Study on signal characteristic analysis of multi-axis load measurement sensors

摘要

This study suggested a tactile sensor with piezoelectric sensors in a fibrous shape to detect multiaxial loads (vertical load and horizontal load) simultaneously for the skins of unmanned robots. The sensor was designed by finite element analyses. A simple detecting scheme of the multiaxial loads was constructed by lab-scale experiments. Verification tests of the developed tactile sensor confirmed that applied vertical and horizontal loads could be detected with less than 4% error.
