THE DETAILS:
Dragon Spectral: Hyperspectral Imaging Devices through H-PDLC Optical filters
Lead Engineer
H-PDLC, holographically formed polymer dispersed liquid crystal, is a thin film of polymer and liquid crystal, which is treated with a split laser to form a reflective Bragg grating. This creates a simple and cost effective high quality optical filters, beam steerers, and reflectors for display and sensor applications. As the lead engineer of Dragon Spectral, I develop the electronic drivers which allow for the optical switching of the specific wavelengths of the filter. My tasks also include developing new cost-effective optical switching structures for applications which current mechanical filters are utilized.

Textile-Based Robotics: Shape Memory Alloy Actuator Integration with Woven and Knitted Fabrics
Ph.D. Candidate
Supervisor: Adam Fontecchio, Ph.D.
Currently, the field of SMA-fabric integration is limited with the research focused on aesthetic and commercial needs. This work will strive to focus on the robotic, medical, and industrial aspects of the integration through the development of a woven SMA-fabric massaging structure. Specific SMA working parameters will be experimentally researched and modeled. These parameters include transformation temperature, power consumption, bending force and displacement. These parameters are controlled through element combination, heat treatment and dimensions of the SMA wire segments. The main outcomes of the proposed research are a bending force study of 60 mm SMA wire segments by themselves, as a yarn with a cotton sheath and within a woven hybrid cotton & SMA-core yarn fabric. These main objective lead to the development of a 6-segmented woven massaging ring that is actuated via a joule-heated control system. This progression will be used towards the development of a fully woven massaging sock or sleeve to prevent blood clots.

Nanophotonics+ Lab: Magnetic Nanoparticle Epoxy
Master Student
While ferro-nanoparticles can be manipulated on the micro and nano-scale for different purposes, this research focuses down to manipulation with in a particular substrate. By creating magnetic “Ferro fluid” based glue, glue particles can be manipulated and placed on the nano-scale and then UV cured to give precise placement of glue. The particles are first coated in a surfactant to provide them with space between them and eliminate large agglomerates. Then, using a carrier fluid of optical glue the magnetic nano epoxy could be directed via an external magnet and carrier the optical glue to precise desired locations.

ExCITe Center: Belly Band (Textile-based) Monitor Sensor and Graphical User Interface
Research Assistant
The Belly Band is a device that goes around an expected mother’s stomach as a fetal monitor for things such as heart and breathing rate. I worked on the external control system for the device using Arduinos. Starting with a conductive fabric, the resistivity of the textile changed due to the stretched or relaxed state. Therefore by monitoring the stretch of the fabric, even at small degrees, a heart/breathing rate monitor was created using an arduino and LCD. A graphical user interface, GUI, showed the increase and decrease in the resistivity. A MatLab GUI program was also created performing the necessary calculators for the monitoring traits.

Printable-Flexible Antennas
Co-op Student
With an affiliation between PChem Inc. and Drexel University I worked with a machine called the N-Script. This is an adapted CNC machine that instead of the tip being a drill it is a pen that distributes conductive inks. I coded in MasterCam and NC editor to control the path and flow rates of the machine.

Fiber Optic Control System for Carbon-Nanotube Pipettes
STAR (Students Tackling Advanced Research) Scholar
For this program, I conducted research on carbon nanotube-glass pipettes. The objective of the project was to pull a glass pipette down to less than 10 microns and then attach a carbon nanotube on the tip of it. This would allow for entry into the nucleus of a cell and take out content. On second part of this project I researched ways to push content down the carbon nanotube pipette using a fiber optic system. By creating a pressure build up inside the back end of the pipette material could be pushed out of the tip.

MEMS Mirror Voltage Control
Drexel High School Mentorship Scholar
Supervisor: Tim Kurzweg, Ph.D.
Learning to work in a lab with graduate students for two weeks in high school was my first taste of research. I worked with an array of micro electro-mechanical mirror systems. By applying a particular voltage across the MEMS mirrors it affected the tilt. It was a system being used to increase resolution off of taking a picture from a camera off of the array of mirrors.
