Abstract
A resistive force sensing circuit and a resistive force sensing apparatus. The circuit includes a plurality of sensor circuit inputs, a plurality of sensor circuit outputs; and a plurality of resistor units. Each of the resistor units includes a force-sensing resistor, a first side resistor, and a second side resistor. The first terminals of the force-sensing resistor, the first side resistor and the second side resistor are electrically connected to each other at one node, a second terminal of the force-sensing resistor is electrically connected to one of the sensor circuit inputs, and second terminals of the first side resistor and the second side resistor are electrically connected to two adjacent sensor circuit outputs, respectively. The first side resistor and the second side resistor are a pair of resistors with substantially equal resistance. The apparatus includes structures to realize the function of the resistive force sensing circuit.
