Aiming at flexible and transparent electronics, we present an integration process for ZnO based thin-film transistors on a freestanding polymeric substrate using spray-coating for the deposition of the semiconducting film. Moreover, a cost efficient post-treatment applying intensive UV irradiation combined with high humidity atmosphere leads to a simple integration process for ZnO TFTs with low parameter variations.

Verfahren oder Vorrichtung zur kapazitiven Abbildung unter Verwendung einer Anordnung aus Zeilenelektroden 101 und Spaltenelektroden 102 auf einem Substrat, wobei die Kreuzkapazit?t zwischen Zeilen- und Spaltenelektroden anhand der Eigenkapazit?t der Zeilenelektrode 101 erhalten wird, die gemessen wird, w?hrend die übrigen Elektroden geerdet sind, anhand der Eigenkapazit?t der Spaltenelektroden 102, die gemessen wird, w?hrend die übrigen Elektroden geerdet sind, und anhand einer kombinierten Eigenkapazit?t der Zeilen- und Spaltenelektroden, die gemessen wird, w?hrend die übrigen Elektroden geerdet sind. Ein bevorzugtes Ausführungsbeispiel ist ein Hand-Wandscanner zum Ermitteln von versteckten Merkmalen, der ein zweidimensionales Display in der Gr??e der Anordnung aufweist, welches darüber angeordnet ist. Versteckte Merkmale, welche die Zeile-zu-Spalte-Kreuzkapazit?ten beeinflussen, werden somit in ihrer echten Gr??e und an ihrer echten Position abgebildet.

The efficiency of dye sensitized solar cells (DSSCs) is strongly influenced by the quality of the front electrode. To remove dispersal additives and to enable sintering effects the TiO2 layer has to be heated up to 450°C for one hour. Nevertheless, for flexible DSSCs the process temperature is limited by the foil to about 150°C. Hence, a sintering of the particles is not possible and the cleaning effect is also declined, but both can be compensated with the development presented in this paper. This paper demonstrates that after 90 min of permanent intensive UV-irradiation nearly all additives are evaporated. Furthermore, to decrease the stress on the foil a pulsed UV-irradiation is performed and the pulse-pause-ratio optimized.

Harumanis or its scientific name as Mangifera indica is a popular mango in Malaysia due to its unique aroma and taste, despite its expensive price. The high demand for this mango and its potential in export has been the reason why this tropical fruit being a national agenda for the Malaysian government to classify it as the specialty fruit from Perlis (smallest state in Malaysia). As the sole university in Perlis, University of Malaysia Perlis (UniMAP) has taken the initiative to develop greenhouse specifically for Harumanis mango. To support this, a real-time greenhouse monitoring system has been proposed. The system was developed based on Wireless sensor Networks technology which consists of three parts: sensing module, radio communication module and gateway module. This system is able to provide real time monitoring of the important factors in plant growth such as the carbon dioxide, temperature, humidity level in the greenhouse. The performance result shows that the temperature inside the greenhouse is slightly higher compared to the open field; which meets the crop requirements. At night, the greenhouse microclimate drops and equilibrates to the surrounding temperature and humidity. This condition ensures good flowering and fruiting of sweet and juicy mangoes.
