    Integration of a droplet-based microfluidic system and silicon nanoribbon FET sensor2016In: Micromachines, ISSN 2072-666X, E-ISSN 2072-666X, Vol. 7, no 8, article id 134Article in journal (Refereed)
    Abstract [en]

    We present a novel microfluidic system that integrates droplet microfluidics with a silicon nanoribbon field-effect transistor (SiNR FET), and utilize this integrated system to sense differences in pH. The device allows for selective droplet transfer to a continuous water phase, actuated by dielectrophoresis, and subsequent detection of the pH level in the retrieved droplets by SiNR FETs on an electrical sensor chip. The integrated microfluidic system demonstrates a label-free detection method for droplet microfluidics, presenting an alternative to optical fluorescence detection. In this work, we were able to differentiate between droplet trains of one pH-unit difference. The pH-based detection method in our integrated system has the potential to be utilized in the detection of biochemical reactions that induce a pH-shift in the droplets.

    Preparation of iron oxide nanocrystals by surfactant-free or oleic acid-assisted thermal decomposition of a Fe(III) alkoxide2008In: Journal of Magnetism and Magnetic Materials, ISSN 0304-8853, E-ISSN 1873-4766, Vol. 320, p. 781-787Article in journal (Refereed)
    Abstract [en]

    A new non-hydrolytic, alkoxide-based route was developed to synthesize iron oxide nanocrystals. Surfactant-free thermal decomposition of the iron 2-methoxy-ethoxide precursors results in the formation of uniform iron oxide nanocrystals with an average size of 5.6 nm. Transmission electron microscope study shows that the nanocrystals are protected against aggregation by a repulsive surface layer, probably originating from the alkoxy-alkoxide ligands. Addition of oleic acid resulted in monodisperse nanocrystals with an average size of 4 nm. Mössbauer analysis confirmed that the nanocrystals mainly consisted of maghemite. Analysis of the magnetic hysteresis loop measurements and the zero field and field cooled measurements displayed an excellent fit to established theories for single-domain superparamagnetic nanocrystals and the size of the magnetic domains correlated well to the crystallite size obtained from transmission electron microscope.

    Effective particle magnetic moment of multi-core particles2015In: Journal of Magnetism and Magnetic Materials, ISSN 0304-8853, E-ISSN 1873-4766, Vol. 380, p. 221-226Article in journal (Refereed)
    Abstract [en]

    In this study we investigate the magnetic behavior of magnetic multi-core particles and the differences in the magnetic properties of multi-core and single-core nanoparticles and correlate the results with the nanostructure of the different particles as determined from transmission electron microscopy(TEM). We also investigate how the effective particle magnetic moment is coupled to the individual moments of the single-domain nanocrystals by using different measurement techniques: DC magnetometry, AC susceptometry, dynamic light scattering and TEM. We have studied two magnetic multi-core particle systems – BNF Starch from Micromod with a median particle diameter of 100 nm and FeraSpin R from nanoPET with a median particle diameter of 70 nm – and one single-core particle system – SHP25 from Ocean NanoTech with a median particle core diameter of 25 nm.

    Printed passive matrix addressed electrochromic displays2013In: Organic electronics, ISSN 1566-1199, E-ISSN 1878-5530, Vol. 14, no 12, p. 3371-3378Article in journal (Refereed)
    Abstract [en]

    Flexible displays are attracting considerable attention as a visual interface for applications such as in electronic papers paper electronics. Passive or active matrix addressing of individual pixels require display elements that include proper signal addressability, which is typically provided by non-linear device characteristics or by incorporating transistors into each pixel. Including such additional devices into each pixel element make manufacturing of flexible displays using adequate printing techniques very hard complicated. Here, we report all-printed passive matrix addressed electrochromic displays (PMAD), built up from a very robust three-layer architecture, which can be manufactured using standard printing tools. Poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate) (PEDOT:PSS) serves as the conducting electrochromic pixel electrodes carbon paste is used as the pixel counter electrodes. These electrodes sandwich self-assembled layers of a polyelectrolyte that are confined to desired pixel areas via surface energy patterning. The particular choice of materials results in a desired current vs. voltage threshold that enables addressability in electronic cross-point matrices. The resulting PMAD operates at less than 3 V, exhibits high colour switch contrast without cross-talk promises for high-volume low-cost production of flexible displays using reel-to-reel printing tools on paper or plastic foils._x000D_

    Fast-switching all-printed organic electrochemical transistors2013In: Organic electronics, ISSN 1566-1199, E-ISSN 1878-5530, Vol. 14, no 5, p. 1276-80Article in journal (Refereed)
    Abstract [en]

