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. 11,857,313.

Summary of the Inventive Concept

The inventive concept presents a suite of direct improvements and enhancements to sweat biosensing companion devices and subsystems, addressing limitations of existing technologies in terms of accuracy, efficiency, and user experience.

Background and Problem Solved

The original patent disclosed sweat biosensing companion devices and subsystems with limitations in providing simultaneous measurements, ensuring chronological assurance, and offering personalized health recommendations. The new inventive concept tackles these limitations by integrating sweat and non-sweat biosensors, leveraging machine learning algorithms, and providing real-time monitoring and data analytics capabilities.

Detailed Description of the Inventive Concept

The enhanced sweat biosensing companion devices and subsystems comprise a sweat collection module, a sweat biosensor, a non-sweat biosensor, a data analytics module, and a mobile application. The sweat biosensor detects analytes in sweat, while the non-sweat biosensor detects analytes in a non-sweat biofluid. The data analytics module analyzes the sweat samples and provides personalized health recommendations. The mobile application receives and displays the detected analyte data in real-time, enabling users to track their health status. The machine learning algorithm corrects for errors in sweat analyte measurements based on historical data and environmental factors, ensuring high accuracy.

Novelty and Inventive Step

The new claims introduce the integration of sweat and non-sweat biosensors, the use of machine learning algorithms for chronological assurance and error correction, and the provision of real-time monitoring and personalized health recommendations. These advancements constitute a significant improvement over the original patent, offering a more comprehensive and user-friendly sweat biosensing solution.

Alternative Embodiments and Variations

Alternative embodiments may include wearable devices with integrated sweat and non-sweat biosensors, handheld devices with interchangeable biosensors, or desktop devices with advanced data analytics capabilities. Variations may include the use of different machine learning algorithms, the integration of additional sensors or biomarkers, or the development of specialized devices for specific applications such as athletics or neonatology.

Potential Commercial Applications and Market
