導電性材料を用いた三軸荷重測定用柔軟接触センサの開発(機械力学,計測,自動制御)

抄録

Flexible contact sensor for three-axis load measurement with high load resolution was developed. The developed sensor is composed of skin layer, elastic sphere and load measurement layer. Diameter of elastic sphere is 10mm and the size of developed sensor is 10mm×10mm×10mm. Load measurement layer is composed of upper electrode, PC/VGCF and lower electrode. For the development of high load resolution sensor, PC/VGCF is used for load measurement layer. PC/VGCF is an electric conductive-material dispersed with vapor grown carbon nanofiber (VGCF) and value of resistance of PC/VGCF is changed by load. Therefore, voltage between upper electrode and lower electrode was changed. Normal load, shear load and displacement can be detected by measuring voltage between upper electrode and lower electrode.
