The Science of Human Touch, and Why It's so Hard to Replicate in Robots

Robots excel at visual perception but still struggle to replicate the nuanced human sense of touch. Human skin contains multiple mechanoreceptors that detect vibration, stretch, texture, and pressure, and our touch is an active, dynamic process. Soft‑robotics researchers are embedding tactile sensors across entire compliant bodies, enabling local processing that mirrors the distributed intelligence seen in octopus limbs. A new artificial‑skin patient simulator, Mona, demonstrates how tactile feedback can transform occupational‑therapy training and points toward future care robots that safely assist an aging population.
