Dawei Zhang, Haider Butt, Lianxi Zheng
Abstract
This study presents a comprehensive bibliometric analysis of global research trends in the field of ionic sensors for electronic skin (e-Skin) from 2001 to March-2025, based on data retrieved from the Web of Science Core Collection.Using VOSviewer for network visualization, the analysis explores publication growth, leading countries and institutions, key authors, funding agencies, and thematic research clusters.Results indicate a sharp increase in research output since 2017, largely driven by advances in flexible electronics, materials science, and the rising demand for wearable and bioinspired technologies.China emerges as the most prolific contributor, with strong institutional and funding support, while South Korea and the USA also play key roles.Keyword and co-citation analyses reveal a strong research focus on hydrogel-based materials, stretchability, transparency, and multifunctional sensor integration.This bibliometric overview provides valuable insights into the evolution, research focus, and collaborative landscape of ionic e-skin research, offering guidance for future studies and interdisciplinary innovation. Table of ContentsInnovative Description: This review paper provides an overview of current trends, key contributors, and research hotspots in the domain of ionic sensors for e-skin.
