Help-sensor problem

The current situation is that I want to use a lot of small sensors to make a 1.5m sensor strip/rod for positioning. A certain position of the sensor bar is touched by a human hand, and a signal (analog or digital) that can identify the position is transmitted, or the information of the touched position is detected by passive refreshing, with an accuracy of about 5~10mm.

I’m not very familiar with sensors, so I’d like to ask.

  1. What kind of sensor should be used? (Considering the cost, the pressure sensor may be more suitable, but I don’t know what kind of sensor to use)
  2. With so many sensors side by side, what kind of signal detection method should be used?
