Abstract
Description
Technical Field
[0001] This invention relates to a device for sampling and detecting volatile organic compounds (VOCs), and more particularly to a stand-alone ventilated cage for sampling and monitoring that integrates wireless charging and a sensor array. Background Technology
[0002] As scientific research continues to advance, monitoring the physiological and behavioral responses of small animals (such as mice and rats) during experiments is becoming increasingly important. Particularly in drug development, disease model research, and environmental toxicology, real-time monitoring of the gaseous composition of the small animals' living environment is crucial for assessing their health status and experimental outcomes.
[0003] Existing gas monitoring equipment typically uses wired power supplies, which limits the flexibility of the equipment and the range of movement for small animals. Furthermore, these devices are often bulky and difficult to integrate into small animal cages, potentially causing unnecessary stress to the animals. At the same time, due to the limited space in small animal cages, the size and power consumption of the monitoring equipment become critical considerations.
[0004] To address these challenges, researchers have attempted to develop various portable and low-power gas monitoring devices. However, these devices still present challenges in terms of sensitivity, stability, and long-term operation. For example, some devices may require periodic calibration to maintain monitoring accuracy, which increases maintenance complexity and cost. Furthermore, existing sensor arrays may not be able to accurately distinguish and identify specific types of volatile organic compounds (VOCs), which is particularly important for accurately monitoring animal health.
[0005] While some research has explored the application of wireless charging technology in portable devices, its application in small animal cage monitoring systems remains limited.
[0006] In summary, existing small animal gas monitoring technologies and wireless charging solutions have certain limitations in practical applications. Therefore, developing an airtight container integrating wireless charging and a high-sensitivity sensor array is of great significance for improving the efficiency and accuracy of small animal experiments.
