A Review of Electrowetting on Dielectric Applications of Carbon Nanotubes

The unique properties carbon nanotubes (CNTs) have shown potential for use in electrowetting on dielectric (EWOD) technology. The conductivity, thermal and optical properties of CNTs can be exploited to cater to various needs in the many layers of a EWOD device. CNTs have been used as conductive layers, thermal management elements, transparent conductive layers, chemical and biological sensors. This mini review explores the various attempts of exploiting the excellent electrical and physical properties CNTs in EWOD and similar applications. The review thus identifies the overlap in these two fields that indicates a strong future opportunity to use CNTs in EWOD systems.
