In recent years, materials scientists and engineers have introduced increasingly sophisticated materials for robotic and prosthetic applications. This includes a wide range of electronic skins, or e-skins, designed to sense the surrounding environment and artificially reproduce the sense of touch.

Researchers at Tsinghua University recently introduced a new dual-modal tactile e-skin that could enhance the sensing capabilities of robots, while also allowing them to communicate information by leveraging a human user’s sense of touch. This e-skin, presented in a paper posted on the preprint server arXiv and accepted by …
