    Hi, Guys

    Many times I have seen the Charge indicators in Duracell battery
    Can any one let me know what material is it and how it works.
     
  2. It's a printed liquid crystal thermochromic ink temperature indicator
    overtop of a printed tapered-width resistor, printed switch(es) and
    printed conductors.


    Best regards,

    I was under the impression that the resistor/conductors were actual
    metal foil, not printed.
    I could of course be completely wrong.
