Wide Linearity Range and Rapid‐Response Tactile Sensor Inspired by Parallel Structures

Advanced Science, EarlyView.
Inspired by parallel structures, a composite tactile sensor design is proposed using parallel elastomer integration, developing two novel sensors. This strategy optimizes the force‐electric response and viscoelastic hysteresis of the conductive composite, achieving a balanced enhancement of linear sensing range and fast response.

Invariant Neuromorphic Representations of Tactile Stimuli Improve Robustness of a Real‐Time Texture Classification System

Advanced Intelligent Systems, EarlyView.
This work presents a method to create neuron‐like (neuromorphic) spiking representations of texture that are invariant to the scanning speed and contact force applied in the tactile sensing process. In offline and real‐time experiments, these representations improve classification accuracy, computational efficiency, and the ability to identify textures
