Paragrafo 1: Microelectromechanical systems (MEMS) are miniature devices that combine mechanical elements with electrical components. They are developed using electronic manufacturing technology, which allows for miniaturization and low-cost production. Examples of MEMS operations in everyday life include airbag release sensors in cars, motion and orientation detection in smartphones, and blood pressure measurement in medical equipment. MEMS components are between 1 and 100 micrometers in size.

Domanda: What are some examples of MEMS operations in everyday life? A) Airbag release sensors in cars B) Motion and orientation detection in smartphones C) Blood pressure measurement in medical equipment D) All of the above

Risposta corretta: D) All of the above

Paragrafo 2: A new generation of even smaller components called NEMS is approaching. NEMS have dimensions of the order of nanometers, making them extremely flexible and suitable for a wide range of applications. MEMS devices can vary from simple structures with no moving elements to complex electromechanical systems with multiple moving parts. Their two key functions are as sensors and actuators. MEMS sensors can detect environmental phenomena such as temperature, acceleration, pressure, chemical composition, magnetic fields, and radiation.
