A low temperature sinterable copper nanoparticle or nanowire, comprising gold, zinc, nickel, tin, or aluminum as an alloying metal, and a capping agent. The nanoparticles or nanowires may be deposited on porous or fibrous substrates, the capping agent desorbed, and sintered at low temperature to form conductive traces or sensing elements. The nanoparticles or nanowires may be deposited by aerosol jet, inkjet or dispenser printers, for example.

An ink is provided which can prevent the deformation and degradation of resin products by printed items, and is also suitable for inkjet printing. The oil-based inkjet ink contains a colorant and a fatty acid ester-based solvent represented by general formula (1) shown below and having 12 to 23 carbon atoms in one molecule. ##STR00001##
(In general formula (1), each of R.sup.1 and R.sup.2 independently represents an alkyl group, and at least one of the alkyl groups of R.sup.1 and R.sup.2 is a branched alkyl group having a side chain of at least 4 carbon atoms.).

An ink including a pigment, water, and a resin is provided. An image formed with the ink on a print medium has a tack force of 6 gf or greater but 13 gf or less when measured at a probe temperature of 100 degrees C., where the image is a solid image formed at a resolution of 1,200 dpi, subsequently irradiated with light of 395 nm for 0.6 seconds, and left to stand at normal temperatures and normal humidities for 30 seconds.

A skin printing solution system includes a skin printing device that provides a user with a skin printing solution user interface including an online art gallery, a skin printing server that provides the online art gallery to the skin printing device, and a skin printer that outputs a tattoo image received from the skin printing device to a print region. Herein, when the user selects a tattoo image through the skin printing solution user interface, the skin printing device receives the selected tattoo image from the skin printing server and transmits the received tattoo image to the skin printer. In addition, the online art gallery includes multiple tattoo images, and the print region is the skin of the user or a different user.

The present invention relates to an elastic conductor with high conductivity and stable electrical performance under stretching. The elastic conductor comprises a matrix material; a plurality of electrically conductive structures embedded in the matrix; and one or more particles embedded in the matrix, wherein the particles are configured to release an electrically conductive material upon stretching of the elastic conductor. In a preferred embodiment, each of the particles comprises a core of the electrically conducting material, such as liquid eutectic gallium indium alloy, and an outer shell surrounding the core, such as gallium oxide.
