Background and Problem Solved
The original patent disclosed a wearable device with a varying impedance antenna, which, while effective, has limitations in terms of signal quality and power consumption. The new inventive concept addresses these limitations by introducing a dynamic impedance tuning system that adjusts the antenna's impedance in real-time, based on the user's physiological data.
Detailed Description of the Inventive Concept
The wearable device comprises a radio frequency antenna with a dynamic impedance tuning system that adjusts the impedance of the antenna in real-time, based on the user's physiological data. This optimization enables improved signal quality and reduced power consumption. The device can transmit radio frequency signals through the varying impedance antenna and analyze the reflected signals to determine the user's hydration level, glucose concentration, and other physiological metrics. Additionally, the device can incorporate a machine learning algorithm that correlates the user's physiological data with environmental factors to provide personalized health recommendations.
Novelty and Inventive Step
The new claims introduce a paradigm shift by incorporating real-time impedance tuning, self-healing antennas, and personalized health management, making the original inventive concept obsolete. The dynamic impedance tuning system, in particular, is a novel and non-obvious feature that significantly improves the antenna's performance and enables accurate physiological data monitoring.
Alternative Embodiments and Variations
Alternative embodiments may include wearable devices with varying impedance antennas that adapt to different environmental conditions, such as temperature or humidity. Another variation could be a device that incorporates multiple antennas with different impedance profiles to enhance signal quality and reduce interference.
Potential Commercial Applications and Market
The inventive concept has significant commercial potential in the healthcare and wearable technology industries, enabling accurate physiological data monitoring and personalized health management. The device can be marketed as a premium wearable device for health-conscious consumers, athletes, and individuals with chronic health conditions.
