Ashwin Seshia is a scientist and engineer, known for his work in the fields of microelectromechanical systems (MEMS) and nanotechnology. He is currently the Professor of Microsystems Technology at the University of Cambridge.
Seshia received his BTech degree in Engineering Physics from IIT Bombay in 1996. He then went to study in the United States until 2002, where he received his MS and PhD degrees in Electrical Engineering and Computer Science from the University of California, Berkeley. [1]
Seshia has become known for his work in the field of microelectromechanical systems (MEMS) and sensor technology. [2] He is currently a professor of Microsystems Technology at the University of Cambridge, where he leads the Micro and Nanoengineering Group within the Department of Engineering. Seshia's research focuses on the design, fabrication, and application of MEMS devices, which are tiny integrated devices or systems that combine electrical and mechanical components at a very small scale.
One of his notable areas of expertise is developing resonant MEMS devices, particularly resonant sensors and actuators. These devices use the mechanical vibrations of microstructures to sense various physical quantities such as acceleration, pressure, and temperature with high sensitivity and accuracy. [3] He work in this field has led to him receiving numerous industry awards and recognition. In 2014, he was awarded The Royal Academy of Engineering Silver Medal for his work in the field of nanotechnology. [4]
MEMS is the technology of microscopic devices incorporating both electronic and moving parts. MEMS are made up of components between 1 and 100 micrometres in size, and MEMS devices generally range in size from 20 micrometres to a millimetre, although components arranged in arrays can be more than 1000 mm2. They usually consist of a central unit that processes data and several components that interact with the surroundings.
Microfabrication is the process of fabricating miniature structures of micrometre scales and smaller. Historically, the earliest microfabrication processes were used for integrated circuit fabrication, also known as "semiconductor manufacturing" or "semiconductor device fabrication". In the last two decades, microelectromechanical systems (MEMS), microsystems, micromachines and their subfields have re-used, adapted or extended microfabrication methods. These subfields include microfluidics/lab-on-a-chip, optical MEMS, RF MEMS, PowerMEMS, BioMEMS and their extension into nanoscale. The production of flat-panel displays and solar cells also uses similar techniques.
Micropower describes the use of very small electric generators and prime movers or devices to convert heat or motion to electricity, for use close to the generator. The generator is typically integrated with microelectronic devices and produces "several watts of power or less." These devices offer the promise of a power source for portable electronic devices which is lighter weight and has a longer operating time than batteries.
Rudra Pratap is an Indian academician and the vice-chancellor of Plaksha University, Mohali. Previously, he was a professor of Mechanical Engineering at the Indian Institute of Science (IISc), Bangalore. Among other research interests, he works in the field of Microelectromechanical systems (MEMS) and used to head India's first research lab in the field of Microelectromechanical systems, the CranesSci MEMS Lab at Indian Institute of Science, Bangalore. His book on MATLAB Getting Started with MATLAB 7 is popular among the students of engineering. He is also the Chair for the Centre of Nanoscience and Engineering (CeNSE).
Electromechanics combines processes and procedures drawn from electrical engineering and mechanical engineering. Electromechanics focuses on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other. This process is especially prominent in systems such as those of DC or AC rotating electrical machines which can be designed and operated to generate power from a mechanical process (generator) or used to power a mechanical effect (motor). Electrical engineering in this context also encompasses electronics engineering.
MEMS for in situ mechanical characterization refers to microelectromechanical systems (MEMS) used to measure the mechanical properties of nanoscale specimens such as nanowires, nanorods, whiskers, nanotubes and thin films. They distinguish themselves from other methods of nanomechanical testing because the sensing and actuation mechanisms are embedded and/or co-fabricated in the microsystem, providing—in the majority of cases—greater sensitivity and precision.

While at Georgia Tech, he also held multiple administrative positions, including Senior Vice Provost for Research and Innovation; Acting Director of the Georgia Electronic Design Center; and Inaugural Executive Director of Georgia Tech's Institute for Electronics and Nanotechnology. He was editor in chief of the Journal of Micromechanics and Microengineering (JMM), and currently serves on the editorial board of JMM as well as the journal Microsystems and Nanoengineering.
Microelectromechanical system oscillators are devices that generate highly stable reference frequencies used to sequence electronic systems, manage data transfer, define radio frequencies, and measure elapsed time. The core technologies used in MEMS oscillators have been in development since the mid-1960s, but have only been sufficiently advanced for commercial applications since 2006. MEMS oscillators incorporate MEMS resonators, which are microelectromechanical structures that define stable frequencies. MEMS clock generators are MEMS timing devices with multiple outputs for systems that need more than a single reference frequency. MEMS oscillators are a valid alternative to older, more established quartz crystal oscillators, offering better resilience against vibration and mechanical shock, and reliability with respect to temperature variation.
