Abstract
Previously reported artificial smart skins for humanoid robots suffer
difficulties in achieving multi-dimensional sensing in a simple
structure with a low system cost. In this paper, we exhibit a
polyimide/copper/PVDF structured smart skin for multidimensional sensing
(including position, proximity, force and humidity), which is enabled by
smart utilization of dielectric property of polyimide layer and
piezoelectric of the PVDF layer. Experimental results demonstrate that
the developed technique successfully obtains large area, flexibility,
and multiple-function with simple device structure and low component
cost, potentially enabling massive production and advanced services for
the humanoid robots’ applications.
