1. An actively triggered transient electronic device comprising:
- a substrate;
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;
a silk overcoat provided on at least a portion of said one or more inorganic components; and
an actuator responsive to a user initiated external trigger signal and operably connected to said one or more inorganic components, wherein upon said device receiving said external trigger signal said actuator at least partially removes said silk overcoat so as to expose at least a portion of said one or more inorganic components to said external or internal stimulus, thereby providing a programmable transformation of the actively triggered transient electronic device in response to said external trigger signal, wherein said programmable transformation provides a change in function of the actively triggered transient electronic device from a first condition to a second condition.

23. A method of using an actively triggered transient electronic device, said method comprising the steps of:
-
providing the actively triggered transient electronic device comprising; a substrate; 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;a silk overcoat provided on at least a portion of said one or more inorganic components; and an actuator responsive to a user initiated external trigger signal and operably connected to said one or more inorganic components, wherein upon said device receiving said external trigger signal said actuator at least partially removes said silk overcoat so as to expose at least a portion of said one or more inorganic components to said external or internal stimulus, thereby providing a programmable transformation of the actively triggered transient electronic device in response to said external trigger signal, wherein said programmable transformation provides a change of the function of the actively triggered transient electronic device from a first condition to a second condition corresponding to a second functionality different from a first functionality; and providing said user initiated external trigger signal to said electronic device, wherein said actuator directly or indirectly initiates at least partial transformation of said one or more inorganic components, thereby providing said programmable transformation. - View Dependent Claims (24, 25)
