Abstract
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Free-space microink streams are realized by an array of microcapillaries. Ink is ejected from capillaries accelerated by an electric field with low or no back pressure applied. The capillaries are 20 <formula formulatype="inline"> <tex>$\mu\hbox{m}$</tex></formula> in diameter, whereas the microstreams are only a few micrometers thick due to the Taylor cone effect. This method enables one to draw very fine lines down to 1 <formula formulatype="inline"><tex>$\mu\hbox{m}$</tex> </formula> without lithographical techniques. With a pulsed-field application, dotted lines can also be drawn. Direct drawing of both solid and dotted lines has successfully been demonstrated by applying dc and 500-Hz ac fields, respectively. <formula formulatype="inline"><tex> $\hfill$</tex></formula>[2006-0254] </para>
