555 Timer Delay on Trigger
What you describe can be done with a 555, or two logic gates, or two transistors, but your question is missing some details.
What is the part number or website for the sensor?
What is the circuit ...

Time delay circuit to reverse the rotation of DC motor when input is high
Just use a cheap micro for the control. You'll need an h-bridge for the motor control if you want to reverse the direction.
If you really want a discreet IC design then a 555 timer one shot should ...

Why does the air gap between the electrode and the overlay of a capacitive sensor have a negative impact on the touch performance?
The problem is that air gaps not only influence the base capacitance, they also influence the capacitance of the touch sensor when someone actually touches it.
The air gap essentially acts like ...
