MEMS Munitions Power Source

A cost effective power source for smart munitions becomes an increasingly difficult problem for small diameter rounds as traditional reserve battery and inertial generator approaches have construction techniques that don’t scale down well. Munitions have unique needs compared to most power systems requiring unusually long shelf life, unusually short working life, and require high reliability under harsh conditions. In addition, due to the high volume expected for small diameter rounds, the ability to deliver a solution that is low cost is important. Microfabrication approaches to create a power source can allow less volume to be consumed in the packaging and ancillary structures and more in the energy producing device itself, and at the same time allow high volume manufacturing for reduced cost. Nuvotronics proposes to develop a miniature battery that meets required volume and energy density goals while meeting the environmental requirements. We will utilize our patented PolystrataTM metal micromachining process and our in-depth experience in Si micromachining to create a device that is low-cost and producible in high volumes.
