生物の微小な力を計測するマイクロピッチ格子付きヒアルロン酸を用いた分布力センサの開発

抄録

Recently, there has been growing interests in biomimetics. In order to elucidate the mechanism of insect movement, it is necessary to measure extremely small and distributed force given by insects against the contacting object surface. A distributed force sensor made of transparent flexible film is proposed. Inside the film, grid patterns of microscale pitch are inscribed using MEMS technology. Distributed force can be obtained by observing the deformation of grid pattern. We have detected 0.1 N level distributed force by a device made of PDMS in previous report. In this report, a device made of agar, which have lower Young's modulus is proposed. The device successfully detected distributed force with approximately 10 μN resolution. The force given by a mosquito leg was detected, which was approximately 300, 290 and 430 μN in x, y and z direction, respectively.
