Abstract
A self-destructing device includes a frangible substrate having at least one pre-weakened area. A heater is thermally coupled to the frangible substrate proximate to or at the pre-weakened area. When activated, the heater generates heat sufficient to initiate self-destruction of the frangible substrate by fractures that propagate from the pre-weakened area and cause the frangible substrate to break into many pieces.
