Arachnids are among the most sensitive creatures on the Earth. Especially, their mechano-sensory system embedded in the crack-shaped slit organ made of stiff exoskeleton over a cuticular pad near leg joints is known to sense a tiny variation of mechanical stress, thereby, serve as an ultra-sensitive vibration sensor. In this talk, we introduce spider inspired mechanosensors having an ultrasensitivity, durability with high signal-to-noise-ratio. [1] The device fabricated on a sheet of plastic is reproducible, mechanically flexible and shape-deformable so that they can be easily mounted on human skin as skin electronic with multi-pixel arrays. The spider inspired sensory system would provide versatile novel applications utilized in ultra-high sensitivity on displacements. Moreover, it will deal with crack geometry dependency [2], enhanced durability using self-healing polymer [3], strain visualization [4], and noise-damping properties.
