Accelerometer provides low power for healthcare and industrial applications

Analog Devices has announced a three-axis MEMS accelerometer designed for a wide range of healthcare and industrial applications, including vital signs monitoring, hearing aids, and motion-enabled metering devices.

The ADXL367 accelerometer improves power consumption by two times versus a previous generation of the device (ADXL362) while improving noise performance by up to over 30 percent. The new accelerometer also provides extended field time that maximises battery life and reduces maintenance frequency and cost.

The ADXL367 consumes only 0.88µA at a 100Hz output data rate and 180nA when in motion-triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL367 does not alias input signals by undersampling but rather samples the full bandwidth of the sensor at all data rates.
