In Part 1 of this article, we explained popular liquid-level sensing methods and their limitations. We also delved into why capacitive-sensing techniques are superior to traditional methods used for ...

The DS-2100 and the DS-2100 WiFi displays from Loadstar Sensors Inc. are load indicators designed to work seamlessly with the company's patented capacitive load sensors. The DS-2100 and the DS-2100 ...

Capacitive sensors work by using the human body as one of the capacitive plates of an electrical circuit. A leader in low power capacitance touch sensors, NXP offers a range of auto calibrating ...

One of the main strengths of capacitive tactile sensing technology is its ability to help people access information that would otherwise be impossible to capture. Consider, for example, a ...

There are generally two types of accelerometers currently available—capacitor-based and thermal versions—and both are microelectromechanical devices (MEMS). So what’s the difference between the two?

As part of ongoing acoustic research scientists have created a workable sensor with the least possible resistance to motion. As part of ongoing acoustic research at Binghamton University, State ...

From Disney World to the smartphone in your pocket, fingerprint scanners have become commonplace these days. Even budget phones sport the tech, sometimes alongside other biometric unlocking options ...

Schematic representation of the laser speckle exposure system, comprising the UV laser, shutter, beam expander, mirror, convex lens, engineering diffuser, and wafer coated with photoresist. SEM images ...

Like most (if not all) Hackaday readers, I like to know how the technology I use works. I’m always amazed, for example, how many otherwise smart people have no idea how the cellphone network works ...
