Abstract
Flexible devices including conductive traces with enhanced stretchability, and methods of making and using the same are provided. The circuit die is disposed on a flexible substrate. Electrically conductive traces are formed in channels on the flexible substrate to electrically contact with contact pads of the circuit die. A first polymer liquid flows in the channels to cover a free surface of the traces. The circuit die can also be surrounded by a curing product of a second polymer liquid.
