2. 1. Studies of changes in volume in right ventricle with electrical bio impedance

   Author : Karin Järverud; Karolinska Institutet; Karolinska Institutet; []
   Keywords : intracardiac impedance;

   Abstract : In intracardiac impedance, electrical bio-impedance is measured inside the heart. This signal is known to reflect the volume of blood passing in and out of the ventricles. In transthoracic impedance the measurement current and voltage sensing is connected on the subject’s chest. READ MORE

   Abstract : Internet of Things is expanding to the areas such as healthcare, home management, industrial, agriculture, and becoming pervasive in our life, resulting in improved efficiency, accuracy and economic benefits. Smart sensors with embedded interfacing integrated circuits (ICs) are important enablers, hence, variety of smart sensors are required. READ MORE

6. 4. Bio-inspired cellulose nanocomposites and foams based on starch matrix

   Author : Anna Svagan; Lars A. Berglund; Salvatore Iannace; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; starch; cellulose nanofibers; foam; nanocomposites; cushioning materials; biodegradable; expanded polystyrene; mechanical properties; diffusion; Polymer chemistry; Polymerkemi;

   Abstract : In 2007 the production of expanded polystyrene (EPS) in the world was over 4 million tonnes and is expected to grow at 6 percent per year. With the increased concern about environmental protection, alternative biodegradable materials from renewable resources are of interest. READ MORE

7. 5. (Nano)materials for electrochemical sensing applications in different fields

   Author : Nasrin Razmi; Omer Nur; Magnus Willander; Frank Bier; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrochemical bio sensors; Nanomaterials; AuNSs; α-Fe2O3 ZnO nanocomposite; RuO2-Nf pH electrodes; MIP technology;

   Abstract : Health care and the medical industry, environmental monitoring and food sector are just a few examples of human’s major concerns. Design and analytical applications of (bio)sensors and sensing (nano)materials in these fields which have drawn tremendous attention by scientific community, require multidisciplinary knowledge in materials, transducers, and measurement methodologies.
