Fabrication and electrorotation of a novel epoxy based micromotor working in a uniform DC electric field

Abstract: Abstract.We have presented the first direct observation of electric field induced rotation of epoxy based polymer rotors. Polymer disks, hollow cylinders and gears were prepared in few micrometer dimensions as rotors. Electrorotation of these sub-millimeter sized tools was studied under uniform DC electric field. The effects of shape, size and thickness were investigated. The novel epoxy based micro devices show intensive spinning in uniform DC electric field. The rotational speed of micron-sized polymer rotor… Show more

“…In our previous work, we have reported the development of micron-sized polymer composites disks that showed electrorotation in uniform DC electric field [8][9][10][11]. Here we report that a novel polymer has been used for realization of a rotor part of side drive micromotor, based on the electrorotation phenomena [1].…”

“…The polymer hardens in a pre-defined 3D shape upon illumination with focused laser light. The detailed description of the experimental procedure can be found our other paper [11]. Electrorotation was studied in oil mixture containing substantial amount of triglicerid of oleic-, palmitic-, and linoleic acids.…”

“…Во-первых, проявлением ВК при электрореологическом эффекте (отрицательном или положительном), заключающемся в снижении или, соответственно, росте вязкости суспензий при приложении электрического поля [3][4][5]. Вторая причина -это попытка использования ВК для создания электростатических микромоторов [6,7], например, для MEMS-устройств. Препятствием служат особенности ВК: (i) пороговый, по отношению к величине приложенного поля, механизм вращения и (ii) случайный характер направления оси вращения частиц (при ортогональности направлению поля).…”

“…При очевидном различии природы ЦФГЭ [8,9] и ФДЭ феноменологическое описание генерации электрического поля (E CPG ) практически одинаково. В случае пространственно однородной монополярной генерации (электронов) выражение для E CPG (при условии n d ≪ n 0 ) имеет следующий вид: (7). По имеющимся оценкам [10] E CPG ∼ 10 −2 V · cm −1 , что несопоставимо мало по сравнению с E D , однако имеются пути его увеличения.…”
