About

Ji Hwan Moon is a leading researcher in the field of soft robotics and smart materials, with a primary focus on developing high-performance fiber-based actuators and sensors. His work centers on the hybridization of carbon nanomaterials—such as graphene oxide (GO) and carbon nanotubes (CNTs)—with polymers to create fibers that mimic the remarkable properties of natural spider silk and skeletal muscle. Moon’s major contributions include the fabrication of thermally responsive torsional and tensile fiber actuators using GO and nylon-6,6, which offer a low-cost alternative to traditional nanocarbon actuators. He also pioneered a CNT–elastomer actuator that achieves a tensile contraction of 30.5% at just 5 V, with a maximum work capacity 110 times that of mammalian muscle—a breakthrough for practical artificial muscle applications. His work has garnered over 140 citations, with his most-cited paper receiving 48 citations. More recently, Moon has advanced self-powered multidirectional strain sensors for electronic skin and electrochemical torsional artificial muscles that could replace electric motors in miniaturized systems. His 2024 development of a wearable multi-ply potentiometric sensor for an electronic tongue further demonstrates his versatility, pushing the boundaries of wearable taste-sensing technology for robotics and food safety monitoring.
