Stimuli‐Responsive Liquid Metal Hybrids for Human‐Interactive Electronics

Abstract The development of stimuli‐responsive liquid metal hybrids (SrLMHs) is of great interest, owing to their ability to induce responsivity and innovative properties to liquid metal (LM) when hybridized. Various stimuli‐responsivities yield new realms for SrLMHs in the fields of human‐interactive electronics (HIEs). This review provides an overview on the development of SrLMHs for HIEs. First, discussion is on SrLMH systems regarding their configuration, the materials utilized for the establishment of new hybrid materials, various stimuli‐responsive systems, their operation mechanisms, and applications. Followed by the characterization and summary of SrLMHs, details on how SrLMHs are incorporated for HIEs, and their progression is reviewed, from a single mechanical stimulus sensing capability to multi‐modal functionality. Finally, the review concludes on the overall progress of SrLMH‐based HIEs, their advancement direction, and the challenges that still remain.
