Colibrys (Switzerland) Ltd. has announced today the release of its new MS9005, a ±5g range MEMS accelerometer, to complement its existing family of +/-2g and +/-10g products targeted primarily at AHRS applications.
Current and future developers of AHRS using Colibrys accelerometers will benefit from this new product as an alternative to existing selection of products, which are the traditional Colibrys-MS9002 and MS9010 sensors dedicated to standard AHRS and the latest world's best open-loop RS9010 accelerometer dedicated to mid range requirements.
According to Jean-Michel Stauffer, VP Sales & Marketing at Colibrys, "the MS9005 offers optimal accelerometer performance for applications that operate in medium level vibration and shock environment but where absolute bias and scale factor stability and reduced VRE (Vibration Rectification Error) are valued. Typical examples of AHRS integrating Colibrys accelerometers are airplanes, helicopters and UAV as well as backup systems on large aircrafts and small jets. This new product strengthens Colibrys' position as the world leading supplier of MEMS accelerometers for AHRS applications"
This product benefits from the specialised knowledge and applications experience of Colibrys accelerometers in term of reliability for harsh environments and safety critical applications.

STMicroelectronics (NYSE: STM), the leading supplier of MEMS for consumer and portable applications[1], has introduced the first members in its iNEMOTMfamily of multi-sensor Inertial Measurement Unit (IMU) devices. The integration of a variety of motion, magnetic, pressure and temperature sensors with a 32-bit processing unit and dedicated software in one package will lead to leaps in functionality and performance in a wide variety of applications, including Gaming, Human Machine Interface, Robotics, Portable Navigation Devices and Patient Monitoring.
The STEVAL-MKI062V1 (iNEMOTM) is a unique platform designed to demonstrate the performance of ST's most advanced inertial, temperature and pressure sensors. It provides a complete set of inertial measurements from an accelerometer, magnetometer and gyroscopes, as well as data from pressure and temperature sensors to measure environmental conditions.
This 10-DOF (degrees of freedom) inertial system represents a complete hardware platform for a variety of applications including virtual reality, augmented reality, platform stabilization, human machine interfaces and robotics.
The STEVAL-MKI062V2* is the second generation of the iNEMOTM module family. It combines accelerometers, gyroscopes and magnetometers with pressure and temperature sensors to provide 3-axis sensing of linear, angular and magnetic motion, complemented with temperature and barometer/altitude readings, representing the new ST 10-DOF (degrees of freedom) platform.
Based on the previous version, the STEVAL-MKI062V2 represents another step forward in miniaturization, integrating five ST sensors: a 2-axis roll-and-pitch gyroscope, a 1-axis yaw gyroscope, a 6-axis geomagnetic module, a pressure sensor and a temperature sensor.

The Bosch Sensortec inertial sensor SMI540 is a new compact component with high accuracy and reliability, especially designed for automotive Vehicle Dynamics Control systems. The sensor consists of two micro-machined sensor elements and a signal processing ASIC packaged together in a molded plastic housing for surface mounting. The concept of combining angular rate and acceleration sensors in one SOIC16w package aims to provide an efficient one-chip solution for VDC applications without compromising on quality and standard system performance.
Unpackaged Angular Rate Sensor from Bosch
Digital signal processing combined with closed loop operation of the angular rate sensor and digital output via SPI (Serial Peripheral Interface) guarantees excellent durability with respect to mechanical and electrical interference. The sensor continuously perform internal selftests and parametric monitoring of the sensing elements and the ASIC during operation. In combination with a multitude of customer specific signal monitoring options, the sensor is particularly suitable for safety critical applications.

SensorDynamics, a producer of sensors for the automotive and manufacturing industries, today launched four new MEMS gyroscopes: SD705 to SD708 in a tiny QFN40 package. The sensors are characterized by low cross sensitivity to shock and vibration; and provide a stable rate signal in the short as well as the long time range due to their good noise performance. This makes them well suited for ambitious measurement and control applications such as mobile satellite tracking or yaw control of model helicopters. In addition, the sensors feature continuously working self-diagnosis functions without the need to interrupt measurement data acquisition.
APPLICATIONS
- Navigational systems
- Platform stabilization
- High end toys (e.g. helicopters)
- Image stabilization
- Motion control
The four gyroscopes in the SD70x line differ with respect to their supply voltage, which is either 3.3 V or 5 V, and regarding the direction of their sensitive axis, which is either in the sensor's assembly plane (X-gyro) or perpendicular to it (Z-gyro). All sensors have a SPI interface and simultaneously provide two calibrated measurement ranges of ±100°/s and ±300°/s. As a special advantage for control applications the rate signals of both measurement ranges does not saturate until ±128°/s and ±512°/s, respectively; hence fast movements that exceed the measurement range can still be captured. The gyroscopes can easily be adapted to the customer's application since they are calibrated over the whole operating temperature range of -40°C to +85°C to a maximum error of ±5°/s and need only a few external components to operate. More details are to be found in the SD70x data sheet

Technological Leap for MEMS Sensors:
Bosch Sensortec introduces the smallest
BMA220 g-sensor in LGA housing to the global
market
Triaxial digital sensor with dimensions of 2 x 2 mm
- First MEMS sensor with a 2 x 2 aspect ratio in an LGA housing
- 55% reduction in surface area over current 3 x 3 LGA housings
- Automatic recognition of specific movements
- No external microcontroller is required for signal analysis
The BMA220 digital sensor from Bosch Sensortec is the smallest digital acceleration sensor in LGA housing in the world ‒ it measures only mm x 2 mm x 0.98 mm, including LGA housing. For the second time, Bosch Sensortec, the Bosch subsidiary specializing in sensors for consumer electronics, has emerged as the pace setter for technological innovation: In 2007, Bosch Sensortec was the first to successfully pack sensors in LGA housings measuring only three millimeters ‒ until then, the standard had been four millimeters. However, the unbroken trend towards miniaturization in mobile consumer electronics demands an even greater reduction in surface area: The new generation of 2 x 2 LGA housings occupies 79% less surface area on a circuit board than that required for the 6 x 6 sensor that marked Bosch Sensortec's market debut in 2005.

ASM (Automation Sensorik Messtechnik GmbH, in Germany) introduces its smallest addition to the POSITILT® inclinometer series that is available in single and dual axis versions. By using MEMS technology, this new inclinometer PTAM20 series is packaged into a very compact, flat housing making it ideally suited for OEM applications.
The measurement range for the single axis version is available from +/- 15° to +/- 180°, in increments of 15°. For the dual axis version, the measurement range is available from +/- 15° to +/- 60°, in increments of 15°.Due to its small size of 7mm in height and 48 mm in diameter, the PTAM20 series inclinometer has been designed to fit into the tightest locations in OEM applications. The enclosure is rated IP60 which is suitable for many instrumentation functions.
The maximum measurement range for the single axis version is +/- 180° and +/- 60° for each axis in the dual axis version. Each version is available with smaller ranges in +/- 15° increments. Several analogue output types are available: 0.5-4.5 V, 0.5-10 V and 4-20 mA.
The resolution is 0.05° and the linearity is up to +/- 0.5°. Each version offers high shock resistance.
