Thanks you for the guide. I'm trying to control a 12V actuator with the sensor. I'm stepping voltage down to 5V (see link 1) to the sensor. Then from the sensor to a step up convertor (see link 2) back to 12V. The step up convertor can't go above 6.04 V. Do I need to add anything to the I/O of the sensor so that the step up convertor can reach the target 12V? Thank you.

If I'm understanding what you're trying to do correctly I'm afraid you can't power the step-up power supply module from the output of the touch sensor. The TTP223's output is just a digital pin and is only capable of sourcing a maximum of 8mA which I doubt is enough to power both the step-up module and the actuator. I would suggest using the sensor to switch a transistor or a relay module like below which you could then use to switch power to your step-up module:
