1. An electronic device comprising:

  • a substrate comprising;

    a top surface; and

    a bottom surface;

    a first resistive sensor coupled to the top surface and formed from a material with a strain-sensitive electrical property;

    a second resistive sensor coupled to the bottom surface, positioned opposite the first resistive sensor and aligned with the first resistive sensor, and formed from a material sharing a thermal property with the material of the first resistive sensor;

    an integrated circuit comprising;

    a first digitally variable resistor; and

    a second digitally variable resistor positioned adjacent to the first digitally variable resistor within the integrated circuit;

    an addressing controller to couple the first resistive sensor, second resistive sensor, the first digitally variable resistor, and the second digitally variable resistor into a balancing network configuration; and

    a calibration controller to balance the balancing network.
