Wearable Electrode Segmentation for Continuous Biometric Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices face limitations in maintaining continuous health information collection and accuracy due to the need for detachment during charging, which disrupts biometric data acquisition and reduces the reliability of long-term health monitoring.
Innovation Solution
An electronic device with at least two front electrodes that allows for continuous health information acquisition and charging without detachment, using a wired or wireless charging cradle, and a processor that adjusts data acquisition methods based on charging status to ensure uninterrupted biometric data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the electronic device is detached from the user's body for charging, then charging can be performed, but health information cannot be measured during charging
Solution Approach 1:
The patent divides the electrode system into multiple independent electrodes (first electrode and second electrode) positioned at different locations on the device. This segmentation allows different electrodes to serve different functions simultaneously - some electrodes can be used for charging while others maintain contact with the user's body for health monitoring, resolving the contradiction between charging and continuous health information collection.
2Loss of information
If the electronic device is worn on the user's body for health monitoring, then biometric information can be collected, but charging cannot be performed without detachment
Solution Approach 1:
The patent makes the electrodes universal by enabling them to serve multiple functions. The same electrodes that are used for health monitoring can also be used for charging, or different electrodes can be allocated for different functions. This multi-functionality allows the device to maintain health monitoring capability while simultaneously performing charging operations without requiring detachment.
3Duration of action of moving object
If the measurement period is extended to maximize usage time, then battery lifespan is improved, but accuracy of health information deteriorates
Solution Approach 1:
The patent ensures continuous health information collection by maintaining electrode contact with the user's body throughout the entire usage period, including during charging. The segmented electrode system allows one electrode to be used for charging while another continues health monitoring, eliminating gaps in measurement and ensuring both long usage time and continuous accurate data collection.

AI summary
An electronic device that can be worn on a user's body and an operating method thereof is disclosed. An electrode for charging and measuring is included in a front side of the electronic device. The electronic device includes a battery, a charging circuit for charging the battery, a bio-sensor, and a processor. The processor is configured to determine whether the battery is being charged through the charging circuit. If the battery is not being charged, the processor is configured to acquire biometric information by using a first method through the bio-sensor, and if the battery is being charged, the processor is configured to acquire the biometric information by using a second method through the bio-sensor.
