How are ultrasonic MEMS sensors being used for 3D obstacle detection and collision avoidance?

April 4, 2022 By RFrank

In addition to radar, LiDAR and camera sensing used in 3D obstacle detection and collision avoidance in advanced driver assistance systems (ADAS) in vehicles, ultrasonic sensing has been used as well. Traditionally, the ultrasonic sensors used transducer-based technology to provide a microphone to transmit and receive the ultrasonic signal in passenger vehicle parking applications. Using Infineon’s […]

PIGAs can indeed fly – and are still the best, Part 1: Frame of reference

March 30, 2022 By Bill Schweber

The PIGA is the oldest accelerometer, is widely used in rocketry and guidance, and is still the best – but MEMS-based devices are getting closer. When you see an inexpensive drone, a more sophisticated one, an unmanned aircraft, a standard piloted aircraft, guided or intercontinental ballistic missile ICBM), an underwater drone or submarine, or a […]

How can a MEMS microphone be used in harsh environments?

February 21, 2022 By RFrank

The answer depends on how harsh of an environment and how much protection is required. For a microelectromechanical systems (MEMS) microphone, one of the most-harsh environments is the human body, since sweat and dirt can cause failures in traditional MEMS microphone architectures. Regarding the protection, the International Electrochemical Commission’s (IEC’s) IEC 60529 rating system defines different […]

Nuances of low power MCUs for wireless sensors and wearables

October 22, 2021 By Jeff Shepard

The optimization of microcontrollers (MCUs) in power-sensitive applications such as wireless sensor nodes and wearables is all about maximizing power management effectiveness. To minimize power consumption, low-power MCUs typically operate at frequencies below 50 MHz, compared with hundreds of MHz or even 1+ GHz for conventional MCUs. These power-optimized MCUs also use low-power peripherals; they […]
