“…However, resistive sensors (RSs) have prevailed over their peers, in part due to their small size, low energy consumption, and minimal thickness [ 4 ]. Works, such as [ 1 , 5 , 22 , 23 , 24 , 25 , 26 ], have researched the detection of footfall through the use of embedded systems with FSRs. An FSR works by mapping the footprint using a vector of RSs.…”

“…The dimensions were taken in relation to the sensor’s active area of 5 mm and the medianof the selected ages. After establishing the dimensions, we initiated the location of the sensors in order to obtain the most stable foot pressure values in relation to the types of footprint [ 1 , 5 ]. The latter foot zones are shown in Table 1 .…”

“…This process was carried out with operational amplifiers (OAs). Equation (1) shows the gain of the OA with a high input impedance, where R G is the resistance that defines the gain factor and R FSR stands for the value of the internal resistance of the FSR.…”

“…The major functionality of the foot is to provide the necessary support and propulsion for the human body to move in a bipedal manner, carrying out different locomotive activities throughout the day. The study of foot bio-mechanic systems (FBSs) has allowed researchers to study and detect bad posture and the inadequate balance of the body [ 1 , 2 , 3 ]. Among the diverse research on FBSs, the analysis of foot sole pressure has become an essential detail for the proper diagnosis of problems in the lower spinal column, muscles, and joint injuries [ 4 ].…”

“…Several research efforts in the area of podometry have defined physiological and anatomical disorders related to human walking [ 6 ]. Among the main concerns, researchers have identified the use of different types of footwear, extreme forcing of the foot, and the limitations of flexion and extension [ 1 ]. The latter can be appreciated from the variations in the balance of the child’s foot, which generates, on the one hand, a concern for parents who receive sporadic medical consultations, which lead to aggressive treatments of the normal evolution of the foot, causing injuries and limiting the functional purpose of the joints.…”

The analysis of plantar pressure through podometry has allowed analyzing and detecting different types of disorders and treatments in child patients. Early detection of an inadequate distribution of the patient’s weight can prevent serious injuries to the knees and lower spine. In this paper, an embedded system capable of detecting the presence of normal, flat, or arched footprints using resistive pressure sensors was proposed. For this purpose, both hardware- and software-related criteria were studied for an improved data acquisition through signal coupling and filtering processes. Subsequently, learning algorithms allowed us to estimate the type of footprint biomechanics in preschool and school children volunteers. As a result, the proposed algorithm achieved an overall classification accuracy of 97.2%. A flat feet share of 60% was encountered in a sample of 1000 preschool children. Similarly, flat feet were observed in 52% of a sample of 600 school children.
