Abstract
A destroy on-demand electrical device includes a substrate layer formed using a soluble material (e.g., a Germanium oxide), a semi-conductor layer formed from a material that can become soluble upon further processing (e.g., Germanium) and conductive elements, formed from a metallic material such as Copper. The device is coupled with one or more disintegration sources that contain disintegration agents (e.g., Hydrogen Peroxide) that can promote disintegration of the device. The device can be destroyed in response to actuation of the disintegration sources, for example by actuation of a source that produces Hydrogen Peroxide for use in oxidizing the semi-conductor layer. Water can be used to dissolve dissolvable substrate layers. The semi-conductor layer can be destroyed by first processing this layer to form a dissolvable material and dissolving the processed layer with water. The remaining Copper components disintegrate once their underlying layer have been dissolved and/or by use of a salt.
