Solution Overview
Problem
Conventional patch-type wireless electrocardiogram (ECG) monitoring devices have limitations such as small size, which restricts the number of electrodes that can be attached, leading to incomplete ECG measurements, signal intensity decrease, noise, and reduced reliability.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of electrodes is increased to enable 12-channel ECG measurements, then measurement precision is improved, but device size increases
Solution Approach 1:
The patch is divided into multiple detachable electrode modules that can be separately attached to different body parts. Each module contains specific electrodes (e.g., chest electrodes, limb electrodes), allowing the system to achieve complete 12-channel ECG measurements through modular assembly without requiring a single large patch
2Area of stationary object
If electrodes are moved to upper arm parts to reduce patch size, then device size is reduced, but signal intensity decreases and noise increases
Solution Approach 1:
Different electrode modules are strategically positioned at optimal locations on the body (chest, limbs) to ensure high signal quality. The chest electrode module captures cardiac action potentials directly, while limb electrode modules are positioned at standard ECG locations, ensuring each region provides the necessary signal intensity for accurate measurements
3Measurement precision
If wired connections are used to connect electrodes, then measurement precision is maintained, but device complexity and user inconvenience increase
Solution Approach 1:
The electrode modules are integrated with the patch structure, combining the electrode function and connection function into a single unified system. The modules are detachably coupled to the patch through integrated connection mechanisms, eliminating the need for separate wired connections while maintaining electrical connectivity and signal accuracy

Implementation Method 1
action potential generated when the myocardium contracts or relaxes may generate a current which spreads from a heart to a whole body. The current may generate a potential difference according to a body position. In addition, the potential difference may be detected through a surface electrode attached to skin of a human body.
