flexsense: a transparent self-sensing deformable surface
Bookmarked 598 weeks ago
we present flexsense a new thin-film transparent sensing surface based on printed piezoelectric sensors which can reconstruct complex deformations without the need for any external sensing such as cameras flexsense provides a fully self-contained setup which improves mobility and is not affected from occlusions using only a sparse set of sensors printed on the periphery of the surface substrate we devise two new algorithms to fully reconstruct the complex deformations of the sheet using only these sparse sensor measurements an evaluation shows that both proposed algorithms are capable of reconstructing complex deformations accurately we demonstrate how flexsense can be used for a variety of 25d interactions including as a transparent cover for tablets where bending can be performed alongside touch to enable magic lens style effects layered input and mode switching as well as the ability to use our device as a high degree-of-freedom input controller for gaming and beyondhttp:researchmicrosoftcom

how deep is the ocean reallydepth of sea

the deep sea or deep layer is the lowest layer in the ocean existing below the thermocline and above the seabed at a depth of 1000 fathoms 1800 m or more little or no light penetrates this part of the ocean and most of the organisms that live there rely for subsistence on falling organic matter produced in the photic zone for this reason scientists once assumed that life would be sparse in the deep ocean but virtually every probe has revealed that on the contrary life is abundant in the deep oceanin 1960 the bathyscaphe trieste descended to the bottom of the mariana trench near guam at 35798 feet or 677 miles 10911 meters the deepest known spot in any ocean if mount everest 8848 metres were submerged there its peak would be more than a mile beneath the surface the trieste was retired and for a while the japanese remote-operated vehicle rov kaik was the only vessel capable of reaching this depth it was lost at sea in 2003 in may and june 2009 the hybrid-rov hrov nereus returned

shape reconfigurable liquid metal
Bookmarked 599 weeks ago
researchers at nc state have developed a new method to control the interfacial energy of a liquid metal via electrochemical deposition or removal of an oxide layer on its surface using 1 voltliquid metals have very large surface tension and therefore typically adopt a spherical shape surfactants like soap can lower the interfacial tension between two dissimilar liquids for example water and oil but have negligible impact on the large interfacial tensions of liquid metal unlike conventional surfactants the approach here can tune the interfacial tension of a metal significantly from 7x that of water to near zero rapidly and reversibly using only modest voltages these properties can be harnessed to induce new electrohydrodynamic phenomena for manipulating liquid metal alloys based on gallium which may enable shape-reconfigurable metallic components in electronic electromagnetic and microfluidic devices without the use of toxic mercury the results also suggest that oxideswhich are ubiquitous on most metals and semiconductorsmay be harnessed to lower interfacial energy between dissimilar materialsthe paper quotgiant and switchable surface activity of liquid metal via surface oxidationquot is published online in proceedings of the national academy for more information visit the website of pnashttp:wwwpnasorgcontentearly201409151412227111fullpdfhtmlthe work was supported by the national science foundationdickey research group: http:wwwchencsuedudickeygroup
