The Mars Environmental Dynamics Analyzer (MEDA) on the Perseverance rover is characterizing the surface weather as well as the dust particle size and morphology. Understanding dust behavior is a key to predicting Martian weather. Dust influences Mars’ weather the way that water controls Earth’s weather. Two of MEDA’s weather-related goals are: determination of the destructive […]

Keysight’s Innovation Challenge is back for 2022
The student competition for IoT designs to mitigate climate change and reduce energy consumption is back on track for 2022. Registration opens April 4. After a two-year COVID-19 hiatus, Keysight Technologies has rebooted its IoT Innovation Challenge. The Keysight Innovation Challenge 2022 student competition challenges students to design IoT devices that sense our world and […]
How are ultrasonic MEMS sensors being used for 3D obstacle detection and collision avoidance?
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 3: History and future
The PIGA is the oldest accelerometer and widely used in rocketry and guidance, and still the best – but MEMS-based devices are getting closer. The previous parts looked at the principle and operation of the PIGA. This part looks briefly at its history and refinement and the MEMS-based versions of the PIGA being developed and […]
PIGAs can indeed fly – and are still the best, Part 2: Operation
The PIGA is the oldest accelerometer and widely used in rocketry and guidance, and still the best – but MEMS-based devices are getting closer At the core of each single-axis PIGA is a gyroscope. The performance of this gyro – which is unrelated to the orientation gyros – plays a large role in determining the […]
PIGAs can indeed fly – and are still the best, Part 1: Frame of reference
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 […]
What’s happening in medtech/wearables sensor applications?
According to Markets and Markets, the global wearable technology market is projected to grow from $115-120 B in 2021 to $260-265B in 2026 with a compound annual growth rate (CAGR) of 18-20%. Sensors represent a key enabling technology in wearables. Mordor Intelligence identified examples of sensors in wearable products that include Apple Watch’s EKG capabilities […]
Streaming 4x cameras with small carrier board: fast prototype
Embedded vision components are ever-popular and are being incorporated into a plethora of applications. What all these applications have in common is the need to pack more functionality into tight spaces. Often, it is advantageous for these systems to make decisions on the edge. To enable such systems, including the ability to prototype quickly, Teledyne […]
