Microelectromechanical systems (MEMS) electrothermal actuators are widely used in applications ranging from micro-optics and ...

Precision alignment in semiconductor lithography demands nanometer-scale accuracy, as even minor misalignments between the mask and wafer can drastically impact chip yield. However, existing optical ...

Achieving both high sensitivity and a wide dynamic range remains a central challenge in microelectromechanical accelerometers.

Researchers in Drexel University’s College of Engineering have developed a solar-powered, wireless sensor system that can continually monitor bridge deformation and could be used to alert authorities ...

When the job at hand is measuring something with micron-range precision, thoughts generally turn to a tool with a Mitutoyo or Starrett nameplate. But with a clever design and a little electronics know ...

Inductive eddy current position/displacement sensors require an electrically conductive target. The target does not have to be grounded, and in general, the more electrically conductive it is, the ...

This circuit provides different ways to measure the current-voltage phase displacement of a line-powered ac load. The classic approach for sensing an ac load's current requires a transformer or ...

Linearity is better than 0.01% and repeatability is 0.005%. Position update rate is 1.5 kHz. The sensor does not require recalibration after installation. Each sensor ...

Accelerometers turn motion into measurable signals. From tilt and vibration to g-forces, they underpin countless designs. In this “Fun with Fundamentals” entry, we demystify their operation and take a ...
