   Abstract : The surge in miniaturized electronic components driven by the Internet of Things (IoT) has prompted an interest in non-traditional energy storage solutions. For these applications, reduction of size while preserving power and energy densities are of great importance. READ MORE

5. 3. Hybrid Materials for Wearable Electronics and Electrochemical Systems

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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.
