Kirigami-inspired solar cells can track the sun without motors
Researchers at the University of Michigan announced on Wednesday that they have developed a method of keeping solar cells turned toward the sun without the need for heavy and energy-hungry motors. Their method is based on the Japanese art of Kirigami -- like origami but with cuts in addition to folds. The team's panel is printed on a flexible kapton substrate which has dash-like cuts running across its surface. When stretched, the panel forms a mesh with each section twisting slightly. The degree of twist, which will allow the panel to follow the path of the sun, depends on how much the panel is stretched. "The design takes what a large tracking solar panel does and condenses it into something that is essentially flat," Aaron Lamoureux, lead author on the paper published in Nature Communications, said in a release.
Nendo's ceramic circuit board speaker gives the rest of the audio world body image issues
We've seen slick hand-crafted ceramic speakers in the past, but this one millimeter-thick collaboration between potter Mitsuke Masagasu and design firm Nendo is in a different league. An entirely different league. The set is result of the so-called Revalue Nippon Project, created by Japanese footballer Nakata Hidetoshi to revive traditional Japanese art forms. Nakata selected five curators -- in this case the director of the 21st Century Museum of Contemporary Art in Kanazaw -- who were then tasked with pairing a ceramicist and designer to collaborate on a one of a kind form. Not satisfied with simply being 31 times thinner than the emaciated Mythos XTR series as a sole basis for artistic impact, the speaker's ravishing circuit design is also made without a human touch. Instead, a computer-controlled process cuts thin slices from a ceramic substrate slab, fixes them with mercury vapor, and then mounts them via a robotic arm. Amazingly, sound quality is still also touted as being top notch. There are no plans however for these speakers to ever be mass produced, so if you were hoping to snag one as the ultimate accessory for your über-modern flat... well, let yourself down easy, alright champ? %Gallery-108170%
