  1. 1. Flexible and Cellulose-based Organic Electronics

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jesper Edberg; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; conductive polymers; nanocellulose; nanofibrillated cellulose; composite materials; paper electronics; flexible electronics;

    Abstract : Organic electronics is the study of organic materials with electronic functionality and the applications of such materials. In the 1970s, the discovery that polymers can be made electrically conductive led to an explosion within this field which has continued to grow year by year. READ MORE

  2. 2. Solution-Processable Conductive Graphene-Based Materials for Flexible Electronics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jie Zhao; Uppsala universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Graphene oxide; Silver; Copper; Composite; Conductive inks; Flexible electronics; Printed electronics; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. READ MORE

  3. 3. Towards flexible audio coding

    University dissertation from Stockholm : Signaler, sensorer och system

    Author : Renat Vafin; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Audio coding; multistage coding; waveform coding; parametric coding; sinusoidal coding; Elektronik; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Abstract : thesis is about audio coding and improving flexibility thereof. Audio coding is used to reduce the bit rate needed to represent audio signals in digital format. When the available bit rate is low, parametric coding methods that use models to describe perceptually-important features of audio signals have shown their efficiency. READ MORE

  4. 4. Towards flexible organic electronics : photoelectron spectroscopy of surfaces and interfaces

    University dissertation from Linköping : Linköpings universitet
