Inspired by the structure and function of fintertip-skin, interlocked microdome arrays are employed for the demonstration of multifunctional electronic skins (e-skins). We show that e-skins possess highly direction-sensitive sensitive detection capability of various mechanical stimuli including normal, shear, stretching, bending, and twisting forces. Ferroelectric interlocked microstructures can detect and discriminate multiple spatio-temporal tactile stimuli including static and dynamic pressure, vibration, and temperature with high sensitivities. Our electronic skins can be used as wearable healthcare monitoring sensors, which distinguish various mechanical stimuli applied in different directions, selectively monitor air flow and vibration stimuli, and sensitively monitor human breathing flows and voice vibrations. In addition, e-skins precisely detect acoustic sounds and discriminate various surface textures. |
