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 five different applications by combining triboelectric fingerprint signals and deep learning. Furthermore, an image sensor is integrated to extract the visual features of liquids, and the recognition capability of the liquid-sensing system is improved to up to 96.0%. The design of this dual-sensory fusion self-powered liquid-sensing system, along with the droplet-tasting sensor that can autonomously generate triboelectric signals, provides a promising technological approach for the development of effective and low-cost liquid sensing for liquid food safety identification and management.

Introduction:

Liquid identification plays a pivotal role in a wide range of industries, spanning from quality control in food and beverages to environmental monitoring of liquids. The conventional methods for liquid identification often rely on complex and expensive instruments. The emergence of the self-powered triboelectric taste-sensing system with dual-sensory fusion brings a transformative approach to this field, combining principles of triboelectricity and sensory fusion to achieve accurate and cost-effective liquid identification.

The self-powered triboelectric taste-sensing system operates on the basis of the triboelectric effect, where friction between two materials generates an electric potential difference. This system ingeniously utilizes the concept of taste-sensing, where different liquids exhibit distinct triboelectric behaviors. By integrating multiple sensing units with varying sensitivities, the dual-sensory fusion aspect of the system enhances accuracy by cross-referencing and corroborating signals from different sensors.
