Nanoporous silicon, commonly recognized for its photoluminescent properties, has gained attention as a new energetic
material capable of energy density more than twice that of TNT. The addition of an oxidizer solution to inert nanoporous
silicon results in an exothermic reaction when heat, friction, or focused light is supplied to the system. The energetic
material can be integrated alongside microelectronics and micro-electro-mechanical systems (MEMS) for on-chip
applications. This integration capability, along with the potential for large energetic yield, makes nanoporous energetic
silicon a viable material for developing novel MEMS Safing and Arming (S&A) technologies. While ignition of
nanoporous energetic silicon has been demonstrated for the purpose of propagation velocity measurements using a YAG
laser, in this paper we show optical ignition for potential integration of the energetic with a miniaturized S&A device.
Ignition is demonstrated using a 514nm laser at 37.7mW and a power density of 2.7kW/cm2 at a stand-off distance of
23cm. Raman spectroscopy verifies that significant stress in porous silicon is produced by a laser operating near the
power density observed to ignite porous silicon. Lastly, we integrate the nanoporous energetic silicon with a MEMS
S&A, and demonstrate transfer to a firetrain consisting of one primary and one secondary explosive using a thermal
initiator to ignite the nanoporous energetic silicon.
