In this review paper, we focus on the 3D printing technologies that consist of the extruding of fluid material in lines to form structures for electro- and biomechanical applications. Our paper reviews various 3D print technologies, materials, sensing technologies and applications of extrusion-based 3D printing. We also discuss how to overcome some of the challenges with 3D printed sensors, such as the anisotropy of the conductors as well as the drift and nonlinearity of the materials.

A 3D-Printed Soft Fingertip Sensor for Providing Information about Normal and Shear Components of Interaction Forces
TLDR
FEM analysis showed that the output of the sensor is largely related to the sensor geometry and location of the strain gauges, and the conductive TPU that was used has a negative gauge factor for the strain range used in this study and might cause non-linear behaviors in the sensor output. Expand
3D printed capacitive shear and normal force sensor using a highly flexible dielectric

Modelling of Anisotropic Electrical Conduction in Layered Structures 3D-Printed with Fused Deposition Modelling
TLDR
This model can be used to explain the properties of certain 3D-printed sensor structures, like constriction-resistive strain sensors, and conductive behavior between completely isotropic and completely anisotropic can be modeled, depending on the dimensionless properties. Expand
