Arthropods are vital to ecosystems and are among the most diverse and abundant living creatures on Earth. Understanding their physiological processes, such as cardiac activity, is essential for studying their health, behavior, and responses to environmental changes. Traditional methods of monitoring cardiac signals often rely on invasive or contact techniques that require immobilization, which limits applicability of the methods in long-term studies and disrupts the insect's natural behavior. This study proposes a noninvasive, video system to extract cardiac signals from insects by analyzing subtle body movements. The results closely align with reference data obtained from established methods, validating the system's accuracy and feasibility. The study provides a foundation for developing cost-effective, noninvasive tools that preserve insects' natural behavior welfare while offering new opportunities for ecological and physiological research.
节肢动物对生态系统至关重要，是地球上最多样化且数量丰富的生物之一。了解它们的生理过程，如心脏活动，对于研究它们的健康、行为以及对环境变化的反应至关重要。传统的心脏信号监测方法通常依赖于侵入性或接触性技术，这些技术需要使昆虫固定不动，这限制了这些方法在长期研究中的适用性，并干扰了昆虫的自然行为。本研究提出了一种非侵入性的视频系统，通过分析昆虫细微的身体运动来提取心脏信号。结果与通过既定方法获得的参考数据密切吻合，验证了该系统的准确性和可行性。该研究为开发经济高效的非侵入性工具奠定了基础，这些工具既能保护昆虫的自然行为和福利，又能为生态和生理研究提供新机会。
