Definition
Microelectromechanical systems (MEMS) are micron-size devices that can sense or manipulate the physical world.
MEMS are made up of components between 10 to 100 micrometers in size (i.e. 0.01 to 0.1 mm) and MEMS devices generally range in size from a 20 micrometers (20 millionth of a meter) to a millimeter (thousandth of a meter).
History of MEMS
The invention of the transistor at Bell Telephone Laboratories in 1947 sparked the fast-growing microelectronic technology industry.
Jack Kilby of Texas Instruments built the first integrated circuit (IC) in 1958 using germanium (Ge) devices.
The first high-volume pressure sensor was marketed by National Semiconductor in 1974 - it included a temperature controller for constant-temperature operation.
Around 1982, the term micromachining came into use to designate the fabrication of moving micromechanical parts.
Components of MEMS
MEMS can include two or more
of the following subsystems: sensors, actuators, a power supply, a central processing unit (CPU)
or microprocessor, and/or a communication interface.
Medical Applications
Disposable Blood Pressure Sensors
MEMS transducer senses blood pressure through a silicon-based dielectric gel between the sensor and the saline solution.
Drug delivery
MEMS devices can be positioned in the body by implantation or by the traditional pill.
MEMS in Defense
Cyborg insects with MEMS that will run remotely controlled reconnaissance missions for the military. MEMS sensors, such as video cameras, audio microphones, and chemical sniffers so that they could move into enemy territory in swarms to perform reconnaissance missions otherwise dangerous for soldiers.
Smart dust: A tiny wireless sensors (MEMS), robots and devices, installed with wireless communications, that can detect anything from light and temperature to vibrations.
