Claim 10:
11. The force sensor of claim 9, wherein:
the force sensor further includes a first input signal tap line, a first input signal tap point, a second input signal tap line, and a second input signal tap point;
the first compression strain gauge resistor, the first tension strain gauge resistor, the third compression strain gauge resistor, and the third tension strain gauge resistor are electrically coupled to receive a first input signal via the first input signal tap line;
resistances of the first input signal tap line are matched between the first input signal tap point and a junction of the first compression strain gauge resistor and the first tension strain gauge resistor and between the first input signal tap point and a junction of the third compression strain gauge resistor and the third tension strain gauge resistor;
the second compression strain gauge resistor, the second tension strain gauge resistor, the fourth compression strain gauge resistor, and the fourth tension strain gauge resistor are electrically coupled to receive a second input signal via the second input signal tap line; and
resistances of the second input signal tap line are matched between the second input signal tap point and a junction of the first compression strain gauge resistor and the first tension strain gauge resistor and between the second input signal tap point and a junction of the third compression strain gauge resistor and the third tension strain gauge resistor.
