    Författare :Bei Wang; Klas Hjort; Zhigang Wu; Magnus Berggren; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

  7. 5. Flexible and Cellulose-based Organic Electronics

    Författare :Jesper Edberg; Magnus Berggren; Isak Engquist; Leif Nyholm; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

    Sammanfattning : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. LÄS MER
