Randomized trial compares tactile functions of biomimetic and counterfactual skin in robotics, suggesting design implications for sensory technology.

This research aims to investigate how the spatial organization of mechanoreceptors affects tactile functions using a biomimetic robotic skin.
Developed a layered biomimetic robotic skin mimicking human skin features.
Implemented biologically motivated and counterfactual sensory arrangements.
Evaluated performance across passive tactile tasks: detection of contacts, two-point discrimination, and texture identification.
Performance of biologically motivated arrangements was higher than counterfactual configurations across all tasks.
Successfully quantified the impact of spatial organization on tactile function.
Findings enhance understanding of how mechanoreceptor arrangement influences tactile sensitivity.
