MEMSkapacitiva

MEMSkapacitiva refers to a type of sensor technology that utilizes microelectromechanical systems (MEMS) to detect changes in capacitance. Capacitance is the ability of an object to store an electrical charge, and in MEMSkapacitiva sensors, this property is exploited to measure physical phenomena.

The core principle involves a movable element, often a diaphragm or a plate, that forms one part of a capacitor. When a physical stimulus, such as pressure, acceleration, or proximity, causes this element to move or deform, the distance between the capacitor plates changes. This change in distance directly alters the capacitance value, which can then be measured and translated into a meaningful electrical signal.

MEMSkapacitiva sensors are widely used in various applications due to their small size, low power consumption, and high sensitivity. They are found in pressure sensors for automotive systems, consumer electronics like smartphones (for touch detection and orientation sensing), and medical devices. Their ability to operate without direct contact in some configurations also makes them suitable for proximity sensing and non-contact measurements. The fabrication process for these sensors leverages standard semiconductor manufacturing techniques, allowing for cost-effective mass production.
