Beetle‐Inspired Gradient Slant Structures for Capacitive Pressure Sensor with a Broad Linear Response Range
Southwest Jiaotong University · Korea Advanced Institute of Science and Technology
Abstract
Abstract Flexible pressure sensors with broad linearity range and excellent sensor‐to‐sensor uniformity have attracted unprecedented attention in the electronic skins, human–machine interfaces, and environmental monitoring. However, challenges including poor sensor‐to‐sensor uniformity owing to the randomness of the used nanomaterials or porous structures and saturated response that leads to a restricted linearity range because of structural stiffening have been yet addressed. Herein, a novel dielectric layer based on beetle‐inspired gradient slant structures (GSS) is proposed to endow capacitive pressure sensors with extensive linearity range and excellent sensor‐to‐sensor uniformity. The excellent…
