MEMSteknologiaan

MEMSteknologiaan, often called MEMS technology, is a branch of engineering that deals with micro-electro-mechanical systems. It covers devices that combine tiny mechanical elements, sensors, actuators, and electronics on a common substrate, typically silicon, using microfabrication techniques developed for semiconductor manufacturing. MEMS devices include accelerometers, gyroscopes, pressure sensors, microphones, and microfluidic components, as well as miniature optical and RF elements.

Fabrication relies on microfabrication processes such as lithography, etching, deposition, and bonding. Methods include surface micromachining, bulk micromachining, and LIGA for high aspect ratio parts. Materials used in MEMSteknologiaan range from silicon and polysilicon to silicon carbide, polymers, and composite materials, enabling both rigid and flexible devices. The ability to integrate sensing and readout electronics on the same chip, often with CMOS circuitry, helps reduce size, power consumption, and cost.

Applications span consumer electronics, automotive systems, industrial monitoring, healthcare, and telecommunications. MEMS sensors are common in smartphones and wearables for motion detection, in vehicles for safety and control, and in industrial sensors for process monitoring. MEMS actuators enable precise microvalves, optical switches, and resonators, contributing to diverse systems from cameras to RF components.

Challenges include reliability and packaging, such as stiction, wear, thermal drift, and environmental protection, while allowing interaction with the surrounding medium. Ongoing research addresses materials compatibility, CMOS-MEMS integration, and advanced fabrication techniques to achieve higher performance, lower power, and greater integration. Overall, MEMSteknologiaan serves as a foundational technology that enables compact, mass-producible devices with integrated sensing and actuation capabilities.
