Results: Utilizing NHANES (National Health and Nutrition Examination Survey) data, we leveraged anthropometric measurements for children within the specified age groups. By transforming and adapting this data, we obtained age-appropriate anthropometric characteristics, including height, weight, sitting height, hip breadth, and leg length, among others. These data allowed us to develop more accurate representations of children's physical dimensions, enabling us to better assess their seating needs in school buses. Our analysis of the transformed NHANES data revealed significant variations in anthropometric measurements among children of different age groups. For example, elementary school-aged children exhibited shorter sitting heights and leg lengths compared to middle and high school students. These differences underscored the importance of considering age-specific anthropometric data when designing seating solutions for school buses. Moving forward, the plan would be to conduct further research involving direct data collection from children within the specified age groups. By gathering precise measurements and feedback from children themselves, we aim to refine our understanding of their seating preferences and comfort requirements. This data will enable us to validate and enhance our initial findings, ultimately informing the development of more tailored and inclusive seating designs for school buses.

Methods: The project involves analyzing existing sit-stand stool products, benchmarking design parameters, and synthesizing anthropometric data specific to the Indian population. Multivariate analysis is conducted to assess levels of disaccommodation, and optimization techniques are used to determine the ideal stool height range for accommodating Indian users.

Results: The analysis reveals disparities between existing sit-stand stool products and the anthropometric characteristics of the Indian population. Optimization efforts focused on adjusting stool height show significant improvements in accommodation levels, enhancing comfort and usability for Indian individuals across various height ranges. Customized ergonomic solutions are essential to meet the diverse needs of the Indian demographic in home and office environments.

Problem Statement: Current medical alert systems cater either to the elderly, offering limited functionalities, or to younger users with smartwatches, which may overwhelm older adults. There is a lack of wearable medical devices optimized for users aged 55-80, who seek both emergency assistance and health biometric tracking.

Solution: Introducing LifePatch, a discreet wearable sensor patch designed for users aged 55-80. LifePatch tracks biometrics such as heart rate, blood pressure, and glucose levels, offering emergency alerts and health monitoring in one device. It aims to bridge the gap between existing medical alert systems and smartwatches by providing a comprehensive solution tailored to the needs of older adults.

Target Population: LifePatch targets users aged 55-80, including the baby boomer generation, who seek a wearable device for both emergency assistance and health monitoring. This demographic values simplicity, flexibility, and affordability in their medical devices.

Method: Our approach to designing and developing LifePatch begins with a steadfast commitment to compliance with international medical device standards, including ISO 13485 and ISO 14971. By adhering to these rigorous specifications, we ensure the highest levels of quality management throughout the product lifecycle. Furthermore, our design process is deeply rooted in user-centric principles, with a particular focus on addressing the unique needs and challenges of older adults. Through extensive persona development and user feedback, we glean insights into vision impairments, diminished motor control, skin sensitivities, and technology adoption patterns among the elderly. These insights drive every aspect of our prototype development, from the selection of materials to the integration of advanced sensor technology. Our prototype, meticulously crafted using Solidworks, prioritizes comfort and flexibility, with dimensions optimized for compatibility with existing devices and direct skin application. Additionally, our power and storage systems leverage cutting-edge graphene-based technology to maximize efficiency and minimize charging times, ensuring continuous and reliable operation.

Results: LifePatch offers a discreet, flexible, and affordable solution for older adults seeking both emergency assistance and health monitoring. With its customizable sensors, wireless connectivity, and user-friendly interface, LifePatch addresses the identified gap in the market of medical alert devices for users aged 55-80. The device has the potential for future growth and expansion into other market areas, offering opportunities for improving healthcare monitoring across different age groups.
