QinetiQ Files Patent for Microchip Detonator

QinetiQlogoTNNIQinetiq has filed a patent with the U.S. government for a detonator chip that uses microcavities inside microelectromechanical chips to store explosive material, Electronics Weekly reports.

Paul Marks writes the system would have chemical precursors enter the chip and deposit explosives inside the chip’s microcavities.

The chip detonates by passing a current through a heater wire located inside the cavities.

Inventors aimed to reduce the risk of explosion resulting from friction, electrical spark and shock, the report said.

Different types of of weapons will require a different amount of initiator explosives for each, according to Marks.
