About Me.
Hi! I’m Hanlin Lyu, a junior Biomedical Engineering student at Rose-Hulman Institute of Technology with a passion for bridging the gap between medical innovation and real-world application. As an international student from China, I bring a global perspective to problem-solving, coupled with hands-on experience in biomaterials, FDA regulatory affairs, and medical device design.
Throughout my academic journey, I’ve focused on developing solutions that improve patient outcomes, with projects ranging from pacemaker materials research to the design of controlled drug delivery systems. I’m also experienced in digital signal processing, and I’m currently developing innovative healthcare solutions.
I’m driven by curiosity, collaboration, and the belief that engineering can make healthcare more accessible and effective for everyone.
Let’s connect and create something impactful!
Project
Simulated Glucometer
As part of our Biomedical Engineering project at Rose-Hulman, my team and I developed a simulated glucometer to demonstrate how blood glucose monitoring works. Here's a closer look at the process and technology behind it:
⚙️ How It Works
-
Lancing System Simulation
In real glucometers, a small lancet is used to prick the skin and obtain a drop of blood. In our simulation, we mimic this step without actual blood to provide a safe, user-friendly demonstration. -
Testing Strip Simulation
Normally, glucose in the blood reacts with chemicals on a testing strip, creating an electrical current proportional to glucose concentration. In our project, we simulate this chemical reaction by using variable resistances to represent different glucose levels. -
Signal Detection & Processing
The simulated electrical signal is sent to an Arduino microcontroller. The Arduino processes the input voltage—representing glucose concentration—and converts it into a digital reading. -
Data Display on Interface
The processed data is transmitted to a computer interface where the glucose level is clearly displayed. We designed the interface to resemble commercial glucometers, with an emphasis on clarity and usability. -
Device Enclosure
We housed all components in a custom shell to make the device look and feel like a real glucometer, emphasizing ergonomics and portability. -
Data Transmission Potential
While our prototype uses wired communication, the design includes considerations for wireless data transmission to smartphones or other health management systems in future iterations.
💡 Why This Matters
Understanding how glucometers function is key for biomedical engineers focused on patient-centered design and medical device innovation. Our simulated device provides a safe, educational tool for teaching the mechanics behind this life-saving technology—without the need for invasive procedures.
