Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.

电化学要求每个电极通过导线连接到外部电路。对于许多电极，这意味着许多电线。导线限制了阵列中的电极密度，并规定电极结构必须预先确定。该项目旨在通过使用光将每个电极顺序连接到单个导线来消除每个电极对导线的需求。这将通过使用改性的硅电极来实现，其中用光照射会导致照明点处的电导率增加。该项目将探索影响空间分辨率的变量，并将这些想法应用于纳米电子学的软连接和电分析的高密度电极阵列。
