Intro for Web Viewers
Hello!
Thanks for taking a moment to check out this short Powerpoint. In it I cover a
few projects that I have worked on during my academic career.
The first project that I cover is a lab assignment that I carried out during my
sophomore year at the University of Connecticut
The second project is my Capstone project from my senior year. The intent of
this web presentation is to give a brief overview of some of the things I have
worked on and where my interests lie.
Thanks for viewing! I am looking forward to giving this presentation to you in
person.

Sensors and Data
Piezoelectric Actuator Lab







Used a motor with a fine travel
range of 25 micrometers
Inputted 5 V signal at 5hz
Measured movement with Linear
Variable Displacement Transducer
(LVDT) and National Instruments
LabView
Used filters to account for noise
Looked for 5hz signal in LabView

3

Sensors and Data
Results



Focus was on windowing and
signal processing
Used Fourier Transform to find
constituent frequencies of
measured signal




Various waveforms
Various sampling frequencies

Other Piezoelectric Applications
Harvard Robobee





Meso-scale flying robot
Two piezoelectric components
control each wing
Weight less than .1g
Currently wired

UConn Senior Design
Overview







Year-long design project
Corporate Sponsor
gives “donation” of
~$10,000
Teams of students work
to solve industry
problems
Projects are displayed
at UConn School of
Engineering
“Demonstration Day”

Automation of a Taping Process







Goal was to automate the
application of masking tape
Masked parts to be plated
(chrome, anodized, acid-etching)
MRO process – variable part
geometry
Machine has to accept range of
part sizes
Successful outcome
