Low-SWaP accelerometer replaces quartz sensors
The Tronics AXO315®T1 from TDK Corporation is a single-axis, closed-loop MEMS accelerometer for measurement while drilling and related downhole navigation tasks, with a ±14 g input range and an operating temperature range of -30°C to +175°C. Designed for high vibration and high-temperature drilling environments, it provides a 24-bit digital SPI interface, specified vibration rectification error […]
MEMS Sensors Help Detect Equine Lameness
Thanks to a University of Missouri professor of equine surgery in the College of Veterinary Medicine, a commercially available product can detect horse lameness. Inputs from MEMS accelerometers and a gyroscope are transmitted by a Bluetooth® wireless transceiver (within 150 yards) to a motion computing tablet PC. Accelerometers are mounted the horse’ head and pelvis and […]
Robot Provides Virtual Presence at 2012 CES (Pt 2)
At the 2012 International CES (Consumer Electronics Show) in Las Vegas, Alexandra Dopplinger, a marketing manager at Freescale Semiconductor explains the capability of a remote robot that she controls from her location in Ottawa, Canada. Freescale’s pressure sensors and accelerometers are used in the design of the robot as well as proximity sensors to detect […]
Nine-Axis Sensing Enables Games and Augmented Reality
At the 2012 International CES (Consumer Electronics Show) in Las Vegas, Frank Melzer, CEO of Bosch Sensortec demonstrates 9-axis sensing using a combined accelerometer and eCompass magnetometer with the company’s newest 3×3-mm triaxial gyroscope, the BMG160. The 9-degree of freedom sensing combined with an imaging system and additional software enables augmented reality. In addition, Melzer […]
To Your Health: 3-Axis Accelerometers and Gyroscopes Provide Feedback
At the 2012 International CES (Consumer Electronics Show) in Las Vegas, Eric Zorich, CEO of Diesel Dogs describes how a three-axis accelerometer and three-axis gyroscope are used to provide a set of Smart Weights. The software in the design allows users to properly exercise and obtain the maximum benefit from a workout. The concept placed […]

Accelerometer Helps Archers Hit the Mark
When new products are introduced, manufacturers like to identify other potential applications beyond the one used to drive product development. Mounting an accelerometer on an arrow tip to provide ballistic measurements to evaluate bows probably was not on any accelerometer manufacturer’s list. However, that is what Full Flight Technology does to improve high-performance archery. Using […]
Smallest Sensor Week: Dual-Axis Digital Accelerometer Boasts Smallest Packaging
The second of this week’s small sensors is the world’s smallest and most robust digital accelerometer from MEMSIC Inc. Using patented MEMS thermal technology manufactured with a standard 0.18 µm CMOS process and advanced wafer- level packaging (WLP), the MXC6226XC two-axis digital accelerometer fits within a 1.2. x 1.7 x 1.0 mm package. Per the company’s […]
Sense Acceleration with a 2 x 2-mm Package
Sensing acceleration in a space-constrained end product may result in the tradeoff of another feature if the accelerometer takes too much space. To avoid the conflict, STMicroelectronics introduced three-axis accelerometers in 2×2 mm packages. The tiny sensors have a quite a few features of their own. With full-scale ranges of ±2g/±4g/±8g/±16g, the LIS2DH and LIS2DM […]
