IntelliSense silk fibroin ionotronic batteries for wildfire detection and alarm

Abstract

Wildfires often cause severe air pollution, substantial economic losses, human mortality, and environmental damage. However, their early alarming functionality still needs much improvement. Here, we report a self-powered IntelliSense wildfire detection and alarm system (SPIS-WDAS). For this purpose, the all-solid, self-healable, sustainable, fire retardant, and safe-to-use hydro-ionotronic batteries were designed to provide the long-lasting power supply for Internet of Things (IoT) chipsets in the SPIS-WDAS. In addition, environmentally interactive advantages of the ionotronic batteries, including accurate ambient temperature-and-humidity responsiveness and high sensitivity to fire emergence, allowed them to be further embedded in the environmental sensor in daily use and to serve as the alarming module for fire emergency. By further optimizing IoT-based energy management and clouded-based wireless communication technologies, the SPIS-WDAS could finally realize timely alerting for early wildfires and daily temperature monitoring in unattended fields. Relying on these advantages, the SPIS-WDAS is shown to be promising in vegetation protection applications, opening up new prospects for the design of advanced wildfire detection and alarm installations.
