Waterseepage-induced geological hazards (SIGHs), including landslides,collapse, debris flow, and ground fissures, often cause substantialhuman mortality, economic losses, and environmental damage. However,an early warning of geological water seepage remains a significantchallenge. A self-powered, cost-effective, reliable, and susceptibleSIGH early warning system (SIGH-EWS) is reported herein. This systemdesigned the all-solid, sustainable, fire retardant, and safe-to-usebio-ionotronic batteries to provide a stable power supply for Internetof Things chipsets. Furthermore, the batteries' outstandinghumidity and water sensitivity allow sensing of the water seepageemergence. Integrating energy management and wireless communicationsystems, the SIGH-EWS realizes timely alerts for early water seepagein different water and soil environments with a time resolution inseconds. Based on these merits, the SIGH-EWS demonstrates promisingapplication prospects for early warning of geological disasters andcorresponding design strategies that can potentially guide the designsof next-generation geological hazard alarm systems.
