The success of the capacitive sensor scroll wheel used in devices such as the iPod has caused other consumer product development teams to evaluate capacitive sensors to enhance the user interface and ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

Many people mistake the growth in capacitive touch sensors as the adoption of new technology. But the fact is advances in mixed-signal programmable devices, those that combine analog and digital into ...

Apple is examining a shift from a force sensor in AirPods to a capacitive touch system to make a set easier to control, and provide new options. The latest in Apple's surprisingly long history of ...

With the introduction of the first smartphones in 2012 with in-cell touch displays, a battle is emerging between the traditional supply chain of ITO-based touch sensors that are externally combined ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

The sensors provide a reliable alternative to mechanical switches that may have a high rate of wear and tear. The sensors use capacitive technology for start and stop actuation, and are available with ...

• 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 ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

Capacitive touch buttons are a great way to turn just about any (non-conductive) surface into a button, but people generally dislike the lack of tactile feedback. [KontinuumLab] apparently agreed and ...
