They project sense fields through almost any dielectric, like glass, plastic, stone, ceramic, and wood.
They can also turn small metal-bearing objects into intrinsic sensors, making them respond to proximity or touch.
This capability coupled with an ability to self-calibrate continuously leads to entirely new product concepts.
These devices are designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywhere a mechanical switch or button may be found; they may also be used for some material sensing and control applications provided that the presence duration of objects does not exceed the recalibration timeout interval.
A piezo element can also be connected to create a feedback click sound.
These ICs require only a common inexpensive capacitor in order to function.
Average power consumption is under 20µA in most applications, allowing battery operation.
The devices employ digital signal processing...
