Electronic skin are devices that mimic the tactile sensing functionalities of human skin, which a wide variety of applications in touch screens, wearable electronics, prosthetic, and robotics. Important characteristics of electronic skin are high sensitivity, large dynamic range, low hysteresis, high spatial and temporal resolution, large area processability, and the ability to differentiate between various tactile inputs. We herein present various materials selection and architectural design principles to tune these properties to achieve high performance electronic skin devices.
