2. 1. Novel Microfluidic Devices Based on a Thermally Responsive PDMS Composite

   Author : Björn Samel; Göran Stemme; Jörg Kutter; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEMS; microsystem technology; micro total analysis system; lab-on-a-chip; microfluidics; composite actuator; expandable microspheres; PDMS; poly dimethylsiloxane; disposable; wafer bonding; adhesive bonding; PDMS bonding; adhesive PDMS bonding; selective PDMS bonding; microcontact printing; Electrical engineering; Elektroteknik;

   Abstract : The field of micro total analysis systems (μTAS) aims at developments toward miniaturized and fully integrated lab-on-a-chip systems for applications, such as drug screening, drug delivery, cellular assays, protein analysis, genomic analysis and handheld point-of-care diagnostics. Such systems offer to dramatically reduce liquid sample and reagent quantities, increase sensitivity as well as speed of analysis and facilitate portable systems via the integration of components such as pumps, valves, mixers, separation units, reactors and detectors.

4. 2. 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.

5. 3. Computational modelling of structural battery composites

   Author : David Carlstedt; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Analysis FEA ; Multifunctional materials; Carbon fibre composites; Thermo-electro-chemo-mechanical coupling; Li-ion batteries;

   Abstract : Batteries and surrounding structures (e.g. battery modules and packs) in electrical vehicles and devices are often designed in a way that prevents the electro-chemically active part of the battery cells from being exposed to mechanical loads during operation/service. READ MORE

6. 4. Wave-actuated Preform Infiltration Routines in MMC Production

   Author : Lars-Olov Pennander; Industriell Produktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; Magnetostrictive; Vibration; Actuation; Wave; Infiltration; Preform; Metal; Composites; MMC; Materiallära; materialteknik;

   Abstract : The implementation of highly magnetostrictive wave-actuator techniques in preform infiltration processes for metal-matrix composite production is described. Metal matrix materials require additional methods to handle the content, shape and position of the ceramic reinforcements, which are not required for metal alloy casting. READ MORE
