   Författare :Bei Wang; Klas Hjort; Zhigang Wu; Magnus Berggren; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser patterning; sacrificial mask; liquid metal; strain sensor; skin movement; masking; shrink film; 3D conformal masking; liquid metal particles; soft electronics; stretchable electronics; compliant electronics; skin-like electronics; epidermal electronics; micro-heater; particle sintering; enteroendocrine cells; localized ectopic expression; wettability; flexography printing; conformal transfer printing; hydro printing; plant physiology; drosophila;

   Sammanfattning : Skin-like electronics could provide a soft and gentle contact with living beings for perceiving and delivering the information of pressure, strain, temperature with higher spatial resolution and sensitivity than our skin, without disturbing the user. Gallium-based liquid metal (LM) is an excellent material for soft and stretchable skin-like devices, since it has high electrical and thermal conductivity, flowability, and self-healable capability.

3. 2. Liquid Sensing : Development and Characterisation of an Electronic Tongue Based on Electrochemical Methods

   Författare :Susanne Holmin; Elena Dominguez; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A new sensor technology for liquid sensing is reported, i.e. the electronic tongue based on electrochemical methods. Such a system involves the combination of non-selective sensors (metal electrodes) and a signal processing part. LÄS MER

4. 3. Liquid phase sintering of W-Ni-Fe composites : liquid penetration, agglomerate separation and tungsten particle growth

   Författare :Anders Eliasson; Hasse Fredriksson; Thomas Gomez-Acebo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Liquid phase sintering; heavy metal; particle composites; tungsten; penetration; agglomerate separation; particle interaction; parabolic flight; sounding rockets; microgravity; Kirkendall effect; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). LÄS MER

5. 4. Alkali Metal Stripping and Plating in Liquid Electrolytes
