Abstract

A flexible electronic structure includes a flexible substrate comprising an electrically conductive top substrate layer and an opposing electrically conductive bottom substrate layer and a component. The component can include a component substrate non-native to the flexible substrate having a component substrate top side and an opposing component substrate bottom side, a planar component top electrode disposed on the component substrate top side and electrically connected to the electrically conductive top substrate layer thereby defining a planar electrical contact, and a planar component bottom electrode disposed on the component substrate bottom side and electrically connected to the electrically conductive bottom substrate layer thereby defining a planar electrical contact. The component can be disposed between the electrically conductive top substrate layer and the electrically conductive bottom substrate layer.
