Abstract: A digital biomedical device includes a substrate forming a cavity, a seal formed around the cavity, a lid coupled to the substrate by the seal, a reactive metal structure comprising a plurality of metal layers, wherein the reactive metal structure is a component of at least one of the substrate and the lid, a metal trace configured to initiate a self-propagating reaction between the plurality of metal layers of the reactive metal structure and release contents of the cavity, and a power supply configured to apply an electric current to the metal trace.
