👉 A panel fluid, often utilized in the context of electrohydrodynamic (EHD) and microfluidic systems, is a specialized liquid medium designed to facilitate the manipulation of fluids at microscopic scales. These fluids are engineered with unique properties such as high surface tension, low viscosity, and specific electrical conductivity to enable precise control over fluid movement through electric fields. Panel fluids are crucial in applications like lab-on-a-chip devices, where they help in the precise mixing, separation, and transport of small fluid volumes, thereby enhancing the efficiency and accuracy of various microfluidic processes. Their design allows for the creation of stable droplets, controlled flow patterns, and efficient heat transfer, making them indispensable in advanced microfluidic and nanofluidic technologies.
