A STUDY ON MULTI-AXIS FORCE MEASUREMENT OF POLYMER SKINS USING FBG SENSOR

摘要

The research related to measure the multi-axial forces such as contact forces and friction forces on the ground has being carried out in the field of tactile sensing devices. The developed tactile sensors could reproduce a human sensation by measuring only contact forces or a slip by lateral forces. Also, they are very expensive and have low durability due to the use of MEMS technologies or the semiconductor sensor. In order to overcome the disadvantages mentioned above, flexible substrates such as silicone and polymers with embedded fiber-type sensors such as piezoelectric sensors or fiber optic sensors have been studied. In particular, FBG sensors, which have several sensing points on one fiber optic sensor, were very efficient for multi-point sensing.
