Short paper: Design of a dielectrophoresis-based portable device for monitoring pollution in water deposits

Abstract

Pollution in water deposits is a great health issue. Portable devices installed in water deposits to form a real time, pollution monitoring system would be of great help. Research has demonstrated the use of dielectrophoresis (DEP) where particle manipulation is required. A portable, programmable device for manipulating pollutant particles has been developed, so data or images of samples can be analyzed, transmitted and stored. The system has a signal generator for electrical stimulation, a microfluidic device, a particle detection sub-system, and a data transmitter. It can be programmed to manipulate a specific type of particles and transmit resulting data or image. A portable prototype is achieved, which can be installed in any water deposit and programmed to perform regular fluid samples and analysis, to maintain a web-based, real time data center.
