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.[Nature 516, 222-226, 2014] 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 [Adv. Mater. 28 (37), 8130-8137, 2016], enhanced durability using self-healable material [Nanoscale 10, 4354-4360, 2018], minute strain visualization [Adv. Funct. Mater. 29 (40) 1903360, 2019], and noise reduction [unpublished] for pursuing more practical applications. |
