Electronic skin have a variety of exciting applications such as wearable electronics, prosthetics, and robotics. 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. Together, these devices can be used to differentiate between various tactile inputs with high degree of accuracy. 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. These demonstrations make our sensors highly unique and important for the future development of high performance electronic skin.
