Advanced grenade concept with novel placement of MEMS fuzing technology

An explosive system, comprising:

• electronic components being disposed on a circuit board;
• a micro-electromechanical systems fuze comprising a plurality of safety mechanisms, wherein the micro-electromechanical systems fuze is communicatively coupled to the electronic components;
• and
• a piezoelectric energy source being situated substantially adjacent to a main explosive charge for detecting and harvesting energy based on a launch acceleration, wherein the piezoelectric energy source is communicatively coupled to the electronic components and the micro-electromechanical systems fuze,
• wherein each of the circuit board, the micro-electromechanical systems fuze, and the piezoelectric energy source are disposed in a rear portion of the explosive system, and
• wherein the micro-electromechanical systems fuze comprises a spin armed slider, a solely electronic command lock, and a setback lock to hold the spin armed slider in place.

A method, comprising:

• providing a round, and a micro-electromechanical systems fuze;
• providing a piezoelectric energy source being acted upon by substantially adjacent components for powering the micro-electromechanical systems fuze;
• wherein the piezoelectric energy source detects and harvests energy based on a launch acceleration
• launching a round, wherein the round comprises the micro-electromechanical systems fuze in a rear portion of the round after explosive charges;
• releasing a setback lock on the micro-electromechanical systems fuze upon launching;
• initiating a timer upon launching;
• releasing a command lock on the micro-electromechanical systems fuze based on the timer thereby allowing a micro-detonator on the micro-electromechanical systems fuze to slide into position;
• and
• detecting impact and detonating the round through the micro-detonator
• wherein the micro-electromechanical systems fuze comprises a spin armed slider, a solely electronic command lock, and the setback lock to hold the spin armed slider in place.
