IndustryMEMS-240x160The ADXL362, from Analog Devices, is a 3-axis, digital MEMS accelerometer operating at 300 nA in motion sensing wake-up mode, an estimated 60% less current consumption than the closest competing sensor in the same mode. In full measurement mode, the ADXL362 uses 2 μA at a 100 Hz data rate, estimated to be 80% less power consumption than competing devices, the company says. This low power consumption allows the device to be used in applications that require battery life expectancy of months or years, and where battery replacement can be impractical or dangerous to the equipment or operator. The accelerometer can be used as part of an intelligent, continuously operational, motion-activated switch. The accelerometer is planned for implementation into the second generation of DARPA's Blast Gauge, which serves as both a screening tool for medical personnel performing triage on individuals exposed to a blast and provides detailed data for the research community unlocking the causes of Traumatic Brain Injury. Samples of the ADXL362 MEMS accelerometer are available now with full production projected for August 2012. Pricing is $3.97 each/1,000.
