SummaryMeasuring the ground reaction forces of the single legs is indispensable to understand the dynamics of legged locomotion. Due to the technical state of the art investigations are limited to animals with a body mass above 1 g. Here we present the design, fabrication, calibration and performance of a novel ultra-miniature force platform at the micro newton level. The sensor was built using the stereolithography technology and had been equipped with semiconductor strain gages. We found a highly linear signal response in the calibrated force range to ± 1300 μN. Individual tests revealed that our force plate still shows a linear response at forces around 4 mN confirming the particular robustness. The sensitivity is above 50 V/N in all directions which makes it possible to resolve forces of 10 μN. Moreover, we demonstrated the suitability of the device on the basis of a typical ground reaction force measurement of Formica polyctena.
