Array layout for decoupled multimodality. a) Flexible sensor based on CNT/PDMS composites to measure 3D force. Reproduced with permission.[ 65 ] Copyright 2018, Springer Nature. i) Sensor in an exploded view and its demonstration to measure ii) pressure alone or iii,iv) shear forces in the x‐ or y‐axis with the pressure. b) Flexible capacitive sensor to measure pressure and shear forces.[ 68 ] i) Schematic diagram, ii) layout, and its sensing principles for detecting shear (iii) and normal forces (iv). c) Bioinspired capacitive E‐skin to monitor the direction of force. Reproduced with permission.[ 69 ] Copyright 2018, The American Association for the Advancement of Science. i) Optical image and ii) sensor placement of the E‐skin. Color maps show the real‐time discrimination of iii) normal force only, iv) shear force only, and v) combined normal and shear forces. d) Mirror‐stacked layer designed for decoupling bending from other stimuli such as temperature. Reproduced with permission.[ 70 ] Copyright 2019, American Chemical Society. i) Schematic diagram of the sensor with ii) increased or iii) decreased length (and resistance) in the upper or lower part for iv) canceling the effect of bending.
