MICROELECTROMECHANICAL SYSTEMS Meaning and
Definition
-
Microelectromechanical systems (MEMS) are miniaturized devices that combine electrical and mechanical components to perform a wide range of functions. These systems are characterized by their microscopic size and are typically built using microfabrication techniques.
MEMS devices consist of tiny structures or systems that can sense and/or manipulate physical parameters, such as motion, pressure, temperature, or chemical composition. These structures are typically constructed using semiconductor manufacturing processes, allowing for precise control and integration of electrical and mechanical components on a chip.
Examples of MEMS devices include accelerometers, which measure acceleration or tilt, gyroscopes, which measure rotational motion, pressure sensors, which detect changes in pressure, and microvalves, which control the flow of liquids or gases. MEMS devices also find applications in the medical field, such as sensors used in pacemakers or lab-on-a-chip devices used for diagnostics.
The small size and low power consumption of MEMS devices make them well-suited for a variety of applications, including consumer electronics, automotive systems, aerospace technology, and biomedical devices. They offer advantages such as high performance, low cost, and integration with existing electronic systems.
In summary, microelectromechanical systems (MEMS) refer to miniaturized devices that combine electrical and mechanical components to sense and manipulate physical parameters. These systems are built using microfabrication techniques and find applications in various industries due to their small size, low power consumption, and high performance.
Etymology of MICROELECTROMECHANICAL SYSTEMS
The etymology of the word "microelectromechanical systems" (MEMS) can be broken down as follows:
1. Micro-: It is a prefix derived from the Greek word "mikros", meaning small or tiny. It generally denotes something on a small scale, usually measured in micrometers (µm) or millionths of a meter.
2. Electro-: This prefix is derived from the Greek word "ēlektron" which means amber. In modern usage, it refers to electricity or electronic systems.
3. Mechanical: This word is derived from the Latin word "mechanicus", meaning relating to machines or mechanics. It refers to the design, construction, and operation of machinery or mechanical systems.
4. Systems: It is derived from the Latin word "systema", meaning a whole composed of several parts that work together.