    Symmetric fast (ˆ¼5 ms) on-to-off off-to-on drain current switching characteristics have been obtained in screen printed organic electrochemical transistors (OECTs) including PEDOT:PSS (poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid)) as the active transistor channel material. Improvement of the drain current switching characteristics is made possible by including a carbon conductor layer on top of PEDOT:PSS at the drain electrode that is in direct contact with both the channel the electrolyte of the OECT. This carbon conductor layer suppresses the effects from a reduction front that is generated in these PEDOT:PSS-based OECTs. In the off-state of these devices this reduction front slowly migrate laterally into the PEDOT:PSS drain electrode, which make off-to-on switching slow. The OECT including carbon electrodes was manufactured using only standard printing process steps may pave the way for fully integrated organic electronic systems that operate at low voltages for applications such as logic circuits, sensors active matrix addressed displays._x000D_

    Mikrosystem – möjligheternas teknik: Om klassificering, metoder och tillämpning2000Book (Other academic)
    Abstract [sv]

    Mikrosystem är ett mycket expansivt område som erbjuder stora möjligheter till effektivisering och miniatyrisering av komplexa produkter. Nya unika egenskaper i samverkan med låga tillverkningskostnader har medfört att mikrosystemtekniken, MST, Microsystems Technology, erövrar såväl existerande produktområden som helt nya, t ex: bilar, flygplan medicinsk teknik, mindetektorer, rymdindustri m fl.

    Denna bok presenterar mikrosystemen och deras möjligheter. Den inleds med en unik marknadsöversikt där olika tillämpningsområdens utveckling och framtid diskuteras. En detaljrik framställning och klassificering av etablerade och kommande mikrosystem bildar en bred kunskapsbank för såväl specialister som oinvigda inom området. För konstruktörer som t ex vill öka sin kunskap om olika kategorier av sensorer förklaras begrepp och funktionsprinciper på ett utförligt sätt. Boken är även en lämplig introduktion till sensorer och mikromekanik på landets alla olika ingenjörsutbildningar.

    A novel 3-axis monolithic silicon accelerometer1995In: Digest of Techn. Papers, The 8th Int. Conf. on Solid-State Sensors and Actuators, Transducers ‘95/ Eurosensors IX), Volume II, pp. 558-561., 1995Conference paper (Refereed)
    Abstract [en]

    Working prototypes of a novel 3 axis monolithic silicon accelerometer have been manufactured at Chalmers University of Technology in co operation with Saab Combitech AB and the Department of Solid State Electronics. Experience from the prototypes is most encouraging as they have confirmed the theoretical predictions of negligible cross-axis sensitivity. The accuracy in the separation of an arbitrary directed acceleration into acceleration vectors in a Cartesian system of coordinates has shown to be high almost beyond expectation. The accelerometer has good potential to develop into a low cost 3 axis accelerometer in the 0 2 g range with a resolution of about 10 mg. This in part due to the simple manufacturing process.

    Abstract [en]

    We investigate the potential of different pre-fetching and/or caching strategies for different user behaviour with respect to surfing or browsing in a catch-up-TV network. To this end we identify accounts and channels associated with strong or weak surfing or browsing respectively and study the distributions of hold times for the different types of behaviour. Finally we present results from a request prediction model and a caching simulation for the different types of behaviour and find that the results are relatively similar.

    Printable All-Organic Electrochromic Active-Matrix Displays2007In: Advanced Functional Materials, ISSN 1616-301X, E-ISSN 1616-3028, Vol. 17, no 16, p. 3074-Article in journal (Refereed)
    Abstract [en]

    All-organic active matrix addressed displays based on electrochemical smart pixels made on flexible substrates are reported. Each individual smart pixel device combines an electrochemical transistor with an electrochromic display cell, thus resulting in a low-voltage operating robust display technology. Poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(styrenesulfonate) (PSS) served as the active material in the electrochemical smart pixels, as well as the conducting lines, of the monolithically integrated active-matrix display. Different active-matrix display addressing schemes have been investigated a matrix display fill factor of 65€‰% was reached. This is achieved by combining a three-terminal electrochemical transistor with an electrochromic display cell architecture, in which an additional layer of PEDOT:PSS was placed on top of the display cell counter electrode. In addition, we have evaluated different kinds of electrochromic polymer materials aiming at reaching a high color switch contrast. This work has been carried out in the light of achieving a robust display technology that is easily manufactured using a standard label printing press, which forced us to use the fewest different materials as well as avoiding exotic complex device architectures. Together, this yields a manufacturing process of only five discrete patterning steps, which in turn promise for that the active matrix addressed displays can be manufactured on paper or plastic substrates in a roll-to-roll production procedure._x000D_

    Merits of Buried Grid Technology for SiC JBS Diodes2012In: GALLIUM NITRIDE AND SILICON CARBIDE POWER TECHNOLOGIES 2, 2012, p. 415-424Conference paper (Refereed)
    Abstract [en]

    The SiC Schottky barrier diodes for 200 degrees C to 250 degrees C operation have been developed using buried grid (BG) technology. 2A and 10A, 1700V BG JBS diodes have been fabricated and evaluated. Manufactured 10A, 1700V BG JBS diodes have leakage current at least three orders of magnitude lower compared to the typical data sheet values of the commercial devices. The leakage current at 250 degrees C is of the same order of magnitude as that of the commercial devices at 175 degrees C. The two alternative technologies for realization of BG, implantation and epitaxy, have been compared by simulations. The epitaxial grid is shown to have superior potential for best trade-off between on-state voltage and leakage current.

