Electret-Nanopore Ionic Flux Generator

Towards the development of in-vivo autonomous technology, this paper proposes and investigates an electret-nanopore based ionic flux generator (IFG). The Poisson-Nernst-Planck equations were used to develop a one-dimensional analytical model under circulatory electrolytic conditions characterizing enhanced power density as electret charge saturation or pore length increased due to greater counterion flux. An approximate Electret-Nanopore IFG power density of 11.3 (W/m2) was calculated for a 500 nm pore length, 10 nm pore radius and 80% electret charge saturation system.
