What is a micro-electro-mechanical system (MEMS) and its applications?
1 Answer
A micro-electro-mechanical system (MEMS) is a miniaturized device or system that combines electrical and mechanical components on a small scale, typically in the micrometer to millimeter range. MEMS technology leverages microfabrication techniques used in the semiconductor industry to create these tiny devices with diverse functionalities. MEMS devices often consist of miniature sensors, actuators, and electronic circuits integrated onto a single chip.
Applications of MEMS span across various industries and fields due to their small size, low power consumption, and ability to interact with the surrounding environment. Some common applications of MEMS include:
