TLDR
In this article, a table-shaped epoxy sensing plate with four legs was built on top of a flexible polymer substrate, which can convert an applied force to a concentrated stress Normal and shear forces can be detected by combining responses from metal strain gauges embedded in the polymer substrate.Abstract:
In this study, we propose an optimal design and new fabrication method for a slim tactile sensor Slim tactile sensor can detect 3-axial forces and has suitable flexibility for intelligent robot fingers To amplify the contact signal, a unique table-shaped structure was attempted A new layer-by-layer fabrication process for polymer micromachining that can make a 3D structure by using a sacrificial layer was proposed A table-shaped epoxy sensing plate with four legs was built on top of a flexible polymer substrate The plate can convert an applied force to a concentrated stress Normal and shear forces can be detected by combining responses from metal strain gauges embedded in the polymer substrate The optimal positions of the strain gauges are determined using the strain distribution obtained from finite element analysisread more
