Abstract

ABSTRACT Constructing multiscale structures has been regarded as a promising strategy to improve the overall performance of flexible pressure sensors. However, their manufacturing approach remains a challenge due to the lack of mild, compatible, and scalable processing methods. In this work, a high‐precision and controllable fabrication strategy based on a novel secondary replica molding approach is proposed. A paraffin intermediate mold is introduced to reduce potential damage to functional sensing materials, which enables the precise construction of arbitrary structures. The resulting multiscale‐structured octet‐truss piezoresistive pressure sensor (MSPS‐O) exhibits exceptional batch‐to‐batch reproducibility with a deviation of volume‐normalized initial resistance
