形状记忆合金(SMA)的用途正在向新的领域扩大。最近日本TOKI公司将Ni-Ti基SMA应用于5接点机械手。每个接点装有直径0.15～0.3mm的SMA丝,当高频脉冲电流通过SMA丝时,该丝在50毫秒内收缩成一
The use of shape memory alloys (SMAs) is expanding into new areas. Recently Japan TOKI company Ni-Ti-based SMA applied to the 5-contact robot. Each contact is equipped with a diameter of 0.15 ~ 0.3mm SMA wire, when the high-frequency pulse current through the SMA wire, the wire shrink within 50 milliseconds into a
