Summary of the Inventive Concept
An advanced wearable device system that enhances the accuracy and efficiency of physiological measurements by adaptively adjusting electrode configurations, frequency, and placement based on user activity, skin type, and environmental factors.
Background and Problem Solved
The original patent for a watch having electrodes for physiological measurements has limitations in terms of electrode placement, measurement frequency, and power consumption. The new inventive concept addresses these limitations by introducing adaptive and dynamic adjustments to the electrode configuration, frequency, and placement, thereby improving the accuracy, efficiency, and user comfort of physiological measurements.
Detailed Description of the Inventive Concept
The new inventive concept comprises a wearable device having electrodes for physiological measurements, wherein the electrodes are configured to adaptively adjust their measurement frequency based on the user's activity level. The system also includes a method for enhancing the accuracy of physiological measurements by dynamically adjusting the electrode placement on the user's body based on real-time data from a motion sensor. Additionally, the galvanic skin resistance sensing circuitry is optimized to reduce power consumption by at least 20% while maintaining a signal-to-noise ratio of at least 10. The wearable device may also include a wrist-facing surface having a pair of electrodes implemented as surface contacts, and a processing circuitry configured to apply machine learning algorithms to the electrical measurements obtained from the electrodes to detect early signs of stress or fatigue. Furthermore, the system includes a dynamically adjustable electrode spacing mechanism that adjusts the distance between the electrodes based on the user's skin type and moisture levels.
Novelty and Inventive Step
The new inventive concept introduces a novel adaptive and dynamic approach to physiological measurements, which is not obvious from the original patent. The adaptive adjustment of electrode configuration, frequency, and placement, as well as the optimization of power consumption, provides a significant improvement over the original patent.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept may include the use of different types of sensors, such as optical or acoustic sensors, to measure physiological parameters. Additionally, the system may be integrated with other wearable devices, such as smart clothing or fitness trackers, to provide a more comprehensive health monitoring system.
Potential Commercial Applications and Market
The adaptive physiological measurement system has significant commercial potential in the wearable device and healthcare industries. The system may be used in various applications, such as fitness tracking, health monitoring, and medical research, and may be marketed to consumers, healthcare professionals, and researchers.
