Scientists have developed a sensor for measuring the strength of electric fields, which is much smaller, simpler and less prone to distortion than comparable devices. TU Wien has developed a sensor ...

Sensors play a large role in gathering information in a multitude of automotive and aerospace test setups. Brett Burger, an engineer at National Instruments specializing in aerospace applications, ...

Measuring RF Power Sensor Nonlinearity RF power sensor linearity is a commonly misunderstood topic. To obtain the most accurate power measurements, though, you need to understand what linearity is, ...

In February, six students on snowshoes battled as much as 12 feet of snow to penetrate into the heart of the American River basin. Moving through dense forests and meadows, they mounted 90 iPhone-size ...

Fig 1. The MEMS pressure sensor detects the tensile stress on a thin silicon membrane that changes the piezo-resistance of elements on the membrane’s surface. Fig 2. The MEMS sensor’s piezo-resistive ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
