Unique structure of elephant whiskers give them built-in sensing “intelligence”
Summary
A Science study reveals that elephant trunk whiskers have a thick, blade-like, porous structure with a stiffness gradient from base to tip, enabling heightened tactile sensitivity. Researchers demonstrated that the gradient acts as a built-in sensing map, which could inspire bio-inspired tactile sensors for robotics and intelligent materials. The work combines imaging, mechanical testing, and 3D-printed prototypes, suggesting new avenues for artificial whiskers in engineered systems.
