“…In order to solve this problem, many small power sources have been explored, such as biofuel cells [1][2][3][4][5][6][7][8][9][10], energy harvesting devices [11,12], ultra-capacitors [13,14], micro-batteries [15][16][17][18][19][20][21][22][23][24], etc. Typical millimeter sized biofuel cells and miniature energy harvesting devices produce peak powers of a few micro-watts or less, which is usually not sufficient for most applications.…”

“…Many different micrototal analysis systems (lTAS's), e.g., for detection of ions and biological cells [1,2], rely on the electromechanical principles such as electrokinetic transport [3,4] and electrochemical reaction [5,6]. The liquid junction potential (LJP) may be another electrochemical phenomenon of crucial importance that can be utilized to produce electricity in a concentration fuel cell [7] or for passive control of charged particles [8].…”

“…The LJP occurs due to different ionic diffusivities at an interface between neighboring streams in an inhomogeneous fluid system. While most previous works [6,7,9] on the LJP were based on electroneutrality in macroscopic systems, its validity is known to be compromised for a smaller system dimension in the range of a micro-and nanoscales [10,11]. The electroneutrality assumption replaces the Poisson equation for electric potential, which poses some difficulty in conjunction with the nonlinear transport equation in a numerical solution procedure.…”

Most people were not aware of the role of energy as a basic force that drives the development and economic growth of the world until the two great oil crises occurred. According to the conservation law, energy not only exists in various forms but is also capable of being converted from one form to another. The common forms of energy are mechanical energy, chemical energy, internal energy, electrical energy, atomic energy, and electromagnetic energy, among others. The fluids in nature serve as the most common carriers and media in the energy conversion process. Following the rapid development of microelectromechanical systems (MEMS) technology, the energy supply and conversion issue in micro/nano scale has also been introduced in research laboratories worldwide. With unremitting efforts, great quantities of micro/ nano scale energy devices have been investigated. Micro/ nanofluid shows distinct features in transporting and converting energy similar to their counterpart macroscale tasks. In this paper, a series of micro/nanofluid-enabled energy conversion devices is reviewed based on the transformation between different forms of energy. The evaluation and contradistinction of their performances are also examined. The role of micro/nanofluid as media in micro/nano energy devices is summarized. This contributes to the establishment of a comprehensive and systematic structure in the relationship between energy conversion and fluid in the micro/nano scale. Some fundamental and practical issues are outlined, and the prospects in this challenging area are explored.
