Abstract

The invention relates to a substrate used for a flexible electronic device, a flexible electronic component and a manufacturing method of a flexible electronic component. The substrate is made of stretchable flexible material and is used for holding conductors. The substrate has a surface and a plurality of bosses arranged on the surface. The plurality of bosses are arranged in a first direction,and a recessed portion is arranged between every two adjacent bosses in the first direction. When the substrate is holding the conductors, the conductors are attached to the bosses and parts of the conductors, extending in the recessed portion between every two adjacent bosses, will not touch the bottom surface of the recessed portion. According to the invention, the tensile performance of the whole flexible electronic device can be improved while the safety of the interconnection lines is guaranteed.

Description

technical field [0001] The present invention relates to a substrate capable of improving the stretchability of flexible electronic devices, a flexible electronic component with improved stretchability, and a method for manufacturing the flexible electronic component. Background technique [0002] Since the birth of stretchable flexible electronic devices, higher flexibility and stretchability (also known as ductility) have been the constant pursuit of device structure designers. Current stretchable and flexible electronic devices are mainly realized through the integration of functional hard thin film devices and flexible substrates (hereinafter referred to as substrates). The hard film devices are connected by metal interconnection lines. The substrate is for example made of a flexible polymer such as polydimethylsiloxane (PDMS). [0003] Both metal interconnects and flexible substrates contribute to the stretchability of flexible electronics. The stretchability is usual...
