  1. 6. Stretchable electronics using wood-based functional materials

    Författare :Mohsen Mohammadi; Klas Tybrandt; Magnus Berggren; Martin Kaltenbrunner; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stretchable electronics; Wood-based functional materials; Cellulose nanofibrils; Lignosulfonate; Sustainable electronics;

    Sammanfattning : Stretchable electronics allows for direct integration into deforming systems like clothing, skin, and tissue, thereby enabling novel applications in soft robotics, wearable electronics, health monitoring, therapeutics, and human-machine interfaces. However, achieving seamless integration with the human body poses significant challenges, necessitating the development of functional materials with a low Young’s modulus matching biological tissues to avoid any discomfort or immune response.

  3. 7. Reverse Logistics Systems : an Interorganisational Perspective, Focusing on Paper Recycling

    Författare :Maria Huge-Brodin; Sten Wandel; Helén Anderson; Susanne Hertz; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reverse Logistics; Recycling; Paper; Interorganisational; Case studies;

    Sammanfattning : The purpose of the study is to describe and analyse reverse logistics systems. The study is a qualitative case study, and the main case comprise three actors: a supplier of recycled paper; their customer, the paper mill, and the transport provider linking the customer and supplier. Reference cases are recycling electronics and recycling cars. LÄS MER

  4. 8. Hybrid Materials for Wearable Electronics and Electrochemical Systems

    Författare :Mehmet Girayhan Say; Isak Engquist; Magnus Berggren; Shizuo Tokito; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wearables; Green electronics; Organic electronics; Conductive polymers;

    Sammanfattning : Flexible electronic systems such as wearable devices, sensors and electronic skin require power sources and sensing units that are mechanically robust, operational at low bending radius, and environmentally friendly. Recently, there has been an enormous interest in active materials such as thin film semiconductors, conductive polymers, and ion-electron conductors. LÄS MER

  5. 9. Materials Design for Paper Electrodes : A Papermaking Perspective on Electrode Fabrication

    Författare :Patrik Isacsson; Isak Engquist; Magnus Berggren; Nadège Reverdy-Bruas; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Papermaking; Electrodes; Lignin; Nanocarbons; PEDOT:PSS;

    Sammanfattning : The electrification and digitalization of our society has propelled the demand for energy storage solutions. High-end technologies have been developed to satisfy the requirements of demanding applications, such as electromobility and portable consumer electronics, which also increasingly find markets for less demanding applications.
