I would like to work on a science project which I will measure people how much pressure I have to put on a pressure point to start to hurt somebody. Is there a device which I can measure the pressure that I apply onto the person's skin? Thank you!

    $\begingroup$ We need more information. Pointed object like a needle or pencil VS s flat surface has a strong relationship to pain. $\endgroup$ Sep 12 '17 at 20:34

Use a load cell or a digital scale to measure force. A lower accuracy force-sensing resistor may be sufficient. If you simplify your test to vertical, gravitation force on a known mass may suffice.

As user8055 pointed out, you will need to make sure the area and shape of the end of the protrusion is constant in your testing.

  • $\begingroup$ This answer may mislead the OP. Pain comes from a variety of insults - thermal mismatch, gross pressure, skin penetration, etc. Duration of force -- slow application vs. impulse -- matters as well. $\endgroup$ Sep 13 '17 at 15:27
  • $\begingroup$ @Carl Witthoft, Good point. There are probably much more controllable experiments that could be chosen. I just gave some force measurement options. Everything else would have to be held constant. $\endgroup$
