rehabilitation as it provides objective data to aid the decision-making process by the healthcare staff. [1,2] Typically, this evaluation is done using a combination of inertial measurement units, sensorized mats, or force plates, and video inputs. [3-7] However, the use of mats limits the scope of the analysis to specific sessions and areas. While this technique provides the most detailed data available, point-of-care analysis through insoles sensitization has become an alternative. [8-13] The possibility to continuously monitor feet pressure and other gait parameters, offers valuable data not only in orthopedic rehabilitation [1,2,14] or the assessment of deformations such as the flat foot [15] but also to improve athletes' performance [7] and to mitigate diabetic neuropathy complications, [16,17] neurological disorders, [6,18-20] among others. Different pressure transduction mechanisms have been explored successfully for this application such as piezoresistivity, [9,10,21-25] capacitive sensing, [12,26] piezoelectricity, [27] triboelectricity, [28-31] optical line-of-sight sensing, [8] and fiber Bragg gratings. [11,13] To integrate such sensors into insoles, they can be added either as an extra component, printed or directly integrated using a functional material as the insole. Graphenebased materials have proven to be an interesting platform for mechanical sensing. While single-layer graphene is constrained to gauge-factors ≈2 as most bulk piezoresistive materials, [32] reduced graphene oxide (rGO) foams have demonstrated high sensitivity while being a low-cost technology. [33,34] Graphene flakes in the form of inks can also be printed directly onto materials, providing them with electrical conduction and sensing capabilities. [35] Alternatively, laser-induced graphene (LIG) can be directly synthesized on different materials, using the substrate as the carbon source. [36-38] LIG usually arises as a foamy material with electrical characteristics similar to those of good quality rGO, without requiring wet chemical processes involving dangerous chemicals like those used in the production of graphene oxide and its subsequent reduction. With the ability to be patterned in a fast and inexpensive way, LIG has attracted the interest of researchers for its use as active material in different biomedical applications. [38-41] The formation of LIG is carried out by the irradiation of a substrate with a high-power density laser source, leading to the instantaneous carbonization of the precursor material within a protective plasma created by the gaseous Monitorization of gait-related parameters is of the utmost importance to prevent complications in several diseases, ensuring affordable healthcare for the growing amount of chronic, lifestyle-related diseases and also for improving motion performance. Sensorized insoles allow to both pressure data and gait timings to be extracted non-intrusively in a point of care paradigm. Laserinduced graphene (LIG) offers a path to the integration of sensors in different kinds of materia...

“…Many foot pathologies can be diagnosed by the footprints, such as the type of foot (hallux valgus, clubfoot, and pes planus) [1], diabetic foot [2], pathological plantar hyperkeratosis [3]. Moreover, the footprints reflecting a large amount of information regarding people's health status and gestures can also provide valuable information for fall prediction, the diagnosis of many diseases and rehabilitation therapy.…”

Footprints can provide much valuable information for fall prediction, the diagnosis of many diseases and rehabilitation therapy. This paper aims to propose a statistical method for footprints analysis based on a large-scale high-density piezoresistive film to replace the manual work of obtaining the main parameters of footprint data. Firstly, data acquisition devices are developed to obtain the plantar pressure distribution by measuring the voltage changes caused by the applied pressure on the piezoresistive films. Subsequently, a specific software is developed to receive the data from the designed signal acquisition devices through the serial port and visualize the footprints, and a statistical method is proposed to distinguish between left footprint and right footprint and to obtain the direction of the footprints and the step length. Eventually, a series of experiments are conducted to obtain the accuracy of the proposed method used for different people's feet and with different walking speeds.
