Dual-Electrode Wearable for Heart Rate and Blood Oxygen Detection

The device segments the detection function into separate electrodes: a first electrode on the front surface and a second electrode on the back surface. This segmentation allows each electrode to be optimized for specific detection purposes while keeping the overall device structure relatively simple. The segmentation principle resolves the contradiction by dividing the complex detection task into manageable components without requiring a completely complex device architecture.

The smart watch device achieves multi-functionality by integrating both traditional reminder functions and new body data detection functions into a single device. The electrodes are designed to detect multiple types of body data including heart rate, blood oxygen content, and other physiological parameters, making the device universal for both simple reminders and comprehensive health monitoring, thereby resolving the contradiction between functionality and complexity.

The device implements self-service by automatically detecting and monitoring body data without requiring active user intervention. The electrodes continuously monitor physiological parameters such as heart rate and blood oxygen content, and the device automatically processes and displays this information. This self-service approach maintains ease of operation while significantly improving adaptability, as users don't need to manually operate complex detection mechanisms.

The device merges the body data detection function with the existing smart watch interface and operation system. The detection results are integrated into the display and notification systems already familiar to users, combining new detection capabilities with existing operational patterns. This merging approach preserves ease of operation by using familiar interfaces while adding enhanced functionality through body data monitoring.
