EHDIP is a novel MEMS manufacturing process that makes use of the Instability of polymer materials when exposed to electric fields. By using non uniform E-fields it is possible to shape the polymer into defined meso and micro-scale structures which are subsequently cured to give finished MEMS devices. The quick process time, comparitive lack of process steps, as well as the ability to produce hitherto unrealised topographies - such as continous surfaces, makes EHDIP an attractive field of research. The work is focused on the characterisation of the process, with particular attention towards defining the factors that promote growth in the polymers, as well as experimentation with different toplogies in order to find applications in the micro-fluidic, optics and microwave fields.
