Two conductive plates are required, one connected to the sensor port and the other one to the circuit ground to form a capacitive transducer. So the ground plane is not just like a shield in the ...

These electrodes add no material cost to the system, because they’re incorporated into the same circuit-board layout as the touch sensors (Fig ... the top view of the PCB for this application.

The input impedance of the trigger is very high and the touch sensor switch can be triggered by the voltage induced in the human body. The relay is a 12 V DC relay operating at currents less than 200 ...

Fox has created a custom PCB he calls Spoke that turns all 26 pins on the Pico into an individual touch sensor. According to Fox, the idea began when he first realized that he could use a 1M ...

A simple four-component circuit allows a single I/O line from any microcontroller to sense the states of two capacitive touch sensors ... in-Chief of Machine Design until 2014.

Digital circuit design guidelines. Differences in the guidelines between the two. Several products in the electronics industry require both analog and digital printed-circuit-board (PCB ...
