Finding Common Ground

“…Besides traditional materials, such as copper or other metal plates, a growing variety of electrode designs have been made from conductive inks and paints as shown in Table 2. Through the use of inkjet printing, electrodes on both, flexible and cuttable substrates can be prototyped [57,58,105,108,141,142]. As an alternative to inkjet printing, vinyl cutters can create customized adhesive electrodes [175] or cut a substrate for composite electrode materials, e.g., conductive tattoos [98].…”

Tactlets

“…At the same time, as printable electronics commonly are very thin and deformable, more demanding geometries and advanced I/O capabilities can be realized. Prior work has demonstrated ap proaches based on printed electronics to equip custom-shaped 3D objects with various types of printed sensors for capturing user input [11,34,44,45,54] and printable output compo nents, including light-emitting displays [35,54] and actuators for shape-change [7,57].However, tactile output was so far left unaddressed. Fab ricating custom interactive objects that include computercontrolled tactile output still relies on manually assembling conventional components [15,36].…”

Foldwatch

“…The paper is actuated with SMAs to achieve dramatic movement, design quidelines are given Folding mechanism based on the in-plane contraction of a sheet of shape memory polymer, four shapes are intruduced Shape-changing fashions to employ pneumatically actuated origami, a pneumatic folding, shape-changing skirt Soft-bodied robotic actuators, combines robotics, folding, and fashion Awakened Apparel (Perovich, Mothersill, & Broutin Farah, 2014) Color-Changing Origami (Kaihou, & Wakita, 2013) Color-changing origami using LEDs Uses thermochromic and conductive ink, it can be folded in the same way as paper origami, it mustn't contain any hard electronic components Figure 2. Foldable device analysis, with prototypes listed in alphabetical order: Awakened Apparel [42]; Bookisheet [61]; Colour-Changing Origami [22]; Flexpad [53]; Foldable Interactive Displays [27]; FoldMe [24]; Gummi [49]; jamSheets [40]; MimicTile [33]; PaperFold [11]; PaperTab [56]; PaperWindows [18]; PrintScreen [39]; Projectagami [55]; Shape Memory Alloy [43]; Self-Folding Origami [57]; Sticky Actuator [36]; Tilt Displays [1]; uniMorph [15]; Xpaaand [25];.…”

“…The next stages for this work would be to further the extendable FoldWatch concept by making a functional prototype for user testing. This could be produced using Smart Material Alloy (SMA) wires such as in the Morphee Couture prototype [47], and combining with thin-film electro-luminescence [39] and Flexy technologies [58] or OLED [26,51] -however, the materials used must make use of full closure [47], i.e. bend completely back on themselves.…”
