Number of positions: 1

We are utilizing low-cost rapid diagnostics to develop portable, non-invasive, glucose sensing and monitoring devices for diabetic patients. Currently, we are measuring glucose concentrations from exhaled breath condensates (EBC) which has historically required breathing into a device cooled by ice to condense moisture. Students on this project are expected to perform mentored independent research to develop an electrically cooled, portable, miniaturized condenser that can collect 10 µl of EBC within 30 seconds and selectively condenses only breath containing carbon dioxide/glucose while quantifying the total volume of air exhaled. You will gain hands on experience in instrumentation development, bioassays, and control systems.

 

Experimental testing and validation of P-band bistatic remote sensing of soil moisture

Research categories:  Agricultural, Aerospace Engineering, Electronics, Environmental Science, Physical Science
School/Dept.: AAE
Professor: James Garrison
Preferred major(s): Electrical engineering, physics, aerospace engineering
Desired experience:   Basic signal processing, linear systems. Experience in working with electronic equipment and computer programming. Some knowledge of statistics helpful.
Number of positions: 1

This activity is part of a larger research project, funded under the NASA Instrument Incubator Program, to develop and test a prototype for a new instrument for the remote sensing of sub-surface, or “root-zone” soil moisture. This is an important quantity to measure for our understanding of the water cycle and for practical applications in agricultural forecasting. The innovative technology in this instrument, is the use of “signals of opportunity” (SoOp’s), which are reflections of communication satellite transmissions. In contrast to active radar remote sensing, a SoOp instrument will be much smaller and lower power, as it does not need an transmitter. SoOp also allows measurements to be made in frequency bands that are not protected for scientific use, essentially making the entire microwave spectrum available for remote sensing.

In this particular application, we will use communication signals in P-band (230-270 MHz), which can penetrate the soil to several decimeters. For comparison, satellite instruments today operate in L-band which has a penetration depth of ~5 cm.

On this project, a SURF student would learn the fundamental physical models, apply them in simulations, to predict the sensitivity of the P-band reflectivity to soil moisture variation and instrument calibration. The student would also assist in assembling instrumentation for ground experimentation, processing the data and interpreting the results.

Students should have some experience with electronic equipment and computer programming, and know basic signal processing and linear systems. An interest in Earth and environmental sciences is desirable.

 

Hotspot imaging analysis for experimental cancer

Research categories:  Bioscience/Biomedical, Computational/Mathematical, Electronics, Life Science, Physical Science
School/Dept.: Weldon School of Biomedical Engineering
Professor: Young Kim
Preferred major(s): BME, ECE, ME, Physics
Desired experience:   Imaging analysis, hardware interfacing, optical bench work, optical imaging
Number of positions: 1

Our group has recently developed an optical microvascular imaging platform to predict tumor formation in skin cancer. The primary goal of this project is to examine cancer prevention effects of skin resurfacing on experimental skin cancer, by comparing microvascular imaging with aminolevulinic acid-induced fluorescence imaging in animal models. While fractional ablative lasers are extensively used for cosmetic/aesthetic purposes, we will utilize this light-based treatment modality to prevent against neoplastic formation, because stromal alterations during early carcinogenesis serve as fertile tissue environments for subsequent tumor development. In preliminary data in mice, focal areas of persistent inflammatory angiogenesis are highly reliable predictors of future tumor development. To accurately determine cancer prevention effects, we will combine the two imaging modalities in small animal settings and visualize alterations in the spatial extents of detailed microvascularity. During this research, students will be able to get familiarized with 1) biophotonics technologies, 2) imaging processing, 3) basic cancer biology. This study could have a translational commercial impact, as this non-invasive instrument could be used clinically to assess an individual's risk of future tumor formation and to provide an early assessment of the effectiveness of current and emerging therapeutic and preventive treatment strategies.

