Paper Abstract
Transient electronic devices are a new technology development whose main characteristic is that its components can
disappear in a programmed and controlled way, which means such devices have a pre-engineered service life.
Nowadays, transient electronics have a large application field, involving from the reduction of e-waste in the planet until
the development of medical instruments and implants that can be discarded when the patients do not need it anymore,
avoiding the trouble of having an extra procedure for them. These devices must be made from biocompatible materials
avoiding long-term adverse effects in the environment and patients.
It is fundamental to develop an analytical model that allows describing the behavior of these materials considering cases
which its porosity may be constant or not, in presence of water or any other biofluid. In order to accomplish this analysis
was solve the reactive diffusion equation based on Bromwich’s integral and the Residue theorem for two material cases,
those whose porosity is constant, and those whose porosity increases linearly in terms of its thickness, where was found
a general expression. This allows to the analysis of the relation of the electric resistance (per unit length) and the rate of
dissolution of the material.
