Sample Personal Statement for Electronic Materials and Devices
To realize high-precision time control of the PC parallel port
through software programs was once prophesized by my advisor as a
mission impossible. Prior to this, a talented student in XX University
spent an entire semester attempting to work out this problem but he
ended up in failure for the sheer difficulty of the task. In
retrospect, it was the very negative attitude of my advisor and the
failure of my predecessor that aroused my determination to make a try
on my own. Through carefully studying a large amount of technical
materials that I had collected, I carried extensive theoretical
analysis and cautious calculation. By exploiting the strong power of
VC++ and the high speed of the assembler language, I spent only three
weeks and achieved time control of the PC parallel port with high
precision on the order of microsecond. Based on the research findings
in this project and on other projects, I submitted my thesis entitled
XX, which was rated by the Thesis Evaluation Committee as “a
pioneering thesis that deals with a challenging subject, yet
demonstrating a high level of technical realization.”
The success of my undergraduate graduation project and thesis
reinforced my resolution to seek further development in electrical
engineering and in automation. After being successfully matriculated
into the Master’s program at the College of Electrical Engineering and
Automation of XX University, majoring in Electrical Machinery and
Electrical Appliance Automation, I have devoted myself to serious
academic pursuit with much greater enthusiasm. My coursework in The
Control Theory of Electrical Machinery, Modern Design Theory of
Electrical Machinery, Modern Testing Technology of Electrical
Machinery and other subjects has enabled me to lay a solid theoretical
foundation whereas courses like Digital Simulation Technology of
Electrical Machinery, the Matric Analysis of Electrical Machinery and
the Instantaneous Changes & Energy Conversion of Electrical Machinery
helped me develop professional thinking and techniques. With an
overall GPA of 81.5 and even better performance in the core courses, I
have been awarded the scholarships of the University and honored as
Outstanding Student.
On the strengths of my firm buildup in control theory and excellent
ability in circuitry design, I came to the attention of Prof. XXX, a
leading specialist in the field of ultrasonic motor, who recruited me
into his research group. With this, I started actual research half a
year earlier than other students. So far, I have participated in two
research projects XX, and XX, one sponsored by XX and the other by XX.
Based on my research findings from those projects, I have contributed
a total of five research papers to the country’s leading technical
journals like Journal of Electrical Motor Engineering. Among my five
papers, XX, and XX have been published. The other three papers, XX,
XX, and XX have been accepted and scheduled for publication in the
later half of this year.
The conventional ultrasonic motor transmits energy through friction
and it poses numerous limitations in application. In order to achieve
important breakthroughs, we conceived the idea of introducing liquid
into the space between the stator and the rotator. I decided that the
liquid-media ultrasonic motor would be the focus of my research during
my Master’s program, which is also part of the key research project
led by supervisor as a larger program sponsored by XX. In view of all
the technical literature available, the applied research worldwide in
this field has been rather scanty, some are very simplistic while
others are excessively empirical. There is marked discrepancy between
theoretical research and practical application. For this reason, I
self-studied a number of important subjects including Mechanics of
Viscous Fluids, Fundamental of Acoustics, Non-Linear Acoustics, and
Ultrasonic Motor and made in-depth study of the technical literature
published in English by western scholars. I completed the derivation
of equation regarding the distribution of speed in the liquid field of
the motor and regarding the distribution in the acoustic field. In
this process, I proposed my theoretical design.
As research on the liquid-media ultrasonic motor is a totally new
subject in the Chinese academia, the major difficulty I have
encountered is the lack sophisticated experiment equipment.
Nevertheless, I have to make my utmost efforts to ensure the accuracy
of my data. Therefore, I have extensively consulted the technical
parameters of various electrical and electronic components both at
home and abroad, and made necessary improvements in the existing
facilities of my lab in accordance with the requirements of our
experiment plans. Through my independent efforts, I made the motor
control and the driving circuits. Moved by my dedication, my advisor
and other senior professors have offered to help me with their
knowledge in their respective fields. Some imparted me their useful
expertise of experiment, even Prof. XX who was far away in XX
Technological University maintained constant contact with me through
e-mail to explicate specific details and clarify my problems.
With their support, I have performed detailed analysis and
verification on the saturated flow velocity of the liquid-media
electrical motor and its effect on the motor characteristics,
determining the relationship between the motor’s rotational speed,
drive frequency and drive voltage. My paper XX, which is retrieved by
the EI, describes the structure and the working principles of the
motor, the realization of the drive circuit, and provides theoretical
and experimental analysis of the saturated flow velocity.
Ultrasonic motor is much superior to conventional motor in its
low-speed big torque, short response time, and electromagnetic
resistance. The research on ultrasonic motor started more than 20
years ago but so far few mature products have been produced. The only
instance of the application of this technology is found in the Cannon
camera. However, when problems of the motor’s complicated structure
and high cost are worked out, ultrasonic motor will enjoy an unlimited
prospect of commercial production.
I would like to apply for a Ph. D. program in Electrical Materials and
Devices from your esteemed university. I believe I am a worthy
candidate for your program. My undergraduate program in electrical
automation has given me a solid foundation in control and circuitry
while my Master’s program in Electrical Machinery and Electrical
Appliance Automation has led me to pioneering research of liquid-media
ultrasonic motor. I have a relatively strong capacity to carry out
independent research and I have interdisciplinary knowledge across
majoring fields of electrical engineering.
In my proposed program, I would like to pursue my research interests
in piezo-electrics, sensors and transducers and ultrasonic motor. In
terms of the research on the ultrasonic motor, I would focus on the
research of the new-type ultrasonic motor, ultrasonic motor control,
and the development of small-scale ultrasonic motor for commercial
purposes. It is my belief that your program, by exposing me to the
latest technology in electronic materials and to the development of
novel device structures and manufacturing methods, device and circuit
simulation and modeling, device and material characterization, will
significantly facilitate my research on the ultrasonic motor and in
other related fields. For this reason, I expect that you can give
serious consideration to my application. |
