Abstract. The perpetual growth of efficient computing devices, desktop computers, and power electronic systems obliges the development of effective cooling solutions capable of efficiently dissipating high heat flux and addressing hot spots at the microscales. Electrowetting (EW) cooling is compact and responds to adaptive temperature control of electronic devices. Electrowetting on dielectric (EWOD) devices are excellent for electronic cooling in Lab-on-a-Chip technology. These devices are candid, have no moving parts, and provide precise control over movement. Micro manufacturing of cooling devices enables heat transfer efficiently as compared to conventional cooling devices. This article surveys the efforts of microfluidic-based cooling devices using the electrowetting principle with single and multiple arrayed water droplet jets on hydrophobic or superhydrophobic surfaces. It discusses the suitable surface treatment methods and materials to improve the performance of electronic devices and high computing systems.
