This paper introduces a new platform for droplet-based microfluidic manipulation on flexible substrates. Electrowetting forces are applied to drops via copper electrodes embedded in a flexible polyimide film. The electrodes are protected with coatings of poly(dimethylsiloxane) (PDMS) and teflon. Performance properties and applications of these devices are explored. Droplets with sufficiently small volume (<7.3<math>\mu L</math>)
