Angular acceleration sensors have the ability to measure the rate of change of angular velocity with respect to time, making them ideal for use in vehicle control and monitoring systems. Murata, a Japanese company specializing in design, manufacture and sale of ceramic-based passive electronic components & solutions, has announced it's just developed the world's first surface mount MEMS angular acceleration sensor.
Though not available yet for order, the sensor will also be the world's smallest SMD-type angular acceleration sensor, measuring 5.2 x 2.5mm typ. x 0.8mm max. It features high sensitivity, low noise, and wide frequency band. It can be used to detect rotational vibration, making it useful in industrial uses as well as automotive systems.
The new angular acceleration sensor has a detection frequency band of more than 1kHz and an angular acceleration equivalent noise effective value of less than 1rad/s²ms.
