日本工业技术院机械技术研究所最近以特种高分子材料作电气刺激实验,发现其与人类肌肉有同样敏捷的伸缩反应。该所将50毫安(milliampere)的电流通于长20mm,直径4mm的管状高分子材料数秒钟后,即引起伸缩反应。该所认为此种高分子材料可应用于人造肌肉.现时的缺点为伸缩量过小,有待今后继续研究改进。 Japan Institute of Technology Institute of Machinery Technology recently to special polymer materials for electrical stimulation experiments and found that it has the same agile human muscle contraction reaction. The 50 milliampere (milliampere) of the current through the length of 20mm, 4mm diameter tubular polymer material for a few seconds, that is caused by stretching reaction. The institute believes that such a polymer material can be applied to artificial muscles, and the present disadvantage is that the amount of expansion and contraction is too small to be improved in the future.
