This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,297.

Summary of the Inventive Concept

A wearable physiological sensor system that ensures constant pressure against a subject's skin through an adaptive pressure control mechanism, enhancing measurement accuracy and reliability.

Background and Problem Solved

The original patent described a wearable band with a physiological sensor attached to an inward-facing surface. However, the system lacked a mechanism to maintain a constant pressure between the sensor and the subject, leading to inaccurate measurements. The new inventive concept addresses this limitation by introducing an adaptive pressure control mechanism that adjusts pressure in response to changes in the subject's physiological state.

Detailed Description of the Inventive Concept

The enhanced physiological sensor system consists of a wearable band with an inward-facing surface and an outward-facing surface, a sensor module attached to the inward-facing surface, and an adaptive pressure control mechanism. The adaptive pressure control mechanism uses real-time physiological data from the sensor module to adjust pressure, ensuring a constant pressure between the sensor module and the subject. This mechanism can be integrated with machine learning algorithms to predict and adjust pressure based on historical physiological data. The system can also include a pressure compensation mechanism that uses feedback from the sensor module to adjust pressure in real-time.

Novelty and Inventive Step

The new inventive concept introduces an adaptive pressure control mechanism that dynamically adjusts pressure in response to changes in the subject's physiological state, providing a more accurate and reliable measurement system. This is a significant improvement over the original patent, which lacked a mechanism to maintain a constant pressure.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of sensors, such as optical or electrical sensors, or incorporating additional features, such as temperature or humidity sensing. The adaptive pressure control mechanism could also be implemented using different algorithms or control systems.

Potential Commercial Applications and Market

The enhanced physiological sensor system has significant commercial potential in the healthcare industry, particularly in applications such as chronic disease management, athletic performance monitoring, and medical research. The system's ability to provide accurate and reliable measurements could lead to improved patient outcomes, enhanced athletic performance, and new insights in medical research.
