▎ 摘　　要

NOVELTY - Ultra-coupling bionic strain sensor comprises a micro-nano coupling bionic crack array set on the flexible substrate. The micro-nano coupling bionic crack array is composed of N first arc (1) and N second arc (2). The first arc and the second arc in the same circle array, where N is an integer greater than 0, resistance layer is deposited on the flexible substrate and the micro-nano coupling bionic crack array, and electrode is set on the resistance layer. USE - Ultra-coupling bionic strain sensor for use in a flexible electronic device. Uses include but are not limited to a wear-resistant device, an electronic skin, and a robot. ADVANTAGE - The ultra-coupling bionic strain sensor has ultra-high sensitivity, good durability, quick time and recovery time, simple structure, good performance and good performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the ultra-coupling bionic strain sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of ultra-coupling bionic strain sensor. 1First arc lines 2Second arc lines
