  • 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...

  • Design, Layout, and Testing of a Printed Circuit Board for Cyclic Voltammetry

    Creator:
    Harper, Karen
    Abstract:
    This project concerns the design, layout, assembly, debugging, and testing of a Printed Circuit Board (PCB) that autonomously, reliably, and effectively conducts Cyclic Voltammetry (CV) measurements. CV is an electrochemical procedure done to analyze, quantize, and visualize reversible reduction-oxidation reactions, often used in medical devices to monitor the levels of...

  • 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...

  • Viability of Single-Photon Avalanche Diodes for use in Pulse Oximetry

    Creator:
    Bialek, Hayden
    Abstract:
    Pulse Oximetry is a technology used ubiquitously across the medical field for measuring oxygen saturation and heart rate monitoring. In this project a system was developed to use a new technology for pulse oximetry: single-photon avalanche diodes (SPADs). This work outlines the development process and experimental results of a SPAD...

  • Prototyping of Thermoelectric Energy Harvesting Circuitry for IoT Devices

    Creator:
    Webb, Derek
    Abstract:
    Due to the advancement of incredibly low power microcontrollers and small form factor integrated circuits, energy harvesting can be considered as an alternative, low power source for remote ocean sensing and measurements. To demonstrate the effectiveness of harvesting thermoelectric energy contained in the temperature differential between ocean surface water and...

  • 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...

  • Wireless Multi-Sensor Patch for Wind Turbine Impact Detection

    Creator:
    Wilson, Calder
    Abstract:
    Bird and bat collisions with wind turbines are a problem that needs to be better quantified for its impact to be fully understood. This thesis documents portions of the design of a sensor patch module for use on wind turbines blades to detect impacts caused by birds and bats. This...

  • Evaluating TEG Energy Harvesting Capabilities Across Naturally Occurring Temperature Gradients

    Creator:
    Estenson, Alyssa H.
    Abstract:
    Thermoelectric generators (TEGs) have gained much popularity in the search for alternatives to clean sources to harvest energy. Given their capability to harness an electric potential given a temperature differential across their opposing faces, and the foreseeable prevalence of naturally and/or commonly occurring temperature gradients in multiple applications, TEGs are...

  • 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...
