By applying the electricity at different voltages at the bottom and top, the onion skin moved like a real muscle.
科学家们在洋葱皮的底部和顶部施以不同电压的电流,便观察到洋葱皮如同真肌肉那样做伸缩运动了。
At the moment, high voltages need to be used which will be a problem if they are to be implemented in robots and other automated tools.
此刻需要用到高电压,但若是把洋葱皮运用到机器人和其他自动化工具中,这将成为一大问题。
The team behind the discovery, from National Taiwan University, will now look at whether a similar technique using lower voltages is feasible.
做出这一发现的团队来自台湾国立大学(National Taiwan University),他们现在将研究在较低的电压下,类似的技巧是否可行。
Other issues that need to be resolved are making the onion skin more durable and water-resistant.
其他需要解决的问题则是要让洋葱表皮更加持久和防水。
Artificial muscles have been created before using live muscle tissue, but they have to be kept alive - a problem that using vegetable tissue sidesteps.
科学家们在使用活肌肉组织之前便创造了人造肌肉。可是它们必须一直保持活性。使用植物组织恰好回避了这个问题。
