Figure 1.

Left side: Schematic of SensFloor. On the bottom left module, the power transmission ways are shown (PSU = Power Supply Unit). The top left module shows the coordinates of a module center ( $p_M$ ) and a sensor field ( $p_f$ ). The module length is typically $l_M=0.38$ m for Gait Analysis. The electric capacitance is measured on the sensor fields which are shaped as triangles. Right side: SensFloor sensor modules in the study lab. This photo was taken during the installation of the sensors. Afterwards, a carpet was laid on top of the modules, concealing them completely.
