论文介绍-----光驱动的微气泡发动机

我们乘坐的汽车由发动机驱动,发动机与人类生活密切相关,像心脏驱使血液循环一样,微发动机作为动力源头大有用武之地。微发动机在光驱人工智能机器人、将药物输送到人体病变部位、强化流体混合与反应、光流体器件(泵、阀等)、调控太阳能系统的气泡动力学等领域有广泛应用前景。万物生长靠太阳,光能具有非接触、无污染等优点,对周围环境没有电磁干扰,然而,光驱发动机研制并非易事。但光照射表面时,“光颗粒”动量变化产生的力称为光压,光压太小,使其应用受到很大限制。有科学家进行了光压驱动液-液界面的实验,表明光压只能驱动表面张力小于10-7N/m的表面变形,该表面张力比水小9个量级。
