E-2-3 マイクロ3軸力センサによる踵の高さの違いと足底応力の変化計測

抄録

In this study, we fabricated the triaxial force sensors embedded in the shoe insole, and measured the relationships between planter stress and heel height. The size of the micro triaxial force sensors and the prototype triaxial force sensors were 15×15×4.5 mm^3 and 25×25×10 mm^3, respectively. The sensitivities of Z, X, and Y axis force sensor were 0.299 kPa/mV, 0.060 kPa/mV, and 0.063 kPa/mV, respectively. We measured the triaxial force of forefoot and heel on the condition of heel height from 0 to 90 mm. We confirmed that the pressure of the middle part of forefoot and share stress of outside part of forefoot were increase with heel height.
