When the micro or nanostructure of a surface needs to be measured, an atomic force microscope (AFM) is frequently used. The sharp-tipped silicon AFM can measure the magnetic structure of a surface if it magnetized creating a magnetic force microscope (MFM). For improved measurement capability, NT-MDT uses a thinner coating of the magnetic layer in its […]

Tracking Motion in Portable Products -3
The large and rapidly growing smartphone, tablet, and health and fitness devices market can take advantage of advanced motion sensing technology. At the 2013 International CES, several companies announced new products to address these applications. With proprietary calibration and sensor fusion algorithms, Kionix KMX61G is a 6-axis device can provide 9-axis accelerometer, magnetometer (e-compass) and […]
Tracking Motion in Portable Products -2
Augmented reality (AR), more immersive gaming, personal health and fitness, indoor navigation and other appliances requiring context awareness can take advantage of advanced motion sensing technology. At the 2013 International CES, several companies announced new products to address these applications. Bosch Sensortec describes its BNO055 as the first in a family of Application Specific Sensor […]
Tracking Motion in Portable Products -1
Mobile devices, wearable sensors, fitness watches and remote health monitoring appliances are among the products that can take advantage of advanced motion sensing technology. At the 2013 International CES, several companies announced new products to address these applications. InvenSense MPU-9250, in a 3x3x1mm QFN package, is a fully-integrated 9-axis device that includes a gyroscope, accelerometer […]
Rotary Position Sensor Adds Mating Connector
Packaging provides a critical success factor for just about any product including sensors. Recognizing that some potential customers would prefer a connector rather than a surface mounted package, Piher designed a printed circuit board (PCB) to mount both its MTS-360 Rotary Position Sensor and a couple of mating connector options. The MTS-360PCB Rotary Position Sensor […]
Sense Torque – Save Fuel and More
Carmakers investigate and implement many technologies to save fuel. Rather than have a hydraulic, belt-driven power steering system, electronic power steering systems with a torque sensor measure the resistance and provided the appropriate amount of assistance and save fuel – as much as 5% reduced fuel consumption. Based on Hall Effect technology, TT electronics SX-4428 […]
Partnering for Motion Sensing in Wearable Products
Market analyst ABI Research predicts that over the next five years, the total market for wearable wireless devices in sports and healthcare will grow to 169.5 million devices in 2017, up from 20.77 million in 2011. Showing that they expect to get their fair share of this growth, 3D motion tracking experts Xsens and leading […]
Coordinating the Sensing in Portable Tablets/Smartphones
Portable tablets and smartphones contain several sensors that detect motion, including an accelerometer, RGB light, digital compass or magnetometer, proximity, gyroscope and barometer. Many of these sensors make multi-axis measurements. The data are used for a wide range of applications including gaming, navigation and virtual reality. For its recently launched Galaxy Note II, Samsung selected […]
ASM presents a compact magnetic angle sensor
ASM presents the PRDS1, a compact magnetic angle sensor in M12 housing and sets new standards. The angle is measured without contact and wear-free over the entire measuring range up to 360° via a separate magnet. From the POSIROT® family of magnetic angle sensors ASM presents an especially compact sensor. Only 12 mm in diameter […]
Avoid Problems in Magnetic Sensor Layouts
In this Frank Talk About Sensors, Michael Stanley and Talat Ozyagcilar from Freescale Semiconductor explain a new tool developed by Freescale to Sensor Tips’ Senior Editor Randy Frank. Provided as a service to customers designing in magnetic sensors into their applications, the tool helps avoid layout problems that can affect a magnetic sensor’s output.
