Controlling Defects in CVD Grown Graphene : Device Application Perspective
(2017-12-06)Necessity is the mother of all inventions. With Si hitting the speed bottleneck, newer materials to replace Si are being sought out. The ex-foliation based experiments on graphene by Geim and Novoselov at this point was ... -
Cricket Inspired micro Speakers
MEMS technology has ushered in a new era of miniaturized sensors and actuators. Many smart devices and systems are being developed using these sensors. Home automation is now a widespread reality owing to the development ... -
Development and Performance Evaluation of the Flapping Wing with In-situ Piezoceramic Actuator
Unmanned Aerial Vehicles (UAV) are essentially automatic flight vehicles having dimensions, wingspan and airspeed, smaller than the conventional aerial vehicles. UAVs are employed widely in applications such as surveillance ... -
Development of High-Performance Piezoelectric Micromachined Transducers for Near Ultrasound
Near-ultrasound refers to sound with frequencies just above the range of human hearing, from about 18 to 40 kHz. This band is rarely used for typical ultrasound applications and is ignored for all except the most demanding ... -
Development of Microsystem Platforms Towards Cancer Diagnostics and Therapeutics
This thesis explores the development and application of microsystems to advance our understanding of disease biology. The overarching goal is to enhance diagnostic and therapeutic strategies through precise and physiologically ... -
Development of Piezoelectric Ultrasound Transducers for Novel Applications
Ultrasound is a scientific miracle with its magical contributions in almost all the branches of modern-day technology. It all started with the discovery of the ‘piezoelectric effect’ by the Curie brothers, who demonstrated ... -
Development of PZT Based PiezoMEMS for Fluid Property Sensing
The research on Microelectromechanical Systems (MEMS) has resulted in several practical applications which have revolutionised the fi eld of sensors and actuators. Piezoresistive pressure sensors, capacitive micro-mirror ... -
Electric Field Induced Phenomena: Mass Flow and Chemical Reaction-based Patterning
Numerous electric field induced phenomena have been studied, for long, at various length scales. In particular, a concentrated electric field applied across a conductor, or equivalently an electric current of very high ... -
Exploring One-dimensional Micromechanical Resonators with Residual Stresses for Potential Sensing Applications and Measurement of Mechanical Properties
Recently the domain of microelectromechanical systems (MEMS) has seen an unprecedented rise in use of varieties of new materials other than the conventional silicon and related materials originally borrowed from semiconductor ... -
Study and Control of Electromigration Driven Material Transport for Applications in Nanofabrication and Patterning
Transfer of mass energy is at the heart of many physical processes that form the backbone of modern science and technology. Transport studies help in understanding these processes and reveal the underlying physics that ... -
Study of Micro-and Nano-Scale Transport of Liquid Metal on Thin Solid Films
In recent times, researchers have found potential in using liquid metals in broad-spectrum applications such as processing ceramics, stretchable electronics, 3D printing, coolant technology, energy storage, and many others. ... -
Towards Design and Development of Indigenous Rate-Grade MEMS Gyroscopes
Gyroscopes sense angular speed of the body on which they are mounted. Traditional mechanical gyroscopes are big, bulky, expensive, and hence limited to a few applications. With the advent of Micro-Electro-Mechanical Systems ... -
Towards Design, Fabrication, Packaging, Integration, and Characterization of High-Performance MEMS Gyroscopes
MEMS vibratory gyroscopes are used to measure the angular rate of a body by sensing the Coriolis force induced motion of the sensing element vibrating in a rotating frame of reference. MEMS gyroscopes find use in a wide ... -
Towards the Development of MEMS g-Switches
Accelerometers are sensors that measure and record the acceleration of an object in motion. They typically contain spring and mass elements that are set into vibration upon any impressed acceleration. The characteristics ...
