November Sparks: Purdue BME Patents Driving Innovation
Innovation is at the heart of the Weldon School. Each patent represents a leap forward in solving real-world problems through engineering and science. In November, faculty secured patents that advance healthcare, security and sustainability. These breakthroughs show how Purdue BME transforms ideas into impact.
Collagen Encapsulation of Insulin-Producing Cells
Inventor: Sherry Harbin
Diabetes affects millions worldwide and researchers continue to search for better treatments. This patent introduces a method to encase insulin-producing cells in collagen, creating a protective environment that helps the cells survive and function longer. By improving the success of cell-based therapies, this innovation could lead to more effective and lasting solutions for patients managing diabetes.
Antiviral and Antibacterial Disinfection Aero-Solution Using Edible Food Dyes
Inventor: Young Kim
Public health depends on safe and accessible ways to reduce infection risks. This patent uses edible food dyes to create a spray that kills viruses and bacteria. The solution is non-toxic, affordable and easy to apply, making it ideal for homes, hospitals and public spaces. It’s a simple idea with powerful potential to improve hygiene and safety.
Image Processing and Authentication of Unclonable Functions
Inventor: Young Kim
Cybersecurity is critical in a world where data drives everything. This patent introduces a way to create unique unclonable patterns for secure authentication. These patterns act like digital fingerprints, making it nearly impossible to counterfeit identifiers for devices or sensitive information. It’s a step toward stronger security in an increasingly connected world.
Information Code-Creating Method Using Fluorescent Silk
Inventor: Young Kim
Sustainability and security often go hand in hand. This patent uses fluorescent silk to embed secure codes in products and medical devices. The method is eco-friendly and adds a layer of protection against fraud, offering a creative solution that blends biology and technology.
Methods for Detecting Heart Rate, Respiration and Oxygen Saturation
Inventor: Jacqueline Linnes
Access to vital health data can save lives, especially in remote or resource-limited settings. This patent provides a simple way to measure heart rate, respiration and oxygen saturation without bulky equipment. By making health monitoring more portable and affordable, this innovation supports better care where it’s needed most.
Poroelastic Materials and Biosensors
Inventor: Chi Hwan Lee
Wearable technology is changing how we track health but comfort and accuracy remain challenges. This patent introduces soft porous materials for advanced biosensors. These materials improve flexibility and performance, paving the way for next-generation devices that monitor health seamlessly and comfortably.
Innovation That Matters
From improving diabetes care to advancing secure technology and health monitoring, these patents reflect Purdue BME’s commitment to solving problems that matter. Each invention is more than an idea—it’s a step toward a healthier, safer and more sustainable future.
