Abstract
The invention provides transient devices, including active and passive devices that electrically and/or physically transform upon application of at least one internal and/or external stimulus. Materials, modeling tools, manufacturing approaches, device designs and system level examples of transient electronics are provided.
Claims28
A passive transient electronic device comprising:
- a substrate;
- and
- one or more inorganic components supported by said substrate;
- wherein said one or more inorganic components independently comprise a selectively transformable material, wherein said one or more inorganic components have a preselected transience profile in response to an external or internal stimulus;
- wherein at least partial transformation of said one or more inorganic components provides a programmable transformation of the passive transient electronic device in response to said external or internal stimulus and at a pre-selected time or at a pre-selected rate, wherein said programmable transformation provides a change in function of the passive transient electronic device from a first condition to a second condition.

A method of using a passive transient electronic device, said method comprising the steps of:
- providing the passive transient electronic device comprising:
- a substrate;
- and
- one or more inorganic components supported by said substrate;
- wherein said one or more inorganic components independently comprise a selectively transformable material, wherein said one or more inorganic components have a preselected transience profile in response to an external or internal stimulus;
- wherein at least partial transformation of said one or more inorganic components provides a programmable transformation of the passive transient electronic device in response to said external or internal stimulus and at a pre-selected time or at a pre-selected rate, wherein said programmable transformation provides a change in function of the passive transient electronic device from a first condition to a second condition.
- exposing said passive transient electronic device to said external or internal stimulus, thereby programmably transforming said passive transient electronic device.
