Abstract

Silicon-based resorbable electronics is a class of high-performance technology that has the ability to physically disappear completely, at prescribed rates in a benign way. When exposed to biofluids or water, enabled devices from medical implants to environmental sensors can fully resorb in the human body ("bioresorbable") or dissolve in the environment ("ecoresorbable") to avoid long-term adverse effects or the need for recollection. Analytical models for dissolution kinetics of constituent materials and devices with layered structures represent important design tools for resorbable electronic systems. In this chapter, we review models of reactive diffusion and analytical solutions in single- and double-layered structures. The time of complete physical disappearance and rate of dissolution depend on the reaction constants, the diffusivities, and the thickness of each layer, along with other properties of the materials and solutions.