    Objective Video Quality Assessment - Towards large scale video database enhanced model development2015In: IEICE transactions on communications, ISSN 0916-8516, E-ISSN 1745-1345, Vol. E98.B, no 1, p. 2-11Article in journal (Refereed)
    Abstract [en]

    The current development of video quality assessment algorithms suffers from the lack of available video sequences for training, verification and validation to determine and enhance the algorithm’s application scope. The Joint Effort Group of the Video Quality Experts Group (VQEG-JEG) is currently driving efforts towards the creation of large scale, reproducible, and easy to use databases. These databases will contain bitstreams of recent video encoders (H.264, H.265), packet loss impairment patterns and impaired bitstreams, pre-parsed bitstream information into files in XML syntax, and well-known objective video quality measurement outputs. The database is continuously updated and enlarged using reproducible processing chains. Currently, more than 70,000 sequences are available for statistical analysis of video quality measurement algorithms. New research questions are posed as the database is designed to verify and validate models on a very large scale, testing and validating various scopes of applications, while subjective assessment has to be limited to a comparably small subset of the database. Special focus is given on the principles guiding the database development, and some results are given to illustrate the practical usefulness of such a database with respect to the detailed new research questions.

    Printed electrochemical instruments for biosensors2015In: ECS Transactions, 2015, Vol. 66, no 37, p. 1-13Conference paper (Refereed)
    Abstract [en]

    Mobile diagnostics for healthcare, food safety and environmental monitoring, demand a new generation of inexpensive sensing systems suitable for production in high volume. Herein we report on the development of a new disposable electrochemical instrument exploiting the latest advances in printed electronics and printed biosensors. The current system is manufactured under ambient conditions with all interconnections printed; electrochemical measurements and data elaboration are realized by the integration onto the platform of two chips: a MICROCHIP-PIC24F16KA101 and a Texas Instrument's LMP91000. A PEDOT.PSS vertical electrochromic display (VECD) is also incorporated into the system to visualize the data. A printed Enfucell 3V manganese dioxide battery was used to deliver the required power. Finally, in order to demonstrate the utility of the system, screen-printed sensors for the detection of glucose were added and the performance of the overall system was evaluated.

    Browsing the Real World using Organic Electronics, Si-Chips, and a Human Touch2016In: Advanced Materials, ISSN 0935-9648, E-ISSN 1521-4095, Vol. 28, no 10, p. 1911-1916Article in journal (Refereed)
    Abstract [en]

    Two different e-labels were developed to explore the feasibility and to identify scientifi c and engineering challenges of the Real-World-Web platform. First was a printed biosensor e-label, comprising Si-chips with an array of different printegrated devices, and second, an e-label to explore the feasibility of transferring data, through the human body, between a mobile device and different distributed e-labels, adhered onto the body or onto dedicated devices and surfaces of one's ambience. The silicon chips utilized in e-labels, include analogue and digital circuitry to receive and handle sensory input, to perform signal processing, and to transmit information to antennas and displays. When used, the e-label is turned on, and a sample is then added onto the sensor area. The display provides simple instructions and updated information to the user. All data handling, electrical probing, and analysis of the sensor is performed by the Si-chips, and the sensing data is finally shown in the printed display. The second e-label exemplifies an ID-tag for body area networks (BAN) communication applications, which, in part, is manufactured and integrated in the same way as the first e-label, but with another choice of Si-chips and capacitive antennas.

    SAFEWATER - Innovative tools for the detection and mitigation of CBRN related contamination events of drinking water2015In: Procedia Engineering, ISSN 1877-7058, E-ISSN 1877-7058, Vol. 119, p. 352-359Article in journal (Refereed)
    Abstract [en]

    The safety and or security of drinking water can be threatened by natural disasters, accidents or malevolent attacks. The European FP7 project SAFEWATER aims at developing a comprehensive event detection and event management solution for drinking water security management and mitigation against major deliberate, accidental or natural CBRN related contaminations. New cost-effective C, B, and RN sensors will be developed. An innovative concept with a broad network of low-cost sensors - "domestic sensors" (complementary to a set of sensors in strategic locations) will be developed. A technology platform will be provide which is able to capture and analyze the data collected by the sensors and from other information systems and give a full overview of the crisis to the responders by means of online look-ahead simulations to efficiently manage potential crises. For testing the SAFEWATER solution it will be integrated with on utility-partners' information systems.
