1. A handheld controller comprising:
a controller body; and
a force sensing resistor (FSR) mounted within the controller body, the FSR comprising:
a first substrate made of polyimide and having conductive material disposed on a front surface of the first substrate;
a second substrate that is flexible and having resistive material disposed on a back surface of the second substrate, wherein the second substrate is disposed on the first substrate; and
one or more spacer layers interposed between the first substrate and the second substrate.
