Research on wearable devices and sensors applied to older adults has witnessed significant growth, primarily focusing on health monitoring but also on researching real-world applications of urban walking, specifically, walkability. The use of pedestrians' bodily responses to the environment, known as the people-centric sensing strategy, has been demonstrated to be more suitable for detecting challenging environmental conditions and enhancing walkability. However, the extent to which such data may accurately pinpoint environmental distress in a particular demographic, such as older adults, has not been thoroughly investigated. The purpose of this in-progress systematic review of the literature is to outline the strategy employed and highlight some preliminary findings on the use of wearable sensors or sensor-based technologies in gathering the bodily responses of older adults and/or their family caregivers to stimuli originating from real urban walking scenarios. Our preliminary findings showed that the current research on using wearable devices to detect bodily responses in older adults (or informal caregivers) population in relation to walkability in outdoor environments tends to exhibit a uniform strategy, that is, collecting physiological and location data from older adults through controlled outdoor walking routes using wrist-wearable and GPS;training supervised classifiers to differentiate between physiological stress and non-stress signals to environmental conditions of external interaction;and finally, using hotspot analysis to group together individual physiological responses in areas with high-stress interactions with the external environment using GIS. Although the body of literature appears to be still in its early stages, using wearable sensors and a GIS-based approach could be a promising method for spatio-temporally capturing people's direct bodily responses to the environmental stressors, and this offer rooms for potential integration of simulation-ba

Wearable sensor technology is revolutionizing several research fields, ranging from healthcare to fitness monitoring or biometric recognition, thanks to its many advantages against potential alternatives, such as non-invasiveness and long-term operation capabilities. In more detail, seismocardiography (SCG) and gyrocardiography (GCG) are emerging as useful tools for cardiovascular assessment, relying on inertial measurements of cardiac activity. However, the knowledge and confidence about these signals is still limited in many fields, including the medical one, where the use of electrical measurements, such as those obtained via electrocardiography (ECG), is largely preferred. This paper presents a pioneering study about the possibility of converting SCG and GCG data into ECG-like representations, with the aim of expanding the applicability of inertial wearable sensors to scenarios where their characteristics could provide relevant benefits, yet there could still be the need to exploit knowledge regarding electrical heart activity measurements. In more detail, the effectiveness of recurrent neural networks (RNNs) in performing such task is here investigated. Extensive experimentation on a public dataset demonstrates the feasibility and efficacy of the proposed method in generating signals that significantly resemble the desired ECG data. The capability of the proposed approach in reproducing relevant characteristics of ECG signals in the created data is evaluated considering two potential real-world applications, regarding heart rate estimation and ECG-based biometric recognition.

Gait analysis is a crucial method for evaluating and treating individuals with walking-related conditions. The process is typically utilized in hospitals or specialized gait labs, often involving tools operated by medical professionals. However, conventional methods have become more time-consuming and costly, leading to decreased accuracy in gait analysis. Wearable sensortechnologies have emerged as a solution. This project introduces the i-Shoe, a smart insole equipped with eight force-sensitive resistors (FSR) and a low-power microcontroller to capture gait features. A mobile application displays real-time sensor data and an average heat map, showcasing the most concentrated pressure area in the foot. Machine learning algorithms are applied to identify abnormalities like flatfoot or imbalance. The system has been successfully tested on several individuals and has potential applications in diabetic foot detection, rehabilitation, and monitoring athletes' gait.

This paper presents the methodology applied to determine the mechanical failures in an internal combustion engine caused by the application of artificial intelligence in the classification of mechanical failures associated with the cancellation of cylinder work, that is to say this methodology is applied on the data obtained from the signal of the KS sensor (Knock sensor) and the CMP sensor (Camshaft Position sensor) during engine operation. To evaluate the data obtained, the acquisition of samples applied to different operating conditions is carried out, after which an attribute matrix is created that allows a selection and reduction of variables with the application of methods based on the Random Forest architecture. Subsequently, an ANN (artificial neural network) and an SVM (support vector machine) was created and trained, from which a classification error value of 0.1267% and 0.0067%, respectively, was obtained.
