### Mesh and Study Validation
Using COMSOL, the potential difference is measured under varying pressures. The voltage readings on the volt scale increase as the pressure applied increases for the various proposed configurations. As the voltage readings of the sensors increase with increasing load pressure, our paper's \begin{table}

Table 3: _Cont._findings are comparable to those of the above-mentioned studies. Higher voltage readings are displayed by the sensors closest to the load pressure. The results reveal that changes in load position and magnitude influence the sensors' voltage readings due to varying points of load contact with the structure at different load speeds. One can notice that sensors' voltage values increase as the load site moves away from the structure's fixed edge, with the highest voltage values for sensors L2 and R2, which are closest to the load location. The results also validate the accuracy of our study as the readings of the symmetrically defined sensors L1, L3, and R1, R3 are comparable. The input parameters data set provided shows how voltage readings can be used as a load speed sensor for the IoT. The simulation research can adopt a variable load distance step based on data pipeline needs and provide more speeds. This reveals a load's magnitude and speed of motion.
