I led the PCB design and verification of a self-balancing data acquisition system for soft wearable sensors. In Altium Designer, I developed a high-sensitivity Wheatstone bridge circuit supporting firmware to enable balancing for various sensors. [Conference Publication: COMING SOON]
The system, built on an ESP32, integrated Python-based testing and MATLAB signal analysis to validate performance. We achieved a 390% sensitivity improvement in a 50% smaller package (7.52cm²). This project highlights my skills in circuit design, PCB layout, and end-to-end system validation.
As the sole researcher, I designed and validated a low-cost, LED-based near-infrared spectrometer for measuring tissue oxygenation and cell metabolism. The goal was to develop an affordable, compact alternative to fiber-based instruments, using a custom optode with LEDs and photodiodes integrated onto a flexible circuit.
The hardware design incorporated via-in-pad techniques and BGA components to support future package optimization. Firmware was validated through low-level SPI communication and custom register logic developed for the analog front-end. To assess system performance, I conducted a vascular-occlusion protocol to verify accurate measurement of the hemodynamic response.
