Designed and developed a miniature, wearable and wireless ECG/Motion data acquisition platform using a commercially available ARM Cortex M0 powered BTLE SoC. I was responsible for the firmware development, miniature PCB design, conductive fabric electrode interface, ECG instrumentation amplifier and management of the iOS app development team. The focus of this project was to develop a complete, low cost, lightweight, modular platform offering a basic monitoring capabilities. The system was also designed to be able to interface with a variety of potential sensors both analog and digital. During the iterative design process I performed exhaustive troubleshooting and debugging on the firmware and physical hardware portions of the system. I also interacted extensively with vendors, manufacturers and designers, both in the US and overseas.Worked with two other students to create an SoC in TSMC 65nm for biomedical monitoring applications. I assisted in the initial research, partitioning and planning of the system architecture and I stayed highly involved with the project through the design, validation and testing phases. I was responsible for the implementation and validation of an Arm Cortex M0, adjacent SRAM and the custom programmer and AHB-lite interfaces. I used an efficient shell and TCL script driven workflow which included the operation of extensive test benches at the register-transfer, gate and post-PnR levels. This work flow also included scripting for the quick and effective use of digital place and route software. I created the PCBs used for the testing and validation of the SoC and operated the requisite lab equipment.Assisted with the testing and verification of an energy harvesting SoC in TSMC 65nm created by members of the group. Developed an ultra-miniature, multi-sensor platform utilizing flexible PCBs which was also paired with the SoC.
