We demonstrate the use of super absorbent sodium polyacrylate polymers (SAPs) as actuator materials to trigger destruction of microchips upon exposure to aqueous environments. To implement the actuator the backside of a microchip is partially diced with an array of grooves. The grooves are pack filled with 25 µm SAP particles and sealed within a PDMS package containing a flow distribution network...
A single layer nanothermite spin coated gel has been utilized as a solid-state exothermic energy release layer for triggered microchip transience. A proportional combination of self-assembled CuO/Al nanothermite and Napalm-B as gelling agent has been used to develop for the first time a spinable nanothermite film onto the surface of a micro-chip. This layer when ignited instantaneously releases enough...
