-theme 1 proposes. In the research on module function, a first round of design for high-speed software architecture was completed using 802.11ax, the next generation wireless LAN standard.

4. Human Resources Development Program
We have planned the lecture contents for the next one-year program using the IoT devices.
