MEMS Accelerometers
MEMS accelerometers, also known as micro-electromechanical system accelerometers, are utilized for measuring linear motion. These are sensor-manufactured devices that apply microelectronic fabrication techniques capable of producing microscopic-sized mechanical sensing structures on a silicon chip. Along with microelectronic circuits, MEMS accelerometers are used for calculating acceleration, shock, tilt, vibration, and other physical parameters. Read More
MEMS technology is ideal for building small integrated systems. These devices combine electrical and mechanical components and utilize IC (integrated circuit) batch processing techniques. Their size range is typically from micrometers to millimeters. Micro-electromechanical systems fabrication techniques combine accurate sensors with wireless communication - like Bluetooth and Wi-Fi – and powerful processing in one integrated circuit. The techniques make it possible for multiple devices to be created at the same time, thus resulting to scaled-up manufacturing and cost efficiency.
MEMS accelerometers use the principle of a proof mass that is suspended on a spring. The accelerometer is attached to an object and when this item accelerates, the mass creates a response as it intends to stay stationary due to inertia. As a result, the spring is compressed and stretched, thus building a force that correlates with its applied acceleration.
MEMS accelerometers benefit various applications across many industries, including the automotive, aviation, and consumer sectors. These smart wireless sensors are also used in low-power applications because of their advanced power saving features, which includes auto wake-up, a FIFO buffer for storing data, and low-power mode. Mobile phones and PDAs are some examples of handheld devices that benefit from MEMS accelerometers.
Types
There are two types of MEMS accelerometers: piezoresistive and capacitive.
- Piezoresistive accelerometers exhibit low sensitivity, which makes them ideal for shock and blast applications. These are higher range accelerometers as well.
- Capacitive accelerometers are lower range, low-cost devices. They have high sensitivity and are therefore beneficial for constant acceleration measurements and structural monitoring.
