SM>Hi

SM>Please can someone tell me approximately how much  can shape wires
SM>contract (conraction per unit length)  when current is passed through
SM>them and how fast ? I just need a rough idea as I have never used this

SM>Thanks

SM>Saleem
Yes... Biometal or Muscle Wire (brand names) can stretch up to 15% then 
return to normal length when electrical current is passed.  They act quite 
quickly but I don't have figures in front of me.  You can see their 
advertisements in Electronics Now! mag in the classifieds.
