| Research Abstract |
Aim of the research project was the design and combination of light-addressable electrodes (LAE) in conjunction with the light-addressable potentiometric sensor (LAPS), to create a flexible miniaturized sensor and actuator system. Both technologies use the common technique to address there active region with the help of a light-spot. To create a combined system, digital light processing (DLP) technology was utilized to enable the generation of precise light spots for both technologies. Finally, measurements were carried out which combined the local change of the pH value induced by a LAE structure and the observation and detection of those local pH changes by a LAPS structure, both combined in a single micro-chamber measurement cell. This research resulted in valuable results and a deeper understanding in the mechanisms of both technologies.
