| 研究実績の概要 |
After conducting literature survey on electrodes to investigate current issues and challenges and on bioelectricity measurements focusing on electrodermal activity-EDA, experiments on multilayer electrospinning with and without the use of masks for a) developing nanofiber interconnected layers with varying density and tunable patterning and b) creating smoother interfaces with nanofibers density gradient were conducted. Furthermore, investigation of versatile ways to deposit patterned electrodes on highly adhesive patches and Skin Potential study with purchased potentiometer set-up were completed, achieving:
a) preliminary measurements for noise and software artifacts assessment,
b) protocol establishment and first series of measurements to several individuals, and
c) comparison between Au nanomesh and conventional gel electrodes.

3: やや遅れている
理由
Slight delays due to underestimated time needed for trainings and other procedures related to integration to the research and everyday life in the lab. The time required to fix some of the specific axis of the research project was also underestimated. Following readjustment and preliminary tests of Skin Potential and patterned nanofiber layers, current focus is on the Joule effect of nanomesh-based electrodes, with purpose to:
a) overcome the interface issues between electrodes-wiring, soft-rigid parts, by using direct and localized bonding by electrodes power-induced Joule heating, and
b) use tunable heating for wearable devices by versatile patterned electrodes
Currently in the process of selecting the most suitable electrical set-up equipment.

| 今後の研究の推進方策 |
Localized bonding by Joule heating to investigate bonding between different types of nanofiber layers and substrates and to characterize physical properties.
For Skin Potential, fabrication of electrodes with interconnected patterned layers, characterization of skin adhesion, electrical properties stability, and simultaneous measurement and comparison with conventional electrodes.
Furthermore, exploration on the efficient attachment-detachment from skin, utilization of patterned electrodes to measure other skin electrical properties (multi-modal monitoring of EDA), and integration of the afore mentioned electrodes in textiles and test the ambulatory and long-term measurement of EDA to be conducted.
