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.

研究项目的目的是与可调的可调电极（LAE）的设计和组合，并结合使用光原样的电位传感器（LAPS），以创建一个灵活的微型传感器和执行器系统。两种技术都使用通用技术在灯光亮点的帮助下解决活动区域。为了创建一个组合的系统，使用数字灯处理（DLP）技术来使两种技术的精确光点产生。最后，进行了测量结果，该测量结合了LAE结构引起的pH值的局部变化，以及通过单圈结构的观察和检测这些局部pH值的变化，均在单个微轴轴测量单元中合并。这项研究为两种技术的机制带来了宝贵的结果和更深入的了解。
