TERMINATOR ROBOTS: Scientists develop plastic skin that bleeds red liquid and can even heal itself

(DAILY MAIL) Robots that ‘bleed’ like Arnold Schwarzenegger’s Terminator have come one step closer to reality.
每日郵報)像阿諾舒華辛力加般“流血”的終結者機械人已差一步接近現實。
Scientists have created a plastic ‘skin’ that oozes red blood when cut.
科學家們已創造出一種塑料“皮膚”,當割切時能滲出紅色血液。
It can also ‘heal’ itself, building tiny molecular bridges inside in response to damage.
它亦可以“治愈”自己本身,對回應損壞建立微小分子的內部橋樑。
The red ‘blood’ might sound like a pointless Halloween novelty – but the idea is that the ‘skin’ can warn engineers that a structure such as an aircraft wing has been damaged.
紅色的“血液”可能聽來像是毫無意義的萬聖節新奇 - 但想法是“皮膚”能警告工程師結構例如飛機機翼已被破壞。
The material could provide self-healing surfaces for a multitude of products ranging from mobile phones and laptops to cars, say researchers.
研究人員說,該材料能提供自愈表面功能給眾多的產品,範圍從手機和筆記本電腦至汽車。
When cut, the plastic turns from clear to red along the line of the damage, mimicking what happens to skin.
當切割時,塑料會沿損壞的線從清晰轉為紅色,模仿皮膚所發生的。
It reacts to ordinary light, or changes in temperature or acidity, by mending broken molecular ‘bridges’ to heal itself.
它對普通光線作出反應,且在溫度或酸度發生變化,透過修補爛分子的'橋樑'來自我治愈。
U.S. scientists told how they created the material at the American Chemical Society’s annual meeting in San Diego, California.

Lead researcher Professor Marek Urban, from the University of Southern Mississippi, said: ‘Mother Nature has endowed all kinds of biological systems with the ability to repair themselves.

‘Some we can see, like the skin healing and new bark forming in cuts on a tree trunk. Some are invisible, but help keep us alive and healthy, like the self-repair system that DNA uses to fix genetic damage to genes.

‘Our new plastic tries to mimic nature, issuing a red signal when damaged and then renewing itself when exposed to visible light, temperature or pH changes.’

The material could flag up damage to critical aircraft structures, said Prof Urban. A decision could then be taken whether to replace the component or ‘heal’ it with a burst of intense light.

Scratches on vehicle fenders could be repaired the same way.

Prof Urban’s team is now working on incorporating the technology into plastics that can withstand high temperatures.
