Velvet worms, also known as peripatus or\u00a0 onychophorans [1<\/strong>],\u00a0 are\u00a0 a\u00a0 phylum\u00a0 of\u00a0 evolutionary\u00a0 importance\u00a0 that\u00a0 has survived all mass extinctions since the Cambrian period. They capture prey with an adhesive net that is formed in a fraction of a second [2<\/strong>]. The same glue that they produce does not produce any effect on their own skin. Furthermore, many onychophorans live in places rainy forests where floodings are quite common, but somehow, they rarely drawn. We have observed that their skin is superhydrophobic and when submerged in water they stay afloat with the help of a super bubble that surrounds their whole body.\u00a0 In this research we will try to mimic this wonderful life vest using soft polymers and will investigates the physical limits of this system.<\/p>\n

IRES student involvement<\/strong><\/p>\n

Students will be trained in the basics of drop formation hydrophobicity and microscopy. They will propose ways to mimic the velvet worm skin with different materials, and will prepare samples to test the effect of microstructure and elasticity on the wetting properties of the artificial Onychophora skin. Measurements of contact angle and droplet impact dynamics will be performed.<\/p>\n
