Abstract [en]

Low-cost passive wireless electronic sensor labels glued onto packages are highly desirable since they enable monitoring of the status of the packages for instance along the logistic chain or while stored at a shelf. Such additional sensing feature would be of great value for many producers and vendors, active in e.g. the food or construction industries. Here, we explore a novel concept for wireless sensing and readout, in which the humidity sensitive ionic motion in a polyelectrolyte membrane is directly translated into a shift of the resonance frequency of a resonance circuit. Thanks to its simplicity, the wireless sensor device itself can be manufactured entirely using common printing techniques and can be integrated into a low-cost passive electronic sensor label.

Abstract [en]

Polymers are very attractive materials that can be tailored for specific needs and functionality. They can for instance be made electrically insulating or (semi)conducting, with specific mechanical properties. Polymers are often processable from a solution, which enables the use of low-cost manufacturing techniques to fabricate polymer devices. Polymer-based electronic and electrochemical devices and sensors have been developed.

This thesis is related to the polarization characteristics in polyelectrolyte thin film capacitor structures. The polarization characteristics have been analyzed at various humidity levels for polyelectrolyte capacitors alone and when incorporated as the gate-insulating material in polyelectrolyte-gated organic field-effect transistors. Both limitations and possibilities of this class of transistors have been identified. Also, a concept for wireless readout of a passively operated humidity sensor circuit is demonstrated. The sensing mechanism of this sensor is related to the polarization in a polyelectrolyte thin film capacitor. This sensor circuit can be manufactured entirely with common printing technologies of today and can be integrated into a low-cost passive sensor label.

Abstract [en]

Polymers are very attractive materials that can be tailored for specific needs and functionalities. Based on their chemical structure, they can for instance be made electrically insulating or semiconducting with specific mechanical properties. Polymers are often processable from a solution, which enables the use of conventional low-cost and high-volume manufacturing techniques to print electronic devices onto flexible substrates. A multitude of polymer-based electronic and electrochemical devices and sensors have been developed, of which some already has reached the consumer market.

This thesis focuses on polarization characteristics in polyelectrolyte-based capacitor structures and their role in sensors, transistors and supercapacitors. The fate of the ions in these capacitor structures, within the polyelectrolyte and at the interfaces between the polyelectrolyte and various electronic conductors (a metal, a semiconducting polymer or a network of carbon nanotubes), is of outermost importance for the device function. The humidity-dependent polarization characteristics in a polyelectrolyte capacitor are used as the sensing probe for wireless readout of a passively operated humidity sensor circuit. This sensor circuit can be integrated into a printable low-cost passive sensor label. By varying the humidity level, limitations and possibilities are identified for polyelectrolyte-gated organic field-effect transistors. Further, the effect of the ionic conductivity is investigated for polyelectrolyte-based supercapacitors. Finally, by using an ordinary electrolyte instead of a polyelectrolyte and a high-surface area (supercapacitor) gate electrode, the device mechanisms proposed for electrolyte-gated organic transistors are unified.

3. Controlling ion transport in organic devices

Abstract [en]

Organic electronics and printed electronics have been attracting more and more research interest in the past decades. Polymers constitute an important class of materials within the field organic electronics due to their unique physical and chemical properties. One great benefit of the polymers is their solution processability, which provides us the possibility to utilize conventional printing techniques to fabricate devices on flexible substrates.

This thesis focuses on utilizing and controlling the ion transport in polyelectrolytes in electronic devices for different applications. A polyelectrolyte is a polymer in which the polymeric backbone includes ionic sites compensated by counter ions.

Firstly, we have used a specific property of the polyelectrolyte: its electric polarization is strongly dependent on the humidity level. The ions are screened by water molecules; this improves the mobility and dissociation of ions. A polyelectrolyte-based capacitor is thus ideal to sense humidity. Such a capacitor is integrated into an LC resonant circuit possessing a specific resonant frequency. The wirelessly detected resonant frequencies of the sensing circuit indicate the corresponding humidity levels. With the appropriate choice of materials, the complete sensing circuit (resistor, capacitor, capacitor-like sensor head) can be screen-printed on an antenna manufactured using a roll-to-roll dry phase patterning technique.

Secondly, we have modified the polarization characteristics of ions in a polyelectrolyte layer by trapping the ions in molecular macrocycles dispersed in a polymer overlayer. The resulting remanent polarization is read out as a hysteresis loop in the capacitance-voltage characteristic of a capacitor. The strategy is further implemented in an electrolyte-gated organic transistor to control its threshold voltage by applying defined programming voltages. Although the lifetime of the “remanent” polarization is rather short, the concept might be further improved to fit those of memory applications.

Finally, we take use of the ionic selectivity of a polyelectrolyte to stabilize the operation of a water-gated organic field-effect transistor. The polyanionic membrane is added onto the semiconductor channel to prevent small anions of the aqueous electrolyte to penetrate into the p-channel semiconductor. Moreover, the polyelectrolyte layer protects the semiconductor and thus strongly stabilizes the shelf lifetime of those transistors. This improved version of the water-gated organic transistor is a candidate for developing transistor-based sensors working in, for instance, biological media.
