A single turn 10K potentiometer is used in combination with the bite force sensor to create an adjustable voltage divider. This will probably be replaced with a fixed value resistor eventually, but it was helpful to have an adjustable value during testing. Here you can see the potentiometer zip tied to the back of the Teensy 3.1.
