MEMS inclinometers are miniature devices designed to measure the angle of inclination or tilt of an object relative to gravity. MEMS stands for Micro-Electro-Mechanical Systems, indicating that these sensors are fabricated using microfabrication techniques similar to those used for integrated circuits. This allows for the creation of very small, lightweight, and low-power inclinometers.

The core principle behind MEMS inclinometers typically involves a proof mass suspended by tiny springs. When the sensor is tilted, gravity acts on the proof mass, causing it to move. This displacement is then detected and converted into an electrical signal. Various sensing technologies can be employed, including capacitive, piezoresistive, or resonant sensing. Capacitive sensors measure the change in capacitance between the proof mass and fixed electrodes as their relative position changes due to tilt. Piezoresistive sensors utilize materials whose electrical resistance changes with applied mechanical stress, which occurs when the proof mass deforms the sensor structure. Resonant sensors exploit changes in the resonant frequency of oscillating structures.

MEMS inclinometers offer several advantages over traditional inclinometers, such as their small size, low cost, high reliability due to fewer moving parts, and ability to be integrated into complex systems. They are widely used in a variety of applications including mobile devices for screen orientation sensing, automotive systems for stability control and navigation, industrial automation for precise positioning, robotics for balance and movement control, and aerospace for attitude determination. The accuracy and range of MEMS inclinometers can vary depending on the specific design and sensing technology used.
