Stretchable substrate, electronic apparatus having the stretchable substrate, and method of manufacturing the electronic apparatus

An electronic apparatus, comprising:

• a substrate comprising first parts and second parts;
• electronic devices disposed on each of the first parts of the substrate;
• and
• electrical connections disposed on each of the second parts of the substrate, the electrical connections having wrinkles with random distribution.

A method of manufacturing an electronic apparatus, the method comprising:

• forming a mold pattern on a base substrate, the mold pattern defining openings configured to partially expose the base substrate, and having wrinkles with random distribution;
• forming a resin for transcription on the base substrate, the resin for transcription being configured to fill up the openings and cover the mold patterns;
• and
• curing the resin for transcription to form a substrate comprising first parts corresponding to the openings and second parts corresponding to the top portion of the mold pattern having the wrinkles with random distribution.