 

Nano-Piezotronics for Smarter Electronics

Research categories:  Bioscience/Biomedical, Chemical, Electronics, Industrial Engineering, Material Science and Engineering, Mechanical Systems, Nanotechnology, Physical Science
School/Dept.: Industrial Engineering
Professor: Wenzhuo Wu
Preferred major(s): Mechanical, Electrical, Materials, Biomedical, Industrial Engineering
Number of positions: 1

The seamless and adaptive interactions between electronics and their environment (e.g. the human body) are crucial for advancing emerging technologies e.g. wearable devices, implantable sensors, and novel surgical tools. Non-electrical stimuli, e.g. mechanical agitations, are ubiquitous and abundant in these applications for interacting with the electronics. Current scheme of operation not only requires complex integration of heterogeneous components, but also lacks direct interfacing between electronics and mechanical actuations.

Piezotronics is an emerging field in nanomaterials research and offers novel means of manipulating electronic processes via dynamically tunable strain. In this research, the SURF students will develop flexible and transparent piezotronic nanowires transistors for active and adaptive bio-electronics sensing and interfacing. The device is capable of self-powered active sensing by converting mechanical stimulations into electrical controlling signals without applied bias, which emulates the physiological operations of mechanoreceptors in biological entities, e.g. hair cells in the cochlea.

This project is scientifically novel with transformative impact because it not only dramatically advances fundamental understanding of the emerging research in piezotronics, but also enables new opportunities in designing “smarter” electronics that are capable of interacting with the environment seamlessly and adaptively, which is not available in existing technologies, for societally pervasive applications in intelligent wearable devices, surgical tools and bio-probes. The SURF student will work with two PhD students on the nanomaterials synthesis, nanodevices fabrication and measurement.

Soft Sensors for State Estimation of Robotic Manipulators

Research categories:  Electronics, Material Science and Engineering, Mechanical Systems
School/Dept.: Mechanical Engineering
Professor: Rebecca Kramer
Preferred major(s): ME, EE, MSE
Number of positions: 1

Soft robotics is a research field focused on developing non-traditional robotic systems using materials that are flexible and stretchable. In contrast, many traditional robots are composed of rigid linkages that are controlled to move discrete distances and angles. Because of the of the flexible materials comprising soft robots, they are capable of creating and/or surviving deformations that are many times larger than those found in rigid systems. As a result, the actuation, sensing and control needs differ greatly for soft robotic systems when compared to the traditional robotic systems.

For this project, a 1 degree-of-freedom pneumatic arm will be instrumented with a network of strain gauges. The arm will be actuated using pneumatics. State estimation and thus, control, of the arm will be accomplished by instrumenting the surface of the arm with a network of sensors composed of highly stretchable elastomer strain gauges. This project will require the design, manufacture and integration of sensors onto the pneumatic arm. The effect of different types and magnitudes of loading on the sensor output will be studied and used to iterate the design of the sensor network.

School/Dept.: Industrial Engineering
Professor: Wenzhuo Wu
Preferred major(s): Biomedical, Mechanical, Electrical, Materials, Industrial Engineering
Number of positions: 1

Triboelectric nanogenerator (TENG) has emerged as a promising technology for efficiently harvesting mechanical energy due to high conversion efficiency, low fabrication cost, and broad choice of materials. TENGs utilize contact electrification to generate surface charges and convert mechanical energy into electricity from contact and separation between triboelectric layers. Apart from material selection and device structure, one crucial factor affecting the performance of contact electrification process is materials properties and topography of triboelectric contact surfaces. In this project, we will manufacture large scale TENG with modifiable properties at high production rate. These flexible TENGs will be used to harvest mechanical energy from human body, e.g. muscle stretching/motion, and from ambient environment, e.g. wind, raindrops. The converted electricity can be utilized to power small electronic devices, e.g. sensors and processers. The TENGs can also function as self-powered wearable sensors to quantitatively track human motion and monitor posture. The student will work with our PhD students on the nanomaterials synthesis, nanodevices fabrication and measurement.
