“…Although several data acquisition systems are using sensorized insoles based on resistive sensors (Abdul Razak et al, 2012;Ivanov et al, 2019;Silva et al, 2017), the same structure can be observed in all of them, where a sensor is subjected to a load and has its electrical resistance changed inversely proportional to loading (Abdul Razak et al, 2012). An electronic circuit records this resistance change where an analog-digital converter (ADC) transforms the signal into binary information, and then the microcontroller can filter and process the data.…”

“…Currently, several publications are about prototypes of sensorized insoles that use resistive sensors to capture data (Perry and Burnfield, 2010; Sunarya et al , 2020). This type of sensor can be purchased commercially and used for instrumentation of conventional insoles (Ivanov et al , 2019; Silva et al , 2017), or they can be made using printed circuit manufacturing techniques on flexible circuits (Lueken et al , 2020). Many studies that propose different designs for sensorized insoles use commercial force sensors, limiting customization for application (Subramaniam et al , 2022; Hsu et al , 2018; Hegde and Sazonov, 2014).…”

Purpose Currently, several studies have been published using sensorized insoles for estimating ground reaction force using plantar pressure. However, information on design parameters, manufacturing techniques and guidelines for developing insoles is scarce, often leaving gaps that do not allow reproducing the insole. This study aims to empirically investigate the main parameters of constructing a sensorized insole for application in human gait. Design/methodology/approach Two devices were built to evaluate the force sensors. The first focuses on the construction of the sensors with different settings: the density of the sensor’s conductive trails (thickness and distance of the trails) and the inertia of the sensors (use of spacers to prevent unwanted readings). The second device focuses on the data capture and processing system: resolution of the analog–digital converter, acquisition rate and sensor activation level. Findings The resolution increase of the analog–digital converter and acquisition rate do not contribute to noise increase. Reducing the sensors’ coverage area can increase sensorized insole capacity. The inertia of the sensors can be adjusted using spacers without changing the electrical circuit and acquisition system. Originality/value Most sensorized insoles use commercial sensors. For this reason, it is not possible a full customization. This paper maps the main variables to manufacture custom sensors and data acquisition systems. This work also presents a case study where it is possible to see the influence of the parameters in the correlation between the sensorized insole and an instrumented treadmill with a force platform.

This extensive review examines sarcopenia, a condition characterized by a loss of muscle mass, stamina, and physical performance, with a particular emphasis on its detection and management using contemporary technologies. It highlights the lack of global agreement or standardization regarding the definition of sarcopenia and the various techniques used to measure muscle mass, stamina, and physical performance. The distinctive criteria employed by the European Working Group on Sarcopenia in Older People (EWGSOP) and the Asian Working Group for Sarcopenia (AWGSOP) for diagnosing sarcopenia are examined, emphasizing potential obstacles in comparing research results across studies. The paper delves into the use of machine learning techniques in sarcopenia detection and diagnosis, noting challenges such as data accessibility, data imbalance, and feature selection. It suggests that wearable devices, like activity trackers and smartwatches, could offer valuable insights into sarcopenia progression and aid individuals in monitoring and managing their condition. Additionally, the paper investigates the potential of blockchain technology and edge computing in healthcare data storage, discussing models and systems that leverage these technologies to secure patient data privacy and enhance personal health information management. However, it acknowledges the limitations of these models and systems, including inefficiencies in handling large volumes of medical data and the lack of dynamic selection capability. In conclusion, the paper provides a comprehensive summary of current sarcopenia research, emphasizing the potential of modern technologies in enhancing the detection and management of the condition while also highlighting the need for further research to address challenges in standardization, data management, and effective technology use.
