Acceleration Sensors Buying Guide

Acceleration sensors are ICs that measures vibration or shock for a variety of applications. An electric sensor is used to measure the accelerative forces for determining and monitoring an object’s movement and position.

Low-g and high-g accelerometer

A low-g accelerometer is used for detecting subtle motion, for example, in device orientation. A low-g accelerometer makes a perfect apparatus for most experiments held in schools and colleges, including Simple harmonic motion, Newton’s second law, and determining the relation between force and acceleration. A high-g accelerometer, on the other hand, is more precise for measuring shock detection, concussion detection, and impact recognition. A novel piezoresistive high-g accelerometer design offers a wide range of bandwidth without sacrificing its sensitivity.

Piezoelectric acceleration sensors

A piezoelectric accelerometer works on the principle of the piezoelectric effect to sense the change in acceleration. They are most commonly used in shock and vibration measurement. These sensors offer a wide range of frequency that ranges from a few hertz to 30 kHz. They are available in various sensitivity, weights, shapes, and sizes. Most of the piezoelectric sensors exist with a charge amplifier integrated with the sensor casing that converts the output into voltage.

Piezoresistive acceleration sensors

Piezoresistive acceleration sensors are much less sensitive than piezoelectric sensors. They are suitable for automobiles, such as vehicle crash testing. Piezoresistive accelerometers are not suitable for vibration measurement and are mainly employed for shock measurement. However, they offer a wide range of higher bandwidth, varying from a few hundred hertz to 130 kHz. For measuring long-duration transient, the frequency response often goes down to 0Hz or steady-state.

Capacitive accelerometers

A variable capacitive accelerometer is the most common type of accelerometer available in the market. They use a change in electric capacitance to detect an object’s acceleration. These sensors are manufactured using MEMS technology, which is suitable for measuring low-frequency vibration, motion, and steady-state acceleration. Thus, they are widely used in airbags and handy devices like mobile phones. A capacitive accelerometer is highly sensitive with a narrow bandwidth that ranges from 15hz to 3000Hz; besides, they show exceptional temperature stability.
