Developed a novel microneedling-based lidocaine delivery device to enable rapid, uniform local anesthesia with minimal patient discomfort. Led the design of a single-use cartridge system featuring a hollow, adjustable-depth microneedle array fabricated from biocompatible polymer (PLA/PETG), integrating a modular fluid reservoir and precision rack-and-pinion mechanism for 0.5 mm depth increments...
Total hip arthroplasty is a common solution for osteoarthritis, yet many patients face revision surgeries due to aseptic loosening. To address this challenge, the project introduces an innovative hip implant that incorporates a drug-eluting mechanism—releasing growth factors like BMP-2—to enhance bone integration and joint stability. The design leverages advanced...
The project presents an innovative strategy to improve cochlear implant reliability by addressing two significant complications: infections caused by biofilm formation and insertional trauma during surgery. To combat infections, the design incorporates an antibacterial hydrogel coating made from sulfobetaine methacrylate (SBMA) and embedded with vancomycin, applied via a RAFT polymerization process. This coating is...
The research investigates whether five key blood markers (MCV, alkaline phosphatase, SGPT, SGOT, and GGT) can be used to classify levels of alcohol consumption and predict potential liver disorders. Unsupervised techniques such as Principal Component Analysis and k-means clustering were initially applied to assess the separability of drinking behaviors; however, these methods yielded limited differentiation. Subsequently, supervised learning models—including Logistic Regression, SVM, Random Forest...
This project focuses on designing, building, and testing a custom ball-bot—a robot that balances and moves on a spherical base. We used a Raspberry Pi 4, a Raspberry Pi Pico, an Inertial Measurement Unit (IMU), a battery, and three motor encoders arranged in a specific pattern to control five degrees of freedom. A PID controller, along with low-pass filters to reduce noise, was used to compute the motor torques needed to keep the ball-bot balanced...
The project implements a novel method to track ping pong balls bouncing on a flat surface by employing an array of four piezoelectric sensors mounted on a polycarbonate impact plate. High-speed signal processing is achieved using full-wave precision rectifiers and comparator circuits, which transform the analog signals from the piezos into digital logical signals. These signals are then rapidly processed by a Teensy V4.1 microcontroller...
