Abstract
A method of producing an integrated circuit-type active radioisotope battery, the method comprising exposing at least a portion of an electronically functional, unactivated integrated circuit-type battery to radiation to convert transmutable material in the unactivated battery to a radioisotope thereby producing an active cell and thus the integrated circuit-type active radioisotope battery.
Claims20
A method of producing an integrated circuit-type active radioisotope battery, the method comprising exposing at least a portion of an electronically functional, unactivated integrated circuit-type battery that is either on a substrate or comprises the substrate, wherein the unactivated integrated circuit-type battery comprises an unactivated cell that comprises:
- a conversion device for converting energy from decay products of a radioisotope into electrical energy capable of performing work;
- and
- a non-radioactive, transmutable material associated with the conversion device, wherein the transmutable material is located in one or more of the following:
- a layer in contact with the conversion device;
- the substrate;
- and the conversion device;
- to radiation to transmute at least a portion of the transmutable material to a radioisotope thereby producing an active cell, wherein the energy from the decay products of the radioisotope material are converted by the conversion device into electrical energy capable of performing work, thereby producing the integrated circuit-type active radioisotope battery.
