Micro load cells use piezo-resistivity, where resistance changes with applied load, causing output voltage change. Multi-axis cells measure forces in multiple directions using multiple strain ...

To provide excitation to the load cells and measure the voltage output, you usually want to use an amplifier to condition the circuit.

Full-scale output range is typically 2,000 mV, 10 times that of traditional strain-gage load cells. Typical sensitivity is 40 mV/lb, with response times of 20 msec and large signal-to-noise ratios.
