Abstract [en]

Vertical organic electrochemical transistors (OECTs) have been manufactured solely using screenprinting. The OECTs are based on PEDOT:PSS (poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid)), which defines the active material for both the transistor channel and the gateelectrode. The resulting vertical OECT devices and circuits exhibit low-voltage operation, relativelyfast switching, small footprint and high manufacturing yield; the last three parameters are explainedby the reliance of the transistor configuration on a robust structure in which the electrolyte verticallybridges the bottom channel and the top gate electrode. Two different architectures of the verticalOECT have been manufactured, characterized and evaluated in parallel throughout this report. Inaddition to the experimental work, SPICE models enabling simulations of standalone OECTs andOECT-based circuits have been developed. Our findings may pave the way for fully integrated, lowvoltageoperating and printed signal processing systems integrated with e.g. printed batteries, solarcells, sensors and communication interfaces. Such technology can then serve a low-cost basetechnology for the internet of things, smart packaging and home diagnostics applications.

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.

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.

Abstract [en]

Printed electronics are considered for wireless electronic tags sensors within the future Internet-of-things (IoT) concept. As a consequence of the low charge carrier mobility of present printable organic inorganic semiconductors, the operational frequency of printed rectifiers is not high enough to enable direct communication powering between mobile phones printed e-tags. Here, we report an all-printed diode operating up to 1.6 GHz. The device, based on two stacked layers of Si NbSi2 particles, is manufactured on a flexible substrate at low temperature in ambient atmosphere. The high charge carrier mobility of the Si microparticles allows device operation to occur in the charge injection-limited regime. The asymmetry of the oxide layers in the resulting device stack leads to rectification of tunneling current. Printed diodes were combined with antennas electrochromic displays to form an all-printed e-tag. The harvested signal from a Global System for Mobile Communications mobile phone was used to update the display. Our findings demonstrate a new communication pathway for printed electronics within IoT applications._x000D_
