In order for small wireless sensor devices to be completely autonomous, each device must be able to generate and store its own energy for its entire lifetime. Due to various processing limitations, standard microfabrication techniques are impractical for fabricating these energy components directly on-chip.

Instead, we present a direct-write, pneumatic dispenser printing method for additively fabricating solid-state, microbatteriess and capacitors directly on-chip in room temperature, ambient conditions. This proves to be a flexible method for integrating electrochemical energy storage components onto a device, and tailoring its performance to a specific application’s demands.
