Electronic skin are devices that mimic the tactile sensing properties of human skin. They have a variety of exciting applications such as 3D touch screens, wearable electronics for health monitoring, prosthetics, and robotics with human-like functionalities. Herein we propose the use of microporous structures to fabricate 1) highly sensitive, large dynamic range pressure sensors with low hysteresis and 2) strain sensors with no-response to applied pressure. Our pressure and strain sensors can easily be coated onto irregularly shaped 3-dimensional objects (e.g. robotic hand) via spray coating, or be attached to human joints, to detect bending motion. Furthermore, our sensor can differentiate between shear stress and normal pressure. We furthermore demonstrate fiber-based electronic-skin capable of detecting strain and harvesting energy from the surroundings via piezoelectric effect. Lastly, we introduce various strategies to process tactile signals in parallel, inspired from how tactile input is processed in human somatosensory system. These demonstrations make our sensors and signal processing systems highly unique and important for the future development of high performance electronic skin.
