Abstract
An initiator system includes a firing pin and a piezoelectric-based energy harvester that generates and stores electric energy when impacted by the firing pin. The electric energy is independently available at a first output and second output of the energy harvester. An electronic time delay is coupled to the second output for generation of an electric trigger signal using the electric energy available at the second output. The electric trigger signal is generated at a selected period of time after the electric energy is available at the second output. An initiation-energy generator is coupled to the first output for the storage of electric energy available thereof. The initiation-energy generator is also coupled to the electronic time delay to receive the electric trigger signal, and uses stored electric energy to generate an initiation explosion when the electric trigger signal is received.
