    • ESE Ph.D. Thesis Defense: “Design and optimization of laminated metallic cores for high-frequency transformers and inductors”

    /
    Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    High-frequency power converters increasingly require magnetic components that are compact, efficient, and compatible with advanced integration. Conventional ferrites face limitations in scaling and high-frequency performance. This work introduces laminated NiFe magnetic structures fabricated through CMOS-compatible multilayer electroplating as a promising alternative. The materials and fabrication approach are demonstrated through silicon TSV inductors and transformers, PCB-integrated […]

    ESE Ph.D. Thesis Defense: “Microfabricated devices for in-vivo sensing for mitochondrial assessment”

    /
    Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Monitoring of oxygen concentration in biological tissues is essential for understanding cellular metabolism, mitochondrial function, and tissue regeneration. Mitochondrial dysfunction is linked to a wide range of metabolic and degenerative diseases, yet current diagnostic approaches lack the capability to continuously measure oxygen and metabolite dynamics in vivo. This work introduces an implantable electrochemical sensor platform […]

    • ESE PhD Thesis Defense – “Design and Characterization of AlScN-Based Ferroelectric Devices for Non-Volatile Memory Applications”

    /
    Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Ferroelectric materials have emerged as promising candidates for next-generation non-volatile memory technologies due to their intrinsic remnant polarization and fast switching dynamics. Among them, aluminum scandium nitride (AlScN) stands out for its CMOS compatibility, low growth temperature, exceptional thermal stability and high remnant polarization compared to conventional perovskite and hafnia-based ferroelectrics. In this dissertation, I […]

    • ESE Guest Seminar: “On-Device Probabilistic AI: From Gaussian Transistors to Light-Driven Spike Encoding”

    /
    Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Emerging edge AI systems call for device-level approaches that are inherently low-power, secure, and capable of managing uncertainty. In this talk, I will share our recent exploratory efforts toward realizing on-device probabilistic intelligence using custom-designed semiconductor devices. I will introduce Gaussian transistors that support analog Gaussian activation and probabilistic inference by harnessing device-level variability. These […]

    • CBE Doctoral Dissertation Defense: “MEMS-Based Electrochemical Power Sources for Extended Operational Duration of Micro Unmanned Vehicles” (Yanghang Huang)

    /
    Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Abstract: Micro unmanned vehicles, defined as 25-gram to 5-kg in weight, are increasingly being utilized in applications such as search and rescue or agricultural monitoring. Such vehicles are typically powered with lithium-ion batteries. However, vehicle operational efficiency and capability are often compromised by the limited energy density of these batteries, resulting in short operational duration. […]

    • ESE PhD Thesis Defense: “Low Noise and Low Power Front-end Circuit Design for Bio-Signal Recordings”

    /
    Room 221, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Bio-signals in living objects are the signals thatcarry physiological information from one part of the body to another. Studying bio-signals can extract data that maps health status or body activities for medical purposes. Implantable and wearable devices of small volume for measuring different bio-signals are desired for medical applications where the devices measure the signals […]
