Neuromorphic sensorimotor loop embodied by monolithically integrated, low-voltage, soft e-skin

🤖 Plain-English Summary

Artificial skin that simultaneously mimics sensory feedback and mechanical properties of natural skin holds substantial promise for next-generation robotic and medical devices. With a trilayer, high-permittivity elastomeric dielectric, we achieved a low subthreshold swing comparable to that of polycrystalline silicon transistors, a low operation voltage, low power consumption, and medium-scale circuit integration complexity for stretchable organic devices.

🔑 Key Findings

• However, achieving such a biomimetic system that can seamlessly integrate with the human body remains a challenge.
• Through rational design and engineering of material properties, device structures, and system architectures, we realized a monolithic soft prosthetic electronic skin (e-skin).
• It is capable of multimodal perception, neuromorphic pulse-train signal generation, and closed-loop actuation.
