Artificial flesh is growing ever closer to the real thing. Scientists in Australia have now created a new jelly-like material which they claim has the strength and durability of actual skin, ligaments, or even bone. 人造皮肤越来越像真的皮肤了。澳大利亚的科学家最近发明了一种新型果冻状材料，他们表示，这种材料具有真正的皮肤、韧带甚至骨骼的强度和耐用性。 "With the special chemistry we've engineered in the hydrogel, it can repair itself after it has been broken like human skin can," explains chemist Luke Connal from the Australian National University. 澳大利亚国立大学化学家卢克·康纳尔解释道：“我们研发的这种水凝胶拥有特殊的化学性质，它就像人类的皮肤那样，在受损后可以自行修复。” "Hydrogels are usually weak, but our material is so strong it could easily lift very heavy objects and can change its shape like human muscles do." “水凝胶通常是很脆弱的，但我们研发的这种材料很强大，它可以轻松地举起特别重的物体，而且可以像人类的肌肉那样改变形状。” Having a squishy material with such remarkable properties could be huge for the development of next-generation soft robotics and biomedical devices. Creating a shape-changing hydrogel that has multiple functions has proved an ongoing challenge for scientists, even with natural inspiration from jellyfish, sea cucumbers, and Venus fly traps. |
