Nanotechnology Research Institute, a part of National Institute of Advanced Industrial Science and Technology (AIST) announced on October 14, 2008 that it successfully developed a mobile type of super ink-jet equipment.
According to the released information, the equipment is almost 1/600 in cubicle dimensions of those currently available and is driven at 5V (DC). It is expected that this technology will significantly contributes to reducing energy consumption as well as volumes of ink. Application areas of this technology will vary ranging from electronics manufacturing processes to security fields where high precision printing technology is required.
