HCI meets Material Science

“…In recent years, engineers have looked to the ancient Japanese tradition of origami to inspire the evolution of engineering structures that can be fabricated, assembled, stored and morphed in unique ways [72,177]. The applications of foldable structures are widespread and have been implemented in an array of practical scenarios including in the design and deployment of solar sails [211] and space telescopes [55,249], in sandwich panel cores [66,85], in the folding of sheet metal [53], in packaging and containers [52,251], in robotics [62,89,127,167], biomedical devices [65,122,190] and electronics [80,96,161,218,228,259].…”

Feasibility Study and Modeling of Components for an Informational Space System Based on a Large Diffractive Membrane

“…The US Agency for Defense Advanced Research Projects DARPA is working of the project of a new space telescope with a membrane diffractive optical system. The project is called MOIRE or Membrane Optical Imager for Real-Time Exploitation [1][2][3].…”

“…According to the analysis of the diffractive lens' weight in comparison to the traditional primary telescope lenses presented in [1][2][3], in average diffractive lens is about seven times ligher then a mirror of the same area. The diffractive lens for the SDMOS is estimated to weight 158.5 kg.…”

Design and simulation of origami structures with smooth folds

“…Potential engineering advantages of origamiinspired structures include compact storage/deployment capabilities [6,7], potential for reconfigurability [8][9][10], and reduction in manufacturing complexity [11,12]. Applications of origami-inspired structures include: various space structures [13], electronic components [14], robots [15], shelters [16], biomedical devices [17] and many others [4,18].…”
