Abstract Due to the significant economic losses and safety issues caused by gas pipeline leaks, timely detection of minor leaks in pipelines is crucial important. Herein, we present an intelligent liquid metal bubble generator (LMBG) chamber capable of converting mechanical leakage signals into real-time electrical feedback through the electrochemical conversion mechanism at the liquid metal interface.
