Touch sensors have been around for years, but recent advances in mixed signal programmable devices are making capacitance-based touch sensors a practical and value-added alternative to mechanical ...

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 ...

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 ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

The big picture: Japan Display's Zinnsia technology marks a major leap toward more intuitive and ubiquitous human-computer interaction by transforming ordinary objects into smart, responsive surfaces.

Multi-frequency-region parallel sensing (MFRPS) is poised to enable larger-sized, thinner, and more responsive touchscreens.

Viable cell count (VCC), a critical parameter in both microbial and mammalian cell cultures, fluctuates during batch and fed-batch cultures. VCC is determined conventionally through sampling and ...
