AMR Sensor with 3D Sensing Capabilities - Another World's First, from Murata

Murata Manufacturing Co., Ltd. (TOKYO:6981) (ISIN:JP3914400001) (hereinafter "Murata") has developed the world’s first AMR sensor with 3D sensing capabilities supporting 360-degree magnetic field detection with uniform sensitivity in all directions. Magnetic field detection in three-dimensional space previously required the use of multiple magnetic sensors in combination, but the new sensor makes 3D magnetic field detection possible using a single device.

An anisotropic magneto-resistance (AMR) sensor is a type of magnetic sensor that utilizes a property such that the magnetic resistance value changes according to the strength of a magnetic field in a specific direction. These kinds of sensors are mainly used in applications such as mobile phones and notebook PCs, open/close detection in refrigerators and doors, and rotation detection in smart meters.
In response to feedback from customers indicating a need for AMR sensors with 3D sensing capabilities, Murata embarked in 2013 on the development of such devices, utilizing magnetic sensing technology and expertise acquired from NEC Corporation. By combining AMR element design technology and circuit design technology from NEC and Murata, this effort has resulted in the successful development of a sensor capable of 360-degree magnetic field detection with uniform sensitivity in all directions. Previous magnetic sensors had directional sensitivity characteristics that made them unsuitable for omnidirectional magnetic field detection, requiring three to six sensors for 3D sensing applications. The new sensor makes it possible to accomplish detection with a single device, thereby enabling customers to design products that are more compact and lower in cost.

1. Capable of omnidirectional magnetic field detection over 360 degrees in parallel with the chip surface.

2. Compact Package
The compact package measuring only 1.45 × 1.45 × 0.55 mm is achieved by using a single element for omnidirectional detection.

• Magnetic tampering detection in power, gas, and water meters; security devices; game machines
• Mobile phone proximity switching in hearing aids

DevOps theory promotes a culture of continuous improvement built on collaboration, empowerment, systems thinking, and feedback loops. But how do you collaborate effectively across the traditional silos? How can you make decisions without system-wide visibility? How can you see the whole system when it is spread across teams and locations? How do you close feedback loops across teams and activities delivering complex multi-tier, cloud, container, serverless, and/or API-based services?
Today every business relies on software to drive the innovation necessary for a competitive edge in the Application Economy. This is why collaboration between development and operations, or DevOps, has become IT’s number one priority. Whether you are in Dev or Ops, understanding how to implement a DevOps strategy can deliver faster development cycles, improved software quality, reduced deployment times and overall better experiences for your customers.
