Materials and device designs are presented for electronic systems that undergo functional transformation by a controlled time sequence in the dissolution of active materials and/or encapsulation layers. Demonstration examples include various biocompatible, multifunctional systems with autonomous behavior defined by materials selection and layout.
A color schematic illustration of a wireless antenna at different points in time is shown as it undergoes a programmed sequence of functional transformation (i.e., changes in resonant frequency) due to the controlled dissolution of selected critical segments. This system represents a simple example where physical transience in certain areas of a piece of integrated electronics leads to engineered...
