Abstract
We present a digital-microfluidic (DMF) platform able to manipulate varied droplets of essential oils to program personal and regional fragrance. On this platform, three essential oils were tested, including orange, palmrose and clove, that represent top, middle and base notes of fragrance, respectively. The essential oil droplets (volume 40 nL) were generated and then mixed at arbitrary ratios by the liquid dielectrophoresis (LDEP) force. The fragrance was released along with the time by resistive heating. By employing DMF, minute volume of the essential oil droplets are driven, offering a programmable fragrance with a finer time resolution. In this prototype, we attempt to encode fragrance with the three basic notes, as image is composed of three primary colors and sound is made up with the seven basic notes. Herein, we used this platform to independently generate 40 nL essential oil droplets in the 40
