  • New Techniques for Multi-Channel Biosignal Acquisition and Low-Power, Low-Resistance-Measurement Systems

    Creator:
    Kim, Jinyong
    Abstract:
    Dense electrical recording of biosignals has been developed to provide spatial resolution and precise temporal information for health monitoring, diagnostics, and clinical research. However, more electrodes require more wires, and wiring density quickly becomes a limiting factor. To break this bottleneck, we proposed a frequency-division multiplexing (FDM) based architecture for...

  • Design and Implementation of a Modular Ocean Drifter Kit

    Creator:
    Green, Austin
    Abstract:
    Ocean Drifters are a low-cost and easy-to-use platform that are commonly used for studying ocean currents. With added interest in studying the ocean, emphasis has been taken to make it more accessible. A pilot course focused on introducing the topic of ocean sensing was announced. The HC 407 course will...

  • A comprehensive integration of first year engineering education

    Creator:
    Shuman, Matthew W.
    Abstract:
    Retention of engineering students is a problem for many universities, especially during the first year. The problem of introducing students to engineering while increasing retention rates has recently been addressed by many different universities. Implementing novel lab structures, adjusting the lecture to incorporate more effective teaching techniques, and using orientation...

  • Design and Modeling Techniques for Impedance Based Flow Cytometry

    Creator:
    Dawes, Jacob
    Abstract:
    Microfluidic devices have enabled lab-on-a-chip (LOC) systems that allow for complex sample analysis and preparation in a compact form factor. One technology that may benefit from a microfluidic approach and further miniaturization is flow cytometry. Flow cytometry is an analysis technique for enumerating and characterizing populations of cells; this is...

  • Autonomous Sensor Systems For Wind Turbine Blade Collision Detection

    Creator:
    Clocker, Kyle
    Abstract:
    Wind turbines serve an increasing proportion of total energy generation, with expanded onshore and offshore installations proceeding worldwide. Continued construction, expansion, and operation of wind energy installations must be managed in conjunction with effects on local and migratory wildlife, specifically bird and bat species that may be affected by wind...

  • Development of a Collision Detection Module for Avian and Bat Species on Wind Turbine

    Creator:
    Davis, Cassandra L.
    Abstract:
    Renewable energy technology continues to grow in popularity as countries aim to reduce greenhouse gas emissions. Land based and offshore wind turbines are one option for expanding renewable energy sources. However, as wind energy adoption increases, so does the need for enhanced monitoring of wind turbines’ potential effect on local...

  • Radiation Detection Module and Radioactive Isotope Identification System

    Creator:
    Ma, Naixuan
    Abstract:
    Radiation is part of our life. Most people may know a radioactive source is very dangerous. But there are very few situations people are exposed to uncontrolled radionuclides above background. A radioactive source can emit gamma rays which are the highest energy type in electromagnetic radiation.[2] Gamma rays are like...

  • CMOS Transducers and Programmable Interface Circuits for Resource-Efficient Sensing Applications

    Creator:
    Sengupta, Shaan
    Abstract:
    Modern sensors are complex systems comprising multiple sub-systems such as transducers, analog and mixed-signal interface circuits, digital processing circuits, and packaging. Over the last few decades, innovations in these sub-systems combined with their increased integration in complementary metal-oxide semiconductor (CMOS) processes have led to the rapid growth in sensors for...

  • CMOS-Integrated Single-Element Thermal Flow Sensors

    Creator:
    Clocker, Kyle
    Abstract:
    Flow rate sensors for in situ gas or liquid monitoring typically comprise multiple transducer elements, including a heater and one or more temperature sensors to measure the rate of heat energy removal by the flowing fluid. The need for multiple transducer elements limits feasibility of shrinking these sensors to microfluidic...

  • Energy Harvesting and Power Management Integrated Circuits for Self-Sustaining Wearables

    Creator:
    Bose, Soumya
    Abstract:
    Harvesting energy from ambient sources can provide power autonomy to energy efficient electronics and sensors. The last decade has seen a multitude of ways to scavenge energy from various sources like solar, thermal, electromagnetic, electrostatic, piezo-electric and many more. Thermal energy from human body heat is ubiquitous and can be...
