  • Design of 3D-Printed Soft Pneunet Actuator for Robotic Fruit Harvesting

    Creator:
    Wilhelm, Lissette J. H.
    Abstract:
    This work details the development of 3D printed TPU pneunet actuators for use in apple picking for agricultural soft robotics. These actuators increase the force capabilities of soft pneunets and simplify manufacturing. Grippers based on these actuators are ideal for apple picking because they are compliant, yet exert sufficient force...

  • Field-use electrochemical sensors for detection of carbamazepine in saliva and water

    Creator:
    Minzlaff, Jade
    Abstract:
    The anticonvulsant drug carbamazepine (CBZ) is a commonly prescribed drug that is used to treat patients with neurological disorders including epilepsy and bi-polar disorder. CBZ has a narrow range of efficacy: Below the therapeutic dose, seizures and other conditions are not controlled, and above the recommended window, patients experience side...

  • Non-enzymatic electrochemical sensors based on functionalized nanomaterials

    Creator:
    Wu, Bo
    Abstract:
    Unlike other biosensing, electrochemical biosensor has the advantages of robustness, easy miniaturization, excellent detection limits, and capability in handling small analyte volumes. The detection selectivity of the electrochemical biosensors is mainly supported by bioreceptors. However, these receptors always suffer from the performance variation caused by the environment and the thermal-...

  • Per- and Polyfluoroalkyl Substances (PFAS): Protein Binding and Partitioning and Sorption in Light Non-Aqueous Phase Liquids

    Creator:
    Christie, Emerson C.
    Abstract:
    Per- and polyfluoroalkyl substances (PFAS) are anthropogenic surfactants that have recently been identified as persistent organic pollutants. These so called “Forever Chemicals” have been detected in drinking waters, ground waters, soils, and consumer and industrial products globally; with environmental impacts stretching into the artic, far from known PFAS sources. The...

  • Sensor Interface Circuit Design towards CMOS Scaling

    Creator:
    Liu, Jialin
    Abstract:
    Sensor system plays an important role in connecting everything including human body to the electrical information systems that we have built and that we are going to build, to make the world more intelligent and efficient. One of the key propulsive forces behind these emerging techniques is CMOS scaling that...

  • SIMstat: Wireless, Highly-Reconfigurable Electrochemical Analog Front-End for Point-of-Care Diagnostics and Continuous Monitoring

    Creator:
    Cook, Jacob M.
    Abstract:
    Within the past decade, the continued-scaling of CMOS processes and improvements in industry mixed-signal integrated-circuit designs have enabled a rapid decrease in the cost, form-factor, and power for point-of-care diagnostics and electrochemical instrumentation. Similarly, advances in low-power RF designs have prompted entire System-on-Modules supporting widely varied Internet-of-Things (IoT) applications. The...

  • Point-of-care and wearable sensors for non-invasive stress hormone detection with molecularly imprinted techniques

    Creator:
    Yeasmin, Sanjida
    Abstract:
    Rapid and sensitive detection of stress hormones, such as cortisol and dehydroepiandrosterone (DHEA), can benefit the diagnosis of diseases related to adrenal gland disorders, post-traumatic stress disorders, chronic fatigue syndrome, and more. Stress hormones fluctuate in a circadian rhythm, the highest in the early morning and the lowest at night;...

  • Imepdance Sensing Techniques for Integrated Circuits Sensor Applications

    Creator:
    Shen, Boyu
    Abstract:
    Impedance measurements are increasingly demanded in modern CMOS sensing systems as impedance is the most common electrical signal obtained from sensors, delivering physical, chemical and biomedical quantity changes. Impedance sensing for wide interested frequency, broad dynamic range, and various sensor interfaces has numerous challenges, especially targeted in CMOS miniaturization with...

  • Development of a Novel MEMS Thermal Sensor Array for Pebble Bed HTGRs

    Creator:
    Hertel, Matthew A.
    Abstract:
    A novel high temperature thermal instrument is proposed, which utilizes a dual-sensing platinum resistor encased in a mono-crystalline alpha-alumina (sapphire) substrate. The instrument is comprised of four platinum trace elements, oriented with 90° rotational symmetry atop a 1120 oriented crystal lattice substrate. All four of these sensors measure temperature directly...
