We describe the concept of a 3D self-folding package (SFP) for sensors and electronic devices. The strategy is based on a self-assembly strategy wherein 2D panels interconnected with hinges spontaneously fold-up when they are released from the substrate; self-folding can be triggered by temperature or selected chemicals. The strategy enables packaging of devices in porous polyhedral geometries that can either be untethered or substrate-bound. Self-folding can enable packaging of devices in small 3D form factors and may enable efficient cooling due to porosity. The utilization of this self-folding platform to enable 3D packaging of cantilever sensors and magnetic field sensitive strain gauges is summarized.
