Abstract

This work discusses the fabrication and experimental testing of multiplexed electrospray (ESpray) devices micromachined in silicon substrates. Variations to the experimental test stands from previous work demonstrating Ethanol spraying are described for the successful demonstration of JP-8 spraying. Five different ESpray devices were microfabricated to gain an understanding of the operating limits for stable electrospraying. The microfabrication of ESpray devices consists of independently fabricating its two components (extractor and nozzle array layers) with standard photolithography and deep reactive ion etching (DRIE) of silicon substrates. Precise alignment (<2
