Water-driven energy harvesting characteristics of MoSi thin film devices

Abstract

In this article, we experimentally examine, for the first time, the water-driven energy harvesting characteristics of molybdenum silicide (MoSi) thin film devices. The water-driven energy harvesting characteristics of MoSi devices originate from the direct contact between water and the surface of the device. The magnitude of the generated voltage varies from about 0.1 to 7 mV depending on the conditions of the devices being in contact with water. Voltage continues to be generated between the wet and dry sides of the MoSi device as long as water persists on its surfaces, even though it does not stream or flow on the surface of the device. The influence of the size of the electrodes and their area of contact with water on the water-driven energy harvesting characteristics of MoSi devices is also investigated.
