Integrated Sensing Electrode for Heart Rate Monitoring in Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices with health test functions often have signal sensing components external to the device, leading to increased size and a suboptimal user experience due to the lack of integration with the display module.
Innovation Solution
A display device with a sensing electrode integrated above the substrate, allowing for electrocardio signal measurement across the surface, enabling single or multiple-point touch measurements for heart rate monitoring, and incorporating an array of switching elements for improved signal processing and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal sensing components are arranged outside the mobile device, then the health test function can be provided, but the device size increases and integration with display module is poor
Solution Approach 1:
The sensing electrode is integrated directly into the display module structure, merging the health test function with the display device. The sensing electrode is arranged above the substrate of the display module, eliminating the need for separate external sensing components and reducing overall device volume while maintaining health monitoring capabilities.
2Adaptability or versatility
If signal sensing components are arranged outside the mobile device, then the health test function can be provided, but the integration with display module is poor affecting user experience
Solution Approach 1:
The sensing electrode is integrated directly into the display module structure, merging the health test function with the display device. The sensing electrode is arranged above the substrate of the display module, eliminating the need for separate external sensing components and reducing overall device volume while maintaining health monitoring capabilities.
Solution Approach 2:
The sensing electrode serves multiple functions: it acts as both a display component substrate and a health monitoring sensor. The same structural element (substrate) supports both the display function and the health test function through the integrated sensing electrode, achieving multi-functionality within a single component system.
3Ease of operation
If sensing electrode covers the entire substrate surface, then single point measurement is enabled for convenient operation, but manufacturing complexity increases
Solution Approach 1:
The sensing electrode is divided into multiple sensing electrode units arranged in an array on the substrate. Each unit can independently sense electrocardio signals, allowing the system to provide comprehensive surface coverage while simplifying the manufacturing process through modular fabrication of individual units rather than creating a single complex continuous electrode.
