Description
Additive manufacturing has emerged as a transformative method for fabricating monolithic, assembly-free tactile sensors. However, the operational performance of these sensors depends not only on the intrinsic properties of the base functional materials but also heavily on the structural architecture of the sensors. Modern 3D printing technologies enable precise control over this architecture by allowing adjustments to infill density and geometric infill patterns. This paper presents a review exploring the specific electro-mechanical effects of infill parameters on 3D-printed tactile sensors. We systematically analyze how varying densities across different slicing architectures induce mechanical and electrical modifications in piezoresistive composites and flexible capacitive dielectrics of the tactile sensors.
