Abstract
Inkjet-printers from the company Epson and others can be used to fabricate low-cost sensors on coated PET films. By using nanoparticle-based dispersions resistive temperature dependent sensors, strain gauges, thermocouples and pressure sensors can be fabricated. For these purposes the gauge factors, Seebeck coefficients and temperature coefficients of resistance for Ag, Carbon Black and PEDOT:PSS dispersions on Mitsubishi® and Pelikan® PET substrates are characterized. Furthermore, piezoresistive effects in transverse and longitudinal strain directions are discussed. Additionally, a printed sensor system for measuring strains within a surface is presented. Finally, an injection-moulding process and a lamination process are used to improve the mechanical scratching of those sensors.
Zusammenfassung
Dieser Beitrag beschreibt die Herstellung von kostengünstigen Sensoren mit handelsüblichen Tintenstrahldruckern auf beschichteten PET-Folien. Durch die Verwendung von Nanopartikel-basierten Dispersionen können bspw. resistive temperaturabhängige Sensoren, Dehnungsmessstreifen, Thermoelemente und Drucksensoren realisiert werden. Zu diesem Zweck werden die K-Faktoren von Dehnungsmessstreifen, die Seebeck-Koeffizienten und die elektrischen Temperaturkoeffizienten für Ag-, Carbon Black- und PEDOT:PSS Dispersionen auf Mitsubishi und PET Substraten ermittelt. Außerdem werden die piezoresistiven Effekte der Dispersionen in Quer- und Längsdehnungsrichtungen behandelt. Im Weiteren wird ein gedrucktes Sensorsystem zur Messung von Dehnungen auf einer Oberfläche vorgestellt. Abschließend wird das In-Mold-Verfahren bzw. ein Laminierungsprozess verwendet, um die mechanische Kratzfestigkeit der Sensoren zu verbessern.
