A Streaming Potential/Current‐Based Microfluidic Direct Current Generator for Self‐Powered Nanosystems. (25th September 2015) - Zhang, Rui
Abstract : A simple but practical method to convert the hydroenergy of microfluids into continuous electrical output is reported. Based on the principle of streaming potential/current, a microfluidic generator (MFG) is demonstrated using patterned micropillar arrays as a quasi‐porous flow channel. The continuous electrical output makes this MFG particularly suitable as a power source in self‐powered systems. Using the proposed MFG to power a single nanowire‐based pH sensor, a self‐powered fluid sensor system is demonstrated.
