taximan Posted October 11, 2012 Report Share Posted October 11, 2012 Hiya, Sorry if the title doesn't make sense but I am trying to find some tech I saw a couple of years back,it was a strange looking substance that reacted to voltage by contacting,zero voltage resulted in the material going back to 'normal' state whilst applying small voltages made the material contract. Can anyone point me in the right direction or have any idea wtf I am on about? cheers Paul Quote Link to comment Share on other sites More sharing options...
