Synergistic Integration of Triboelectric Mechanisms and Dual-Sensory Fusion in a Self-Powered System for Economically Efficient Discrimination of Liquids
Abstract: In the realm of liquid identification technology, a groundbreaking innovation has emerged in the form of a self-powered triboelectric taste-sensing system with dual-sensory fusion capabilities. This research presents a comprehensive study of this novel system, detailing its design, functionality, and potential applications. By harnessing the principles of triboelectricity and dual-sensory fusion, this system offers an effective, low-cost solution for liquid identification, opening new avenues in fields such as food safety, beverage quality control, and environmental monitoring. Infusing human taste perception into smart sensing devices to mimic the processing ability of gustatory organs to perceive liquid substances remains challenging. Here we developed a self-powered droplet-tasting sensor system based on the dynamic morphological changes of droplets and liquid–solid contact electrification. The sensor system has achieved accuracies of liquid recognition higher than 90% in
