Researchers in Japan based the electrochemical dual transducer (ECDT) design on the electrohydrodynamic (EHD) pump they had previously designed. The pump consisted of a symmetrical arrangement of planar electrodes, which allowed easy control of the flow direction by simply changing the voltage. The arrangement enabled an obstruction-free even flow in each direction due to the same strength of the electric field on either side. They evaluated sensing performance in terms of range of detectable flow, rate, sensitivity, response, and relaxation times, and used mathematical modeling to understand the sensing mechanism. The ECDT does not require any special equipment or complex processing for its fabrication. It is small, lightweight, demonstrates a wide range of sensitivity, does not require special equipment or complex processing for its fabrication, and can be easily integrated into a fluidic system without bloating or complexity…read more.
