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.
Claims19
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;
- wherein change in function transforms said one or more inorganic components from:
- (i) a NOR gate to a NAND gate;
- (ii) an inverter to an isolated transistor;
- (iii) a resistor to a diode;
- (iv)a NAND gate to an inverter;
- (v) a NOR gate to an isolated transistor;
- or
- (vi) a NAND gate to an isolated transistor.

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, thereby providing said change in function of said passive transient electronic device from:
- (i) a NOR gate to a NAND gate;
- (ii) an inverter to an isolated transistor;
- (iii) a resistor to a diode;
- (iv) a NAND gate to an inverter;
- (v) a NOR gate to an isolated transistor;
- or
- (vi) a NAND gate to an isolated transistor.
