“…While these new electrode configurations generally result in higher volumetric flow rates, some inconvenience to maintenance may occur in the application. Moreover, multi-stage EHD pumps [80,81] are more efficient than simply increasing the applied voltage of a single-stage pump if the flow distance is expected to be extended [82]. Investigated connecting multiple corona wind turbines in series to extend the EHD-induced flow over longer distances and confirmed that additional stages could increase the volumetric flow produced by a single individual stage [83].…”

In recent years, functional fluidic electrohydrodynamic (EHD) pumps have attracted considerable attention due to their remarkable features, such as simple structure, quiet operation, and energy-efficient utilization. EHD liquid pumps can be used in various industrial applications, like flow transfer, thermal management, and actuator drive. In this paper, the author reviewed EHD liquid pump research in these specific aspects: the first observation of the EHD effect, its mathematical modeling, and the choice of pump structure, electrode configuration, and working medium. Based on the review, a summary of the development and latest research on EHD pumps can be provided for the readers.

In recent years, functional fluidic and gas electrohydrodynamic (EHD) pumps have received considerable attention due to their remarkable features, such as simple structure, quiet operation, and energy-efficient utilization. EHD pumps can be applied in various industrial applications, including flow transfer, thermal management, and actuator drive. In this paper, the authors reviewed the literature surrounding functional fluidic and gas EHD pumps regarding the following aspects: the initial observation of the EHD effect, mathematical modeling, and the choice of pump structure, electrode configuration, and working medium. Based on the review, we present a summary of the development and latest research on EHD pumps. This paper provides a critical analysis of the current limitations of EHD pumps and identifies potential areas for future research. Additionally, the potential application of artificial intelligence in the field of EHD pumps is discussed in the context of its cross-disciplinary nature. Many reviews on EHD pumps focus on rigid pumps, and the contribution of this review is to summarize and analyze soft EHD pumps that have received less attention, thus reducing the knowledge gap.

“…The greatest feature of an EHD pump is no moving parts such that EHD pumps can be small form factor, low profile, simple configuration, silent, vibration-free, and low power consumption. The performance of an EHD pump is governed by the factors that affect the characteristics of the electric field around the corona electrode, including the physical and electrical factors like geometry/configuration [65][66][67][68], electrode material [69,70], voltage [67,71], current [64,72], and polarity [66,73].…”

For electronics, poor thermal management could cause severe mechanical and electrical failures. Forced convective air cooling, i.e., flowing air over a hot surface, is one of the most efficient and economical solutions to manage thermal issues of electronics. Air pump is used to initiate and sustain airflow required in forced convection. This paper reviews both the mechanical and the nonmechanical air pumps that have been using widely in current electronics or have a great potential in future electronics. The mechanical pumps include axial fans, blowers, beam fans, and diaphragm pumps, while the nonmechanical pump specifically focuses on electrohydrodynamic pumps. This paper presents the working principle first and then the recent developments, including the pump itself (design, characteristics, etc.) and the applications in thermal management (placement, integration, etc.). In the end, this paper conducts the strength analysis (flow rate, pressure, noise, flexibility, and reliability) among the reviewed five types of air pumps.
