    EXPLOTING INK
    for
    over 30 years, Barry Fox has trawled the world’s weird and wonderful
    patent applications, uncovering the most exciting, bizarre or even
    terrifying new ideas. His column, Invention, is exclusively online.
    Scroll down for a roundup of previous Invention articles.
    A very
    unusual ink-jet printer cartridge, containing explosive ink, has been
    patented by Qinetiq, the commercial spin-off of the British Ministry of
    Defence.
    The ink is a mixture of very fine aluminium particles, each 1 micrometre
    in
    diameter, particles of copper oxide 5 micrometres wide, epoxy varnish
    and alcohol. The ink is stable in liquid form, making it safe to print
    onto conventional paper, but forms an explosive fuse once dry.
    An
    engineer can easily sketch out a printable fuse using computer imaging
    software, modifying the delay in milliseconds by changing the length,
    thickness and pattern of the line on the paper.
    The ink can then be
    printed between a small strip of metal and a larger patch of explosive
    ink. Feeding a current through the metal strip makes it hot enough to
    ignite the fuse, which burns until it reaches the explosive patch. This
    explosion can then trigger the detonation of a much larger amount of
    explosives.
    Qinetiq suggests printed fuses could be used for
    precisely controlling fireworks, triggering vehicle air bags or for
    conventional munitions. Ganging hundreds or thousands of fuses together
    could even make a miniature rocket engine capable of precisely
    adjusting the orbital position of a spacecraft, the company says.
