2. 1. Highly-Efficient Energy Harvesting Interfaces for Implantable Biosensors

   Author : Janko Katic; Ana Rusu; Saul Rodriguez; Gabriel Rincón-Mora; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting interface; thermoelectric generator; glucose biofuel cell; power management; dc-dc converter; boost converter; zero-current switching; zero-voltage switching; implantable biosensor; Energiskördsgränssnitt; termoelektrisk generator; glukosbiobränslecell; energihantering; DC-DC-omvandlare; boost-omvandlare; inplanterbar biosensor; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Energy harvesting is identified as an alternative solution for powering implantable biosensors. It can potentially enable the development of self-powered implants if the harvested energy is properly handled. This development implies that batteries, which impose many limitations, are replaced by miniature harvesting devices. READ MORE

4. 2. Management of patients treated with left ventricular assist devices : A clinical and experimental study

   Author : Bengt Peterzén; Henrik Casimir-Ahn; Hans Ruthberg; Lars Wiklund; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postcardiotomy heart failure; perioperative monitoring; coronary artery bypass; heart-assist devices; heart failure; congestive; ventricular dysfunction; Thoracic surgery; Thoraxkirurgi;

   Abstract : This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. READ MORE

5. 3. Implantable devices in heart failure : studies on biventricular pacing and continuous hemodynamic monitoring

   Author : Frieder Braunschweig; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Implantable devices; congestive heart failure; biventricular pacing; hemodynamic monitoring; ambulatory; hospitalizations; positron emission tomography; stress; blood flow; loop diuretics; natriuretic peptides; hemodynamics.;

   Abstract : Chronic heart failure is a highly symptomatic syndrome associated with increasing prevalence, frequent hospital admissions and high treatment costs. Despite recent advances in drug therapy, morbidity and mortality are still high. READ MORE

6. 4. Overcoming Limitations of Iontronic Delivery Devices

   Author : Maria Seitanidou; Magnus Berggren; Daniel T Simon; Christopher Bettinger; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Organic electronic devices are considered as one of the best candidates to replace conventional inorganic electronic devices due to their electronic conductive functionality, low-cost production techniques, the ability to tune their optical and electronic properties using organic chemistry, and their mechanical flexibility. Moreover, these systems are ideal for bioelectronic applications due to their softness, biocompatibility, and most importantly, their electronic and ionic transport. READ MORE

7. 5. Organic Bioelectronic Devices for Selective Biomarker Sensing : Towards Integration with Living Systems

   Author : Chiara Diacci; Magnus Berggren; Daniel Simon; Francesca Santoro; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Inorganic materials have been the main players of the semiconductor industry for the past forty years. However, there has been a continuous interest and growth in the research and in the application of organic semiconductors (OSCs) as active materials in electronic devices, due to the possibility to process these materials at low temperature on flexible substrates, fabricate them on large-area, and upscale their fabrication using cost-effective strategies such as printing.
